DSC - DIGITAL SOUND CHIPS OPUS MAX BOARD


DSC - DIGITAL SOUND CHIPS

From the creators of the Bluebox synthesizer comes a new project for DIYers. Currently on Kickstarter here.

"A short introduction to the OPUS MAX BOARD music computer and development board for making music gear with the STM32H750 micro controller. https://digitalsoundchips.com It will come with a profession grade synthesizer and audio effects unit to loop sounds through the board externally. And with information on how to make your own music gear like synthesizers and audio effect units."



"Back in 2011 the worlds smallest synthesizer DSC Bluebox was made, but vent by unnoticed. This time Digital Soundchips that made the synthesizer is back, and want to solve the problems that they once went through for you and others.

Now we a ready to present a single-board computer for audio plugins and music gear. And with one profession grade synthesizer plugin, and a multi effects unit to loop audio through. That uses a open plugin standard with plugins on microSD card.

Imagine making professional music hardware gear, based on a super simple audio plugin format. And develop music gear that can use several plugins simultaneously.

We want to make a pre-configured scalable solution, so you can start writing your audio code and run ready-made plugins. And lower the development time for new music gear from years or month's, to weeks.

Lets make it faster and fun to develop commercially viable professional music gear.

Goals

Provide a development board with 24bit audio I/O, MIDI I/O, 2 USB and microSD slot. Connectors for 4 MIDI in, 4 MIDI out, 2 stereo in, 2 stereo out on 3.5mm jacks. Expandable with custom hardware user interfaces. With a scalable and reusable design for custom boards for commercial end user products.
Make a portable small easy to use audio plugin format without GUI called DSCDSP.
Deliver a DSC Bluebox synthesizer plugin to run on the board.
Deliver several effect units with full source code to run on the board.
Make it easier for you to develop commercially viable products.
Double your profit margins for your future products.
Why we decided to make the OPUS MAX board

To give you a give you a board that you can be used in music production.
To give you a board that can be used for making new audio gear.
To give you a single-board computer, with all the music gear connectors that no other board delivers.
A platform to scale down to fit a huge range of applications.
To get you started with coding, without loosing huge amount of time on configuration, and without getting you bored with the usual hundreds of nerdy details taking month's to set up.
To give you a standard hardware configuration for the worlds fastest rapid prototyping of music gear hardware.
The OPUS MAX development board came to life, because there wasn't any good hardware available to base a huge range of music gear around. Other boards for audio gear development, don't have connectors out of the box for more complex designs or is for making toy like boring products.

We saw that it for the first time in history was possible to make a platform that would end the need to change platform for each new product idea based on your requirements and cost restrains.

We have a development board ready, optimized for best performance and simplicity for making a huge range of hardware.

And we have code for a new simple plugin standard for effects and synthesizers, and saw that this would make it possible to run a huge range simultaneous plugins.

The basic idea behind the Opus Max board and comparison with Arduino and Raspberry Pi

The goal is to crate something like Raspberry pi and Arduino with and USB firmware programming via USB. Focused on developing commercial music gear. A board to make development of commercial music gear accessible to a huge range of people.

