"FOR USE WITH Roland SC-88 PRO, SC-88, SC-55 MKII, SC-55, SC-8850*, CM-64, etc. (*partial support only)

*Dust off and unleash the programming power of your venerable Roland SOUND CANVAS
*Press into service those fat and juicy Roland resonant filters
*Tweak all those pesky hidden effects parameters
*Easily dial in all those eminently routable continuous controllers for maximum expression and creativity
*Program unique sounds starting with the basic building blocks of the well-honed Roland GM sound sets
*Play all those old SMF files with a unique twist to your sounds, programmed by you
*These are just some of the things you can do with this new comprehensive Roland SOUND CANVAS programmer for Apple’s LOGIC DAW

This software is a virtual Roland Sound Canvas programmer for use with various Roland Sound Canvas synthesizers. It simulates a hardware programmer in a software environment within the APPLE LOGIC audio / sequencer program (formerly Emagic LOGIC). To use this software you MUST have a valid copy of LOGIC on your computer (see below) as well as a MIDI interface which connects your computer via MIDI cable to your hardware synthesizer (or you can use the built-in serial interface on some of these units). This software CANNOT be used as a stand alone application under any circumstances. It will not run in Reason, Ableton, AU, VST or any other plug-in format. It is created and presented through use of the LOGIC “environment” architecture.

This programmer is compatible with many different Roland SOUND CANVAS models to varying degrees. Completely optimized for Roland SC-88 PRO, it handles all possible editing duties in that unit with the single exception of micro-tuning, and the same for the SC-88. It will also support the earlier SOUND CANVAS models such as the SC-55 Mk II, SC-55, and a host of others using the GM standard and extras to the degree supported by your particular model’s architecture. This includes Roland’s PC computer products, Virtual Sound Canvas and many others - about 40 different units in all. Check this WIKI page if you want too see if your unit may be supported:

MOK Introduces Filtryg Professional Dual Filter Effect

MOK Filtryg Introduction

"MOK is excited to introduce Filtryg, a professional dual filter effect with deep sound sculpting features to aid in mixing, or add new dimensions in rhythm and timbre to recorded tracks. The integrated envelope follower, wide range LFOs, and MIDI keyboard tracking, each react to your playing as well as your source audio, forming an inspired filter effect that becomes a part of your performance.

The Filtryg dual filter effect plugin offers three filter types with a 12 dB State Variable Filter running in series or parallel with a choice of either 24 dB Ladder, or multiple modes of Biquad, each with their own personality and character. The State Variable Filter is continuously morph-able from Lowpass to Highpass filter modes, with either Bandpass or Notch in-between, while the Ladder and Biquad have a Drive control for extra punch and crunch on the output.

Filtryg’s visually striking interface offers a knob-based control surface, familiar to synthesists and effects users alike. The audio path, modulation routes, and their respective controls are all plainly visible and understandable from the front panel, enabling intuitive and speedy effect construction. It is possible to set up the harmonic-rich sound of audio rate filter FM, including assignable keyboard tracking, in just a few seconds. Finally, all of Filtryg’s parameters are available to automate from the plugin host.

Filtryg is compatible with AAX, AU and VST on Mac, PC and Linux, and is available now at


- Dual filter configuration in Series, Parallel or Mixed for flexible timbral shaping

- 12 dB State Variable Filter (LP, HP, BP, N), 24 dB Ladder Filter (LP, HP), and multiple Biquad Filter choices, each with distinct personality and character

- Morph knob morphs between State Variable Filter modes for dynamic filter variation

- Drive knob adds punch and crunch to the Ladder and Biquad Filter output

- Audio rate Filter FM enables unusual harmonic generation capabilities

- Keytrack modulation control for integrating keyboard performance

- Envelope Follower for direct interaction with input audio and sidechain pumping effects

- Tempo synchronized LFOs and threshold triggered Envelopes for rhythmic modulations

- Customizable color themes and language settings"

MB-6582 midibox sid - C64 - Enigma Force cover


"The theme from the sequel of Shadowfire recreated with the MB6582, a Boss DR550 mk2 and some supersaws to pad it out a bit.

Staying quite faithful to the original with all the modulated PWM stuff from the MB6582.

Another shout out to Fred Gray - the composer of the original C64 version.

Cheers to:
For hosting the scans that i used here :)

A fun one to do. The tune is great, and making the little comic strip recreation of the crashed shuttle opening screen bought a smile to my face :)"

See the X1L3 and Midibox labels below for more.

ESK - analog Drums and a Graphic Equalizer


"Got an old analog Rane GE60 Graphic Equalizer (2x 30 band with +/-12dB on each band).
So i thought to make a video that shows some nice sound experiments i can do with it.
I had 3 setups in mind:
1. Use the EQ as mono to stereo effect.
2. Use it as a kind of filterbank (+/-24dB on each band).
3. Add feedback and distortion to the filterbank setup.

All is done with a Arturia Drumbrute, a Rane GE60 EQ and in the last setup a Boss KM-60 mixer.
The Boss is wonderful for distortion sounds.

