Arduino Drum Sequencer and Arduino CV Quantizer controlling Analog Synth Drums and other Modules

video upload by Unrelated Activities

"The Arduino drum sequencer is sending MIDI to a MIDI to CV and Gate converter, the converter gates then control analog drums and send a clock to the Arduino CV Quantizer, the CV Quantizer is processing a sine wave LFO and sending gate and quantized CV to an ADSR and a VCO and VCF pair. A VCA completes the patch. Arduino Drum Sequencer and Arduino CV Quantizer controlling Analog Synth Drums and other Modules."

The SIDuino

SIDuino demo song from gaess on Vimeo.

"This video shows the SIDuino shield for the Arduino board in action. Sound quality is not the best, because i've used my cameras mic, but you'll get the idea what is possible to do with it!"

The video above is from 4 years ago so this not a new project, however I do not believe it has been featured on the site before now.

via Arduino Playground

"The idea is to emulate the original SID chip (Sound Interface Device) from the Commodore 64, cos its hard to get, and in addition to have the whole interface and programmability from the arduino. The SID-emulator code was programmed by C. Haberer, see Roboterclub Freiburg for details. The SID-shield has been designed by dusjagr/SGMK, the SIDuino i2c-shield has been designed by gaess.

The systems allows you to create original 8-bit sounds programmed and controlled via the Arduino board.

SIDuino i2c

The latest SIDuino version uses now an i2c connection between arduino and shield. Arduino's hardware serial port can thus be used for MIDI-Input. With te new code, we don't need any Software Serial commands any more and have been able to speed up the whole system considerably. We have a debbugged Version 0.3 of the shield now online. You can find schematics and a running code example on the separate SIDuino i2c page."

Arduino SpeakJet Module Prototype

Arduino SpeakJet Module Prototype from ignacio dacio on Vimeo.

via Ignacio Dacio on The MATRIXSYNTH Lounge

"This is a module I built early this year.
It is an Arduino driving a SpeakJet chip to produce allophones and weird synth sounds.

It works on an algorithm coded in Arduino, which is basically a sequence with a variable, the slide potentiometer position amount, which makes the sound change.

The rythm and velocity must be changed into the code.
It has an LCD to display the amount of the slide potentiometer. It says "Voice Pitch" but it could be anything.
The first slide potentiometer is the volume.

Based on the sequence you can produce robot voices.
The easy way should be to add another chip which translates text into sound."

ArdCore - Snazzy FX - Arduino - Eurorack - Installation Demo

YouTube Published on Jun 7, 2012 by DJjondent

"The 1st 29 seconds of this video demos how to upload a patch to the ArdCore Eurorack Module by Snazzy FX
The video is silent till 30 secs....so you dont have to turn your speakers up.

I only got this today.... finall an Arduino in Eurorack form.

An Arduino is a micro-controller ( computer chip ) which can be programmed to act as you wish. So this module has the potential to be a VCO or filter, or ADSR envelope.... they say anything you like..

It all depends on the code ...So I downloaded this bit of random code (Pretty 1a_pot) from "github" just to test it out.
https://github.com/darwingrosse/ArdCore-Code

This code turned out to be a sort of VCO (very different to your classic oscillator) ... or is it supposed to be a random audio source. ????
Anyway, it does respond to CV modulation.
I'm modulating it with the anti-oscillator from Wiard which is a radical VCO in its own right.

-------------------------------------------------------------------------

Hopefully this will get everyone else up and running fast.
There is no manual out as yet however these are the installation instructions

CB's DIY Modular Synth: 2-16-2016 Arduino oscillator, MIDI, and PT2399 digital delay circuit

Published on Feb 16, 2016 Chris Beckstrom

"More about this project:
http://www.chrisbeckstrom.com/portfol...

This week I built two very exciting modules: an Arduino-based digital oscillator with MIDI input (!!!) and a PT2399-based digital delay circuit. Still working out some kinks on the Arduino oscillator, but for now it has 3 programs, each with a crossfade between different waves. Program, frequency, and wave shape (crossfade) are all voltage-controllable. In addition, the Arduino spits out gate voltages when it receives MIDI note on messages, which I can then use to trigger envelopes, sequencers, etc.