The opus max board gives capabilities that Arduino and Raspberry Pi can't deliver even when using them together.
The Opus Max board has a expansion connector much like Raspberry pi and Arduino but more suited for audio applications.
Draw only 0.5 Watt on full speed compared to Raspberry Pi's 6 Watts.
It has no background process that eats a lot of CPU like the Arduino that makes it almost useless for audio.
No upstart time like Raspberry Pi.
No need to source separate hardware for processional audio and MIDI ports.
Specialized for audio gear so all examples relates to making audio gear fast.
Not being locked down like the Raspberry Pi for creating single board solutions.
Uses a ARM MCU that is available for anyone to buy unlike Rasberry Pi.
Has computing power and memory that Arduino don't even come close to.
Uses few components, with a MCU with built in RAM and flash.
Lowers the latency for real-time performance to almost nothing compared to Raspberry Pi and gives you 4 audio channels in instead of zero and 4 audio channels out as standard.
Usable for smaller projects for a low cost, so you can sell products and still have a profit margin, that isn't possible with Raspberry Pi.
Uses components that can be bought from many component distributors for a low cost, that's impossible with Raspberry Pi.
No external memory chip is needed (as patches can be stored and loaded from flash as shown in DSC Bluebox), or use SD card for samples, patches and plugin's. Something that's totally impossible with Raspberry Pi on every level.
The OPUS MAX board gives you a open plugin format for rapid prototyping usable for low cost audio gear hardware, something that's previously unheard of on any platform
The chip STM32H750 has 1 Megabyte RAM built in and firmware can be loaded to the internal flash via USB (without any extra external components or any pre-loaded firmware or boot loader). Giving a simpler hardware design than Arduino.
Can run several effect units and synthesizers simultaneously without extensive programming or hard to get knowledge, with highest performance. Making rapid prototyping of more complex audio gear hardware possible with great ease of use, something previously unheard of.
The primary reasons for using the OPUS MAX board is...

Don't need a huge amount of knowledge and preparation for making your own audio gear products. And to drastically reduce development time for new audio gear.
Gives a standardized way to run plug-ins for huge range of embedded music gear applications, that also can be locked down for you proprietary products with your own firmware that easily can be loaded via USB.
A suitable ground design for a huge range of music gear applications and products, and make it easy to make products with profit margins.
A product even for end users of effect units and synthesizers and more.
Code dependencies is kept to a minimum with DSCDSP plugin format. Something that's impossible with VST format.
A couple of use cases

Use case - custom hardware development...

Make a fast software prototype for effects and synthesizers in minutes and compile code and use MIDI controller and test it out.
Make your own expansion board prototype for your custom user interface (possible even without making your own custom PCB design). Or connect faders, knobs, buttons and switches directly to the board.
Design and build a expansion card and a front panel. Example projects will be made available for the free program KiCAD(PCB) and board outline in DXF format.
Make your own complete custom PCB board with STM32H750 on it in any PCB CAD program.
Use case - generic audio hardware…

Use the DSCDSP plug-in host on Opus Max board.
Program a plug-in (sell or share with others).
Buy or download free plugins (after the kickstarter is finished the plan is to make a marketplace for this plug-in format, where people can sell and download plugins).
Make your own front panel or casing or buy something ready made (the goal of this project is to make this as easy and strait forward as possible).
Inspiration for the DSCDSP plugin format

VST plugins - as it's used for audio and synthesizer plug-ins and include MIDI.
Reason plugins - as it has a has a common way to store and load patches, much like...
The FV-1 DSP reducing the patches to audio in and out and a few knobs, without any code needed for changing patches, reducing the complexity to a minimum.
The DSCDSP plug-in host takes care of loading and storing patches and has a simple framework to run several patches simultaneous, that can be locked down for your product or stay open and load third party plugins. And give you multi-timbral capability automatically without writing code.

The DSCDSP plugin host make it possible to run many audio and synthesizer plug-ins simultaneous, that make use of MIDI for control and patch changes.

The DSCDSP is made for music gear, as it doesn't define a GUI and keep CPU usage to a minimum with a low latency that is expected of hardware.

The DSCDSP plugin format, makes it as simple as possible to make plugins, so you can make a full plugin with everything expected of it in hours instead of months. It makes it easy to get started and make something useful, that later on can be expanded on and get several useful products along the way, and so you later on can reuse your code for other plugin formats. Or use it as a steeping stone to make your own full custom firmware later on.

The DSCDSP and OPUS MAX board gives unheard of low latency for a plugin format beaking the 1ms margin, with more than 100 times lower latency, down to under 0.01ms latency.

Other use cases for the DSCDSP plugin format is usage in computer games and built into applications. So you can sell plugins and code for usage in apps or games.