I’m always showing fist the clean signal from the drummachine and then with the EQ effect.

Direct recording without mastering."

Ahnyxian Sound Design:




"I was tasked with designing a JAWS themed pedal as part of a birthday gift for a true fan of the movie.
This is what i came up with:

- pedal allows to endlesly loop the iconic music theme,

- play an instrument over it,
- add a few randomly chosen quotes from the movie,

- alter the music track with manual or envelope controlled lowpass filter.
Ontop of that the pedal works as a stereo plate reverb and can be used that way with all the background sounds switched off.

Uses Teensy4 as it's main audio engine.
... and being a birthday gift, has a few hidden easter eggs :)"

WVR : modern, open source, embedded audio for $25

Currently on Kickstarter here.

Quick details via WVR:

"WVR is an ESP32 with a nice DAC and 8GB of fast eMMC memory. 18 stereo voices of simultaneous playback (at CD quality), which I think is something really needed in this space, in an open source project, at this price point.

The project also includes
a USB MIDI HOST add-on board,
a neat JavaScript library called RC.JS designed to help Arduino folks build GUI's, using React Native and Expo
the ability to store multiple firmware binaries in the eMMC, with the ability to boot from any of them
some tools to make building multi-sampled instruments a snap
2 dev boards
a stompbox version
etc, etc."

via the Kickstarter campaign:

"WVR is an open-source embedded solution for audio, with surprising capabilities. It includes everything you need to get started with embedded audio, with no soldering, and no coding necessary. WVR arrives ready to operate.

WVR is also a highly versatile device, capable of powering a new generation of embedded audio design, thanks in part to its wifi and bluetooth radio, providing all the power of a versatile and extensible Graphical User Interface ( GUI ), without the need for a screen or other interface. Users can upload samples, manage firmware, set configurations, build sequences, or control any other data imaginable, both wirelessly, and intuitively, using their laptop, or mobile device, inside a web browser, or even on a native mobile app on Android or iOS.


Playback up to 18 stereo wav files simultaneously, with ~1ms latency

Accepts virtually every audio file format, at any resolution, and any size, including wav, mp3, ogg, acc, flac, pcm, aiff, and many more

Upload audio, map samples to MIDI notes, configure pin functionality, apply FX, manage files, etc, all over WIFI, with the default firmware that WVR ships with, and without writing any code

Holds over 12 hours (8 GB) of stereo audio, at 16bit 44.1kHz resolution

Can buffer over 1.5 minutes (16 MB) of stereo audio in RAM alone, at 16bit 44.1kHz resolution
Optically isolated MIDI input, provides to-spec MIDI input implementation without any additional circuitry

14 GPIO pins, 8 of which can be analog inputs, and 4 of which can be capacitive touch inputs, plus the many peripherals available on the ESP32 .

WVR's Wifi can function either as a Station or Access Point (it can login to an existing wifi network, or can create its own network and accept connections directly from devices in range, without a router or local network of any kind)

write firmware in Arduino, and upload over wifi. Stores multiple firmwares onboard, selectable via the UI. Fully compatible with the extensive, and battle-tested ESP Arduino library, and the exceptionally powerful ESP-IDF framework.

use RC.js JavaScript framework to modify, or custom build, the User Interface that WVR serves to users, without prior knowledge of CSS, HTML, Babel, Node, etc. Even build and deploy native mobile apps for iOS or Android from the same code base. You can play with RC.js in this REPL, try modifying the existing code, to see how it's intuitive, and highly portable, component-based syntax works, and check out the file to learn more.

onboard Ultra Low Power (ULP) co-processor means WVR consumes only ~10uA in sleep mode

8knobsPortable synthesizer and midi controller. | Indiegogo

"8knobs is a portable synthesizer and midi controller. Right out of the box 8knobs creates drones and atmospheres (ambient soundscapes). 8knobs encourages learning synthesis, electronics, computer literacy and experimentation. Built on the popular Arduino platform it readily embodies the character of the user. It is an open source and hacker friendly instrument, ready to morph according to a wide range of use cases."

"8knobs can be used as a MIDI controller through usb, as a plug-n-play device; this means no installations, no additional convertors, no headaches. The 8knobs DIY kit consists of a PCB, an Arduino Atmega 32u4, header pins, potentiometers, all the necessary electronic components, mounting hardware, a laser cut wood veneer body and a case made of hand stitched jute with raw unbleached cotton.

8knobs has 1 audio out, MIDI over USB or MIDI over 3.5mm to connect to other traditional synthesisers. It can be powered via USB, DC 9-12v wall adaptor or a 9v battery.


// Electronics // Sound synthesis // Computer Coding

While building 8knobs you’ll learn everything from the basics like soldering to the fundamentals of sound synthesis, electronics and computer codes by understanding, engineering and experimenting with signal flow. Learn the art of signal flow by building your own custom synthesiser and controller for more experiments!