This particular patch is a MIDI sequencer generated by Qmidiarp on linux whose root is determined by the little MIDI over USB keyboard, then sent via MIDI cable to my Arduino oscillator. The output of that goes into an amp (the Arduino is pretty quiet) and then into a VCA whose attenuation is being modulated by the gate voltages. Then into a mixer along with some delay. A triangle LFO is also modulating the frequency of the oscillator (when it's in "free" mode) and a slope generator triggered by the gate voltages is modulating the wave shape (sine to saw, tri to saw, and sine to wave-folded sine)"

FYI, I created a new Chris Beckstrom label for these moving forward. You'll find three previous posts there. A search on Chris Beckstrom will bring them up as well, along with two Bitwig videos. Lots of "New" labels for this post.

Eurorack Modules by Cavisynth

Published on Apr 20, 2016 Cavi Master

Note, this is the first Cavisynth post on the site. They have modules listed on their site as follows:

The Arudurack

"Ardurack is a multifunction eurorack module based on Arduino.
It has 8 functions all centered around pulse/square signal:

Trigger by the push of a button (2 to 100ms per impulse).
Tap-Tempo trigger (2 to 100ms per impulse).
Modulator, a voltage controlled square wave LFO. Frenquency range is fixed between 0,5Hz (2000ms) and 15Hz (65ms).
Simple square wave VCO (gated or continuous mode).
Complex square wave VCO 1 (gated or continuous mode).
Complex square wave VCO 2 (gated or continuous mode).
Noise (gated or continuous mode).
440Hz Tuner
The conception and functiunalities of the Ardurack make it differ from other modules in it’s own unique way.
Every single mode has it’s own particularity. They may seem simple at first but with well-thought and clever addons, they transform the module in a complex utility workload machine! For instance things like having a hold option on the trigger when it is high, the doubling of the modulator period by the simple push of a button or the gated mode on the VCO’s which avoids the need of an external VCA.

The developing philosopy of the module started from one constraint: The Arduino ProMini board based on the Atmega328p microcontroller. The idea is to extract all good working signal from this chip for the eurorack world. This chip only provides digital signal or square waves. Therefore every output mode is based on square wave / pulse / triggers.
Eventhough it is deliverd fully assembled, functional and equipped with the different modes explained, it is up to you to make this module yur own. You may upgrade or downgrade it’s hardware or firmware! It is possible to re-programm it with the Arduino environement and an FTDI adapter. You may also want to add more inputs and/or outputs out of the non-exploited I/O on the ProMini board. You buy the hardware, the assembly and the developping, the rest is up to you!
As to say, it is also the first official module from Cavisynth Labs.
First of a long list to come!"

The SEQ-UFD

"SEQ-UFD is a fuly & small ( 18HP ) 8 step sequencer based on Arduino.


To begin with, why this name: SEQ-UFD ?

Ok, I think “SEQ” it’s obvious, but “UFD” ? no idea?
This means absolutely nothing! Maybe you can found something but the only way is a pun in French.
In French, SEQ-UFD is pronounced the same way as C.Q.F.D (cé. cu. èf. dé )
C.Q.F.D: “Ce qu’il fallait démontrer” -> This was to be demonstrated. Voilà!

Number of steps selector controled by knob
Multimode controlled by knob or CV
Internal or external clock ( internal: 20 to 2500 ms )
Trigger output: ideal for EG (70 ms)
External clock input + reset steps input
8 separated gated output ( like Doepfer A-161 clock sequencer )
8 steps with voltage controled by knob
CV outpout with range controled by knob
List of available modes:

Step selector (hold step) (1 to 8)
Forward routine ( 1, 2, 3, 4, 5, 6, 7, 8)
Backward routine ( 8, 7, 6, 5, 4, 3, 2, 1 )
Forward-backward routine ( 1, 2, 3, 4, 5, 6, 7, 8, 7, 6, 5, 4, 3, 2, 1)
Crab routine based on the first step ( 1->2, 1->3, 1->4, 1,->5, 1->6, 1->7, 1->8 )
Z (zed) routine ( 1->5, 2->6, 3->7, 4->8 )
Random

Like the Ardurack, the developing philosopy of the SEQ-UFD started from one constraint: The Arduino ProMini board based on the Atmega328p microcontroller. The idea is to extract all good working signal from this chip for the eurorack world. This chip only provides digital signal or square waves. Therefore every output mode is based on square wave / pulse / triggers / gates.
An ideal context for making a sequencer!