OPUS MAX has the following connectors

2 stereo out 3.5mm audio jacks with two CS4344 24bit stereo DAC’s.
2 stereo in 3.5mm audio jacks with two CS5343 24bit stereo ADC’s.
4 MIDI in 3.5mm TRS jacks, changable to type-A or type-B 3.5mm MIDI jacks without adapters.
4 MIDI out 3.5mm TRS jacks, changable to type-A or type-B 3.5mm MIDI jacks without adapters.
1 USB type-B connector for power, and communication with computers.
1 USB type-A connector for communication with USB devices like MIDI controllers.
1 microSD card slot, for storing and loading samples, audio plug-in's, patches, configurations and data, and can transfer 100Mbytes/second.
1 Expansion connector with a 40-pin pin-header, giving access to 2 SPI buses, 3 UART's, 1 I2C bus, 11 high speed 16bit ADC channels (can be over-sampled to 20 bit, 8 of the ADC channels can be used as 4 balanced analog input pairs), 2 DAC channels that can be used for audio out (with capacitors in series to connect directly to audio out jacks) or other purposes, 1 SAI interface for other sound expansions like PC'97, I2S and SPDIF. It also has a full 16 pin GPIO bus and a full 8 pin GPIO bus. In total there is 35 GPIO pins at 3.3V, and 24 of them is 5V tolerant. The 24 I/O pins that are 5V tolerant can be used as I/O to communicate directly with old hardware that use 5V TTL logic, but all GPIO's can be used as outputs to 5V TTL logic.
Additional unpopulated pinheaders

1 serial 2-wire debug port.
1 UART for 5V communication.
8 Pinheader's to repurpose 8 of the 3.5mm TRS jacks for other functions.
4 Pinheader's to the 4 stereo pairs.
All positions for pinheader’s are on even positions with 100mil (2.54mm) separation, so you can build own expansion boards on standard perfboard or stripboard like veroboard and more easily make your own PCB's. The 11 ADC 16bit channels on the expansion header, can for example be oversampled to 20bit audio in. The board also has 4 programmable LED's, one red, one orange, one green, and one blue named “engine”, “patch”, “param.” and “value”. It has 1 reset button and 5 other buttons named "+", "-", "enter", "exit" and “save”. And the boot pin is available on the expansion connector, so you can design gear with upgradeable firmware, without need for opening any enclosure.

The board dimensions is 110mm x 73mm to be able to fit between eurorack rails, and is also designed to be used in extruded aluminium cases. The board has 4 standard M3 mounting holes for spacers and standoffs.

Here is some project ideas:

Digital Synthesizers.
Chorus , Flanger.
Sample player from SD-card.
MIDI splitter.
Drum machines.
Stereo vocoder.
Analog synthesizers with patch memory, and MIDI.
MIDI Router.
Sequencers.
Music workstation.
MIDI USB host.
Samplers.
Digital audio mixer.
Eurorack modules.
MIDI effects unit.
Digital audio effects.
Loop pedals.
USB soundcard.
MIDI controllers.
Reverb, Delay.
DJ products.
USB MIDI interface.
MIDI patch loader.
Distortion, EQ.
Audio recorder to SD-card.
MIDI merger.
Standalone music computer.
Makes it simple to make full custom PCB's for one board solutions, with only one IC chip

The STM32H750VB is optimized for low cost, has a high-performance ARM Cortex-M7 core, with almost double the power efficiency of the older Cortex-M4, and has a 64bit FPU and DSP instructions. And it can be bought for a very low cost from a wide range of electronics suppliers on internet.

This chip can be used stand alone and save and load patches, as it ha built in flash and stereo DAC for audio and loads of high speed ADC's for audio in, knobs and faders. And can be directly connected to computers and USB MIDI controllers.

The OPUS MAX development board gives a design that is scalable for a huge range of products.

Many high performance generic development boards, also use components that isn't available for smaller companies and adds hundreds of thousand for the stating cost for manufacturing boards. All used components on the OPUS MAX is available for low costs even in minimal quantities. So you can make your own custom boards if needed.

Lets lower the cost, lower the current consumption, simplify the electronics, lower the development time, widen the product possibilities and make things possible.


What OPUS MAX development board is all about

Opus Max is about making your own commercial products and save time and money and get a high profit margin.