// Creative learning and new approaches

Getting familiar with signal flow unlocks a wide range of new opportunities to innovate and produce technical as well as creative applications in various media - both analog and digital.

Just like the flow of signals in the brain are interconnected and influence each other. For example, like neurons communicating information in both chemical and electrical forms, can result in infinite combinations of thoughts, words, and actions, similarly, playing with signal flow in hardware (electronics), software (coding) and space (acoustics) can result in infinite creative expressions.

The art of signal flow offers endless possibilities, and whether you take it up as a hobby or use it to pursue a life-changing innovation is for you to choose. Either way, it’s a great feeling to get your hands dirty in the energetic flow of signals and DIY culture!"

Isla Instruments S2400: Audio Engine & Analog Outs Comparisons


"Showing the lovely differences you get in the S2400 using the difference sampling / playback engines. A rough conclusion is: if you want super old-school alias-heaven, sample AND playback using the 12bit engine. If you want to back off from this slightly, sample using the 24bit engine but playback using 12bit. In addition, you can remove aliasing using the analogue output filters or, just use these for effect.

Pad 6: Sampled: ‘Hi-Fi’ 24Bit 48Khz
Playback: ‘Hi-Fi’ 24Bit 48Khz

Pad 7: Sampled: ‘Hi-Fi’ 24Bit 48Khz
Playback: ‘Classic' 12-Bit 26Khz

Pad 8: Sampled: ‘Classic' 12-Bit 26Khz
Playback: ‘Classic' 12-Bit 26Khz

BTW, YouTube makes these comparisons less apparent; in real life, the differences are maybe 25% more obvious."

16- The Arturia PolyBrute- The Matrix Part A


"Here is the first part of a two-part video exploration of the functionality of the matrix present on the Arturia PolyBrute. As it focuses on functionality, there is relatively little audio-related content or performance.

The theme for this demonstration was recorded by multitracking the Arturia PolyBrute in order to provide the various parts necessary. The drums were assembled out of loops from Apple’s GarageBand."

AutomaticGainsay Arturia PolyBrute posts Running Order V2 firmware update: ratchets, probability, Euclidean shift, live recording

"What is new in Firmware v2.0?

Release notes: v.2.0: 29.12.2020

Live recording: now you can record a new sequence by toggling the Track select switch to the side and the current sequence will continue playing until we enter the new sequence and switch back to the center.
Ratcheting and Probability in the Standard (a.k.a. Step Input) mode.
When in the record state: current’s track knob (Repeats I for Track I and Repeats II for Track II) sets the ratcheting amounts for current step (0 to 3).
Another track knob (Repeats II for Track I and Repeats I for Track II) sets the probablity of current step (1% to 100%).
Ratchet means that trigger fires per current step not once, but up to 3 times more (4 in total with original trigger).
If Repeats I/II knobs are not touched on enabling the record switch and entering the steps, then the probablity is always 100% and all the ratchets are off.
Once we move each of track’s knobs during the record state, we set ratchet and probability values for current step and if we don’t change the knobs – those values apply to the next steps. To remember probability / ratchet parameter in step mode, first set the parameter value and then press step button to lock the value to a current step and change the new one.
Offset and Probability in the Euclidean mode.
When in the record state: current’s track knob (Repeats I for Track I and Repeats II for Track II) sets the offset amount -8 steps in CCW to 0 to +8 steps in CW of the euclidean circle grid.
Another track’s knob (Repeats II for Track I and Repeats I for Track II) sets the probability 1% in CCW to 100% CW of triggers appearing.
Sync inputs even more improved. Sync latency reduced to 100 micro seconds. Once external clock is paused for longer than 1 second and then continues again, that acts as a sync on both inputs.
Bug fix: previously if Repeats knob was set to fully CCW, then the divider knob would not have any effect on the speed of the track with external clock applied."

Isobutane (meets Polyend Tracker) - Fifuci


"I was trying out a sample of my cat and some other guitar stuff I was recording earlier and this is basically it being tweaked live in the Performance mode.

My name is Martin but everybody calls me Iso. I'm based in Bratislava and been making music since I have discovered a program called Music on one of those old PlayStation 1 demo discs in 1999. Started to play live under the moniker Isobutane sometime in 2006 and have been pretty active since.

When I bought the Polyend Tracker, I was just curious. What really happened when I got it was beyond anything I was expecting. I really mean it. I realized that throughout the years I became very ignorant about the best thing when making music – the process of making itself. With all these music jobs I had, I teach myself to work quickly and effectively and absolutely forgot about how good the process of making a track really feels. The Tracker brought this back, slowed me down a bit, make me learn, make me think of composing and sound design and actually brought a huge chunk of fun and passion to the game. So thank you for making it, it is certainly a machine that brought a new fresh chunk of enjoyment to what I love the most." ❤️
"The video comes with a included downloadable track project for you to explore and try performing it your own way! Using our Blog Scene section, we will be sharing various artists profiles and their Tracker composed music with the community growing around it. Sharing is caring! Get the project of Isobutane – Fifuci."