Always like the Ardurack, you may upgrade or downgrade it’s hardware or firmware! It is possible to re-programm it with the Arduino environement and an FTDI adapter. You buy the hardware, the assembly and the developping, the rest is up to you!"

The Minipass V1

"Passive multiple Version 1

You can link A with B & B with C by switch.
If the two switch are on the right (link), every plug are linked.

This is equivalent:

3 x 4 multiples
1 x 4 + 1 x 8 multiples
1 x 12 multiples
Technical specifications:

Format – Eurorack
Power consumption – none (passive module)
Module width – 4HP (20mm)

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.

"In this video, Chromeo's Patrick "P-Thugg" Gemayel builds an improvisatory track using only the Moog Werkstatt-Ø1 and a simple drum pattern. The Werkstatt-Ø1 is a patchable, 100% analog synthesizer capable of producing a wide variety of classic Moog sonics. For this track P-Thugg summons vintage Moog basslines, expressive leads and evocative sound effects from the Werkstatt-Ø1, demonstrating the range and flexibility of its painstakingly designed circuits."

"Moog Announces World Wide Release of Werkstatt-01 Analog Synth & Online Modification and Creative Learning Portal

ASHEVILLE, NC – October 7, 2014 – Today Moog announced the official worldwide release of the Werkstatt-01 Analog Synthesizer Moogfest 2014 Kit — a patchable analog synthesizer designed to inspire the exploration and modification of classic Moog circuits while delivering a myriad of vintage and new raw, mangled, and monstrous Moog tones. This highly-portable instrument is secured in a solid-steel chassis and features a harmonically rich Moog VCO, classic 4-pole Moog Ladder filter, wide-range LFO with audio-rate modulation capabilities, ADS envelope generator, and an analog patchable header for expansive sonic experimentation, manipulation, and decimation. To demonstrate the range and flexibility of Werkstatt's classic Moog sonics, Moog has released a video featuring Patrick "P-Thugg" Gemayel, keyboard player for Atlantic Records’ band Chromeo, building an improvisatory electro funk track using only the Moog Werkstatt-Ø1 and a simple drum pattern (see video link).

Today also marks the launch of WerkstattWorkshop.com (beta) — an interactive creative learning portal containing project ideas, mod tutorials [videos below], parts lists, educational lesson plans, 3D printer files, Arduino integration and control and many other dynamic resources for Werkstatt owners. This microsite also includes Moog’s new and on-going research surrounding the use of subtractive synthesizers in STEM and STEAM high-school classrooms. Lessons in these studies are focused on project based learning opportunities, and encouraging a creative deployment of practical skills in STEM fields. All lessons and associated materials are open source and available online free to educators across multiple disciplines.

“Analog synthesizers have long had their own maker culture born of curious engineers, musicians, and hobbyists alike,” said Moog Music CEO, Mike Adams. “Bob Moog got his start at the age of 15 by studying and modifying Leon Theremin’s designs. We’d like to share our legacy of learning, music, and electronics to empower a new generation of makers to expand on our work and take it to levels we can’t yet imagine." Adams said.

In April 2014, the Werkstatt-01 Analog Synthesizer Kit was made available to Engineering VIP ticket holders at Moogfest 2014, Moog's multi-day celebration of technology, art and music. The success of the workshop at the festival prompted Moog to release a limited number of Werkstatt's to select US dealers. Starting today the Werkstatt-01 Analog Synthesizer Kit is available and in stock at all Moog Music dealers worldwide. MSRP of $329US"

WERKSTATT | Photo Sensitive Resistor
"This simple modification adds a photocell resistor to control our VCF. By using a photocell we are able to have functional control over the filter cutoff frequency by simply moving our hand closer or farther away."