Or to use or develop plugins with the opus max board. Examples will be made freely available for making plugins and how to make a host, so plug-ins can be recompiled for Windows Mac and Linux to fit VST or other plug-in formats.

To make a plugin system like VST but for use on high performance music hardware, computer games and apps, instead of only music programs. And a format that is more portable for compilation on different platforms including custom hardware or applications where a user interface for plugins isn't wanted, like computer games.

A development card for music studio gear...

Develop your own firmware for the Opus Max board that can easily be loaded over USB.
Develop a plug for the plug-in host firmware (the DSC DSP host firmware for the opus max board).
Save time and money, and get into business faster and for a lower cost with higher profit margins and higher re-usability so you don't lose time and effort and can sustain your business.
A development card for new music gear...

It's easy to load the Max Opus board with new firmware over USB ( and it's free for anyone to make new firmware if they need that) without any dongle, adapter or additional programmer.
Full schematic will be provided and development tools is widely available, changes can be made with your computer over USB without any additional hardware.
Reusable and scalable design (buy licence to change hardware for your proprietary board design and save huge amount or time and money and maximize your profit margins). Save huge amount of time effort and money by not starting from scratch.
Full design files for KiCAD to design, modify and manufacture your own expansion cards.
Ready made, down-scalable design, is a huge amount of times faster than to scale up a design (the full card design took a couple of months to make, but the design has been scaled down to several different versions within a few hours without problems).
Design synthesizers and audio processors and more (get started fast with our coming community forum).
A development card specially made for real professional music gear.
A music computer with audio plug-in system (with free info for development of plug-ins and own plug-in hosts)...

Run several plug-ins simultaneous on the same card, or use several cards in your studio.
Make your own plug-in host for your own hardware and firmware or use a ready made firmware with plug-in host.
Use case: own synthesizer with different synthesizer and audio effect engines.
Recompile your code for Windows, Apple, and Linux (reuse your development efforts).
DSCDSP plug-in host (put multiple audio plug-ins on SD card for simultaneous performance).
Run plug-ins from SD card or lock it to your hardware with your own firmware.
Develop your own DSCDSP plug-in's or use others.
It's much faster to develop DSCDSP plugins, as you don't need to make a GUI.
Easy to port your plug-in code for further development later (no special dependencies).
Plug-in standard made for usage in music gear (learn fast, with a minimal need to know basis).
A new hardware standard for music gear based on euro-rack...

Will give a new standard 3 inch audio rack instead of the normal 19 inch format.
Smaller units (3U high euro-rack modules turned on the edge for super small rack).
Smaller cost (signal levels without conversion for smaller hardware cost).
Great portability, and even great for battery driven applications if you base your design on the OPUS MAX concept.
Faster development, you only need a front panel instead of a complete casing for your electronics to make a complete product.
Smaller starting costs (a PCB as front panel, and free KiCAD design files), that will make units with starting costs lower than ever possible before.
Makes it faster to develop audio and saves money and space, and lower shipping costs.
By not using connectors used for euro-rack, costs is lowered dramatically, as signal converting is kept to a minimum.

This is to fast and powerful for my needs

Don't worry, you can lower the processing speed and get a lower power consumption. Running at full speed it will draw less than 0.4Watt. But you can easily lower the power consumption by changing the PLL settings. Set the processing speed to 1/10 of the highest possible and draw 0.04 Watt and still have 100 DMIPS processing power (100 million instructions per second). Or set it to 1 hundredth of the highest processing speed and still be able to make a cool synthesizer or effects unit, and only draw about 0.004 Watt.

Just use the subset of functionality you need on the board. It is much easier to strip away functionality you don't need in your design, than to take a simpler design and try to scale it up. You will save yourself a lot of time this way.

And if your next design will need something more powerful, then you can start with the same development board and don't need to learn something new and reuse your code with a breeze. And you can use the same components for many products and save money on bulk orders and keep a small, simple inventory for production.

1MB RAM may be to much for many synthesizer applications, as huge amount of professional music gear has gotten away with a fraction of that memory. You probably will get the extra memory and performance in the MCU for free in your designs in comparison to other MCU's.

Wait I need more RAM for my design

Only 1 MB RAM can sound like a little to little. But this is well compensated with the super fast microSD card reader. You can make a sampler and load from gigabytes of sample data, and still mix a huge amount of channels. You can mix 128 channels from SD card without problems and still have a huge amount of processing power left. So with a slower MCU and a slower SD card reader, then some extra GB of RAM wold be necessary to give it a similar possibilities as this card.

1MB RAM is enough even for long delays, if you save audio delay buffer as floating point data in RAM. The FV-1 audio DSP chip that is used for delay and other things in mixer boards and guitar pedals, has less than 64kB RAM, here you have 16 times more.

One of the few applications that could need more RAM is loop pedals, in that case you can connect a few MB RAM on a simple SPI bus. But a loop pedal that saves all loops and the hole jam session to SD card (without extra RAM memory), giving 100 hours of uncompressed jamming on one 32GB microSD card.

Benefits of this dev board and plugin standard

USB programming, without extra hardware, boot-loader, or programmer in designs.
No need to design custom board to get started with developing software.
A standard for loading patches. You don't need to write your own code for loading and storing patches, making it much faster to develop plugins and dedicated hardware.
Lower latency than anything than runs on Linux.
Capable of as low as 0.1ms latency. The distance from your ears to your studio monitors will provide more latency. Use headphones if lower latency is needed.
Optimized for developing gear for mass production benefits, with low cost to entry and high margins.
No need for huge RAM buffers for samples for applications.
A simple plugin standard that can be easily be implemented by music DAW's.
It makes you code portable and much easier to reuse.
Making it easier to make audio plugins for DAW's of your hardware, giving higher margins than the opposite route (going from software to hardware). And it's easier to make lookalike products that way also.
Focus is on that is special with your product, without loosing time in development on common generic stuff that don't define your product.
Run many effects and synthesizers simultaneously if needed on the same board.
What program language will be used

The goal is to make it easy to develop cost-effective music gear. And make a big directory of relevant C code to use for your projects with this card, as C and C++ today is the de facto standard for professional audio programming. There are a lot of free ready-made software, compilers and development tools to get started. We don't want to pretend that you can use other languages for music gear if you want low latency. And C or C++ is also what people also use for micro controllers, making low cost music gear possible. Anything else is not for professional grade low latency products.

What we will make and what you will get

Ready made audio effect plugins to use on the board.
A DSC Blue Box sythesizer plugin, to use on the board.

Simple code for making a platform independent plugin host will be released, so you can make your own music program and so DAW's easily can implement direct support for the plugins.
Starting with a development board will soon be the fastest and easiest way to get started developing professional music gear like synthesizers and audio effects.
A custom user interface is not needed to make something useful, as MIDI makes it easy to change patches and parameters without any user interface.
Help us to help you get started with making your own music gear. In return you get a development board and all necessary information to get you started and save time and money. And get a free synthesizer, and multi effect units running at the same time on the board.

We will make a user community so we can help each other. That's why we need your support to be able to continue the hard work and give it our best for a flying successful start and make your future products possible.

Don't despair in development

We want to spare you the headache of not meeting the price range of competitors and not having high enough margins to survive, or getting caught in endless development cycles without the feeling of getting things done for months with your custom hardware design. We want to help you diversify your products, and get a product range, and come out with new professional products faster. Not just faster, but much much faster, previously unheard of.

The DSC DSP plugin system and the OPUS MAX development board, will show it's true power when you don't just want to make one product, but many different products. The goal is that you should be able to release with many different products fast, while others struggle is still tying to get one product ready for serial production.

We also wanted it be easy and cost effective to make products, so you can make a bigger margin to survive on your products or keep a low price when people are buying in huge masses.

What development board gives you more than 2 USB, 4 MIDI in, 4 MIDI out, 4 audio channels in, 4 audio channels out with connectors. And on the expansion connector you have two more possible MIDI in and two more possible MIDI out, 11 more possible 16bit audio channels in without external ADC, or 2 extra DAC's for audio that can be used for extra simple low cost designs (that's similar to the design used by DSC bluebox).