WERKSTATT | Pressure Sensitive Resistor
"In this simple mod we will be exploring using various unique resistors to interact with our Werkstatt. We will be using a force sensitive 10k resistor to interact with our VCA."

WERKSTATT | Volume Knob
"We can use the power supply taps provided on the Werkstatt to add a Volume control functionality to our Werkstatt. Having a volume knob may allow players to better integrate the Werkstatt into their setup."

WERKSTATT | Fine Tune
"The Werkstatt comes with a coarse tune potentiometer in the form of the VCO FREQ knob. However, it is sometimes necessary to have a finer control over the VCO tuning. This modification adds a fine tune potentiometer to your Werkstatt."

WERKSTATT | Pitch Bend
"Many popular synthesizers have a pitchbend wheel included for dynamic musical expressions. We will use a 10kΩ SoftPot to emulate the pitchbend wheel and add a fun functionality to our Werkstatt."

WERKSTATT | 2nd Oscillator
"The Werkstatt features a single-oscillator VCO, but by patching and attenuating our keyboard control voltage to our LFO we are able to use the LFO as a second oscillator. This feature is best used to add a lower frequency Triangle or Square wave oscillator to our Werkstatt."

WERKSTATT | Arduino Noise Generator
"A popular synthesizer feature is the noise generator. This noise can be filtered and mixed with our tonal signal to add bite or create percussive sounds. In this mod we will be using an Arduino microcontroller to add a noise generator to our Werkstatt."

WERKSTATT | Arduino Arpeggiator
"An arpeggiator is an electronic instrument feature which takes played chords and cycles through the notes in sequence at a set rate. This modification will add a arpeggiator/sequencer function to your Werkstatt by adding an Arduino micro controller and manipulating minimal code."

WERKSTATT | LFO Quantizer
"Do you want to wobble? Are you all about that bass? Do you want to add face melting to your resume? This mod is for you. Using the Arduino and some code we can create an LFO rate quantizer to sync our keyboard notes to LFO rate settings at a specific tempo."

"The Groovesizer is an arduino-based DIY 32-step sequencer / synth - the project is based around a custom PCB that in it current form features 4 rows of 8 tactile switches and leds - the final version will add a fifth row of buttons and leds dedicated to control functions. It features an embedded hackduino, an 8-bit DAC option, an LM386 amp output, MIDI in/out/sync and is configurable to work with some of the most popular existing arduino audio projects. Firmware can be updated from the arduino IDE, either via an AVR ISP programmer, or by flashing the chip on an arduino board and swapping it out. Furthest along in its development is the Alpha firmware which features a 3 oscillator monosynth. Other firmware will include the Bravo which borrows code from the Bleeplabs Bleepdrum https://www.sparkfun.com/products/11606 , the Charlie, based around the Illutron 4-voice wavetable synth http://www.instructables.com/id/Turn-your-Arduino-into-a-4-voice-wavetable-synth-w/, and the Delta, based on the original Groovesizer with the auduino synth engine http://www.youtube.com/watch?v=9zsxWfsHDr4

Arduino Noise Maker

Arduino Noise Maker from James Taylor on Vimeo.
"First running complete circuit - similar to that of Little - scale on Blog Spot. This is actually the second version because we had massive problems sourcing the components needed, and we tried using a second Arduino board to clone the missing chips.

In this one however, the main noise is being outputted to the Breadboard via 6 lines into a 6 bit R2R DAC.

The schmitt triggers are mounted on a nuelectronics arduino board, which controls the vibrato and the wave selector units. The two extra pots on the breadboard are the pitch and speed selection pots.

Stay tuned for more - next version promises to have some midi integration!