The Max Opus board provides a simple scalable design with easy to access components for your products, with low power consumption, beat that.

Why we didn't make a board running Linux

Using Linux makes it a lot harder to make custom hardware. It also introduces much latency and it adds starting time for your products to start/boot. There is a huge difference between instant usage on power up as with this board and waiting for a development board to boot Linux. Using Linux makes it hard to compete with mass produced gear from big companies, as it raises the cost for hardware. Usage of Linux gives a higher power consumption in battery powered applications. Linux makes many simple products - like stomp boxes - impossible to hit the right price range for consumers, and still have profit margins on small production series.

Timeline

We continue to provide information and do administrative groundwork during the kickstarter campaign.
OPUS MAX boards gets manufactured, the limited edition will be sent out first.
Configuration files will be provided to auto generate the needed source code to get started.
Code will be released for the board to make effects and synthesizers, and synthesizers with effects, kept as simple and useful as possible. And basic tutorials will be made available to get examples working.
A first usable draft of the plugin standard will be provided for review, and people can come with suggestions from your experience using it.
Time and support will mostly be spent there improvements are needed.
All information and design files will be improved continuously and expanded upon.
When the plugin standard is good enough and things are documented and tutorials are written and fine tuned to the community's satisfaction, we will release code to move plugins to Windows, Mac and Linux.
Design and CAD files for making expansion board for new eurorack format will be provided and viable examples will also be made available as hardware. Design files is already made for a expansion board with 8 potentiometers, 2 encoders, a graphical LCD display and velocity sensitive keys, but need a first production run before produced in larger quantities.
Different compatible new boards will be presented and manufactured much dependent on user and market response. Different cost reduced boards for end user products will be made available with huge discounts on bulk order, with bracket prices lower than $29 per board. The OPUS MAX board will continue to be manufactured as it's maximized in functionality for development of a huge range of products, and example code and tutorials for a growing range of product examples will be made available for it. Design files for four other reduced boards is already made.
After the kickstarter is finished our goal is to provide an internet store where developers can sell their expansion boards, casings and plugins for end users, code and solutions for developers, so you can market your designs easier.
Our personal goals after this, is to provide improved custom tools and services and continue lowing the bar for time spent going to market when developing music gear, and continue providing good margins for the growing mass of successful developers.
What the Blue box synthesizer plugin has under the hood

2 OSC’s with 32 different waveforms to choose from. With PM(phase modulation), wave sequencing, and one third oscillator for oscillator sync. And sub-oscillator waveform doubling for extra fat sound.
2 Digital filters. Low Pass in series with High Pass.
1 Preamp output stage. Can be overdriven for distortion.
3 Fast step sequencers, for wave sequencing, SID drums, arpeggios and more.
1 LFO with range speed and 32 different waveforms, with phase start setting or free-running and with S&H (sample and hold) functionality.
3 ADSR’s, for filter, volume and sync. PM (phase modulation), Subtractive and True Noise synthesis.
MIDI-in: Syncs to MIDI clock, Responds to Program Change, Pitch Bend, Note Velocity, Expression Controller, Breath Controller, full parameter control by CC messages and more.
MIDI-out: Notes, Program Change, mod. wheel, CC and more is available via breakout cable.
Unique percussion mode for live performance and more.
And the OPUS MAX and DSCDSP concept will give it multi timbrality, polyphony, sound layering and multi effect units, that wasn't in the original DSC Bluebox, but will demonstrate the power of the OPUS MAX and DSCDSP concept.
A last word of thought

Our goal is to help you succeed making professional audio gear. There is a lot of boards out there, that's made for simple hobby projects. But this is the most capable board out there out of the box, for making professional audio gear.

Risks and challenges

More simple applications can get running early on this board. But as this music computer that can be used for a enormous amount of professional applications, it will be an evolving and growing platform for a long time. New software updates and source code will come over time. The hardware is less of a risk, as everything in the design is tested and checked for correctness many times, and will be continually checked in every step to shipment."