Arduino controlled casio keyboards and samplers

YouTube via bubagoo | November 20, 2010 | 2 likes, 0 dislikes

"In this video I'm controlling 2 casio SK1s, a casio SA-38 and 3 SAW voice memo recorders with an Arduino. I've wired a bunch of the pushbuttons on the different devices to the arduino and have written some simple code to sequence it all.
-The SA-38 is useful because it has a pushbutton for each drum voice. By interfacing this with the arduino I'm able to write and play drum patterns.
-Then I wired up the "one key play" buttons on the SK1s. The SK1 lets you record a sequence then play it back one note at a time every time you hit "one key play".
-Finally I wired up the "record" and "play" buttons on 3 little voice memo recorders. These record sound from the keyboards and play it back. They're pretty noisy but add some nice variety to the overall sound.
The whole project was pretty easy and is very flexible, especially if you're a savvy arduino programmer. Tutorial coming soon to Make magazine."

According to Davide Mancini of soundmachines, the NS1nanosynth is the first modular synth for sale in the Arduino Store. Interesting little bit of synth history. If you search for synth in the Arduino Store you only get the NS1 and Ray Wilson's Make: Analog Synthesizers. A search for synthesizers only brings up the book. It's kind of interesting when you consider how many Arduino based synths and sound machines are out there.

"The NS1nanosynth synthesizer is tiny 220x85mm analog modular synthesizer coupled with an Arduino Micro platform.

NS1nanosynth is a good compromise between complexity and usability. It's a Maker synth, totally hackable and customazable yet a good entry level device, and on a budget."

"Great News, I'm BACK, and with a new project for the great Beat707 MIDI Drum Sequencer, fully Arduino compatible open-source.

What I will be working next is the new Beat707 2.0 set of PCBs, I will have more info about it soon. But the idea is to make the PCB with headers for buttons and leds, so the unit can have custom design. Let's say you want a 4 x 4 button + led grid, or a 1 x 16 grid instead. You can use the same boards. This way you can make a regular sized unit, or a big one like my latest XXL project was. I will no longer use touch sensitive buttons. Watch the videos below on how the previous Beat707 Drum Sequencers were, which were a great success already. The next unit will be fully open-source.

More details on the Beat707 2.0 PCB Boards Below, and also the specs of the hardware + software of the MIDI Drum Sequencer, fully Arduino Compatible. You can check, below, the old Beat707 XXL BIG PCB Board, as the new board will be based on it, but much smaller, making it possible to be used on small and large setups. I will also release some Acrylic cases designs later on.

But for all this to happen I need to collect some contributions in order to keep working on this and release new videos and software on how to create your own device. All in all I'm trying to collect $ 2,000.00 USD (specially for the PCB industrial upfront fees), which should be ok to do. In return any contribution will get you a free copy of Wusik 4000, a Virtual Modular Software Plugin for Windows and MAC, see details below.

The Specs for the Beat707 2.0 is a bit open now, as I plan on adding as much options possible using the "power" of the ATmega328 chip. The previous software had:

14 Drum Tracks (on/off steps)
2 Note Tracks (0~127 note number, off and glide)
2 Accent Tracks
32 x 2 steps for each Drum Track
Since the idea is to add the SD Card to replace both external EEPROM and FLASH, the number of patterns per song could be 127.

The new boards will come with the same design as the Beat707 XXL had, you can see a video of that board below. It comes with Arduino compatible ATmegas, so you don't need an actual arduino, just an USB to FTDI cable and you are good to go. After the board is fully programmed no computer is required for using it live..."

The pocket-sized drum machine and synthesizer, currently on Kickstarter, was prototyped using an Arduino Nano and will be fully Arduino-compatible when released. This means that in addition to changing the sound and interface around with readily-available sound packs—which include Theremin Bitty, Techno Bitty, Basement Bitty, Trap Bitty, Lofi Bitty, and Beach Bitty—it can be programmed with the Arduino IDE. The device can even run sound software written for other Arduino boards.

Bitty features four sample trigger buttons, a pair of knobs, and a speaker. Designed for entry-level EDM enthusiasts and studio musicians alike, you can play the drums and melodies manually, as well as trigger patterns to produce dance music or hip hop beats. These can be chosen via the left knob, while the right knob handles pitch, note selection, and arpeggiation."
