open e-drums - Open Source Drum Synthesizer with Teensy 3.2

Published on Dec 31, 2019 Ryo Kosaka


Single piezo pad, Dual Piezo pad, 2 zone cymbal, 3 zone cymbal
Compatible with YAMAHA's 3 zone cymbal(PCY135/PCY155)
Compatible with SoftPot, FSR and Optical(TCRT5000) type hi-hat controllers
Sensing with MUX(4051 and 4067)
Setting mode with LCD or OLED
Sensitivity, Threshold, Scan Time, Mask Time, Note Number can be set with each pad
Works with ESP32 and Teensy and AVR boards such as UNO and MEGA.

"open e-drums" is a completely open source electronic drum. Pads that can be produced with 3D printers, and midi converters are all open source hardware. Arduino code for sensing is also available. You can create your own e-drum from scratch, or add pads to the Roland and YAMAHA kits.

This project started by accident. At the time, I was a product design student who had used Arduino just a little. When I found a drum mania controller at a used store at a bargain price, I was somehow attracted to it and bought it. This is the beginning of everything. I took it apart and played with Arduino. I used a piezo for the first time at that time. I learned the delicate sensing ability of piezo. I realized the greatness of electronic drums such as Roland, Yamaha, and Alesis, which process the signals beautifully. I want to try it myself.

I didn't have any knowledge of programming or electronics. In other words, I have acquired a lot of knowledge through this project. For some people, this project is just a reinvention of the wheel. But it's a very meaningful project for me. As I proceeded with this project, I drew on the knowledge of many predecessors. Many of them keep information open. That's great. So I decided to publish this project as an open source hardware project. I would be happy if this project helps someone create something."

New Mini Roland System 700 LAB Eurorack Clone by OMNiSYN

[000] OMNiSYN System 700 LAB Demo Published on Dec 21, 2019

"Clone of the Roland System 700 LAB"

This one was sent in by John L Rice.

OMNiSYN is a new maker as well. No additional info at the moment. It does look appear to be 3U eurorack of course.

You can spot three 702F oscillator modules on the far left for each row. A 703M Filter on the top and bottom rows, 705B dual ADSR envelop in the middle row, a Mixer in the middle row, and a few other modules.

Update via OMNiSYN in the comments:

"All modules (bar the 717 sequencer) are prototyped - prices would be comparable to to other manufacturers, but these are all dependent on availability of parts (some are custom and long lead time). Some videos on the full Roland System 700 clone are coming soon - stay tuned."

"All modules are 3U/12HP or 3U/18HP, case is 9U/60HP with 1A PSU and expansion port built in. All signals are brought to the front panels as was true in some of the original modules. Some modules have been expanded as in the mixer is now 2x 3 input and most modules use NOS original components. Hope this helps."

The original Roland System 700 Lab came with the following so this seems to match: 3 VCOs, 1 VCF, 1 VCA, 1 LFO, 2 ADSR EG, Noise (white & pink), Ring Mod, S/H and a Mixer.

Below is an image of one from the RL Music website. Apparently the signal path was normalized so you could play it minus cables like an ARP 2600. I'm guessing the OMNiSYN eurorack version consists of independent modules and is not normalized.

"This is a very powerful 3 oscillator normalised system with 1/4 inch jack In/Out for expanded sound creation possibilities and is based entirely on the system architecture of the full System 700."

Playing live with nuclear instruments and unknown synths

Published on Dec 16, 2019 HAINBACH

Some new gear in the second half of the video includes the Herbs and Stones Liquid Foam and the Neon Egg Planetarium (demos below).

"In which I play an improvised live show with a setup that is new and barely rehearsed.

Usually when I play live, I like to work with the setup I have had for the past three years. In fact, the reason for this channel was that I needed an audience to get better at improvising on my instruments, the camera became an important tool to get good it. But after five weeks of doing art projects, theatre soundtracks and live performances I was burned out. So I decided to play myself a little bit - I choose a completely new setup. Only the Plumbutter was with me on stage before, the rest, including FX and mixer, are studio pieces. Some, such as the Boxcar I had never used in that function before, and one synth had just arrived that day. I did not even know if I could safely travel with the nuclear instrumentation modular rack, without it breaking. The excitement of trying something new helped break the block I felt and I had a good time at the show.

You can find the full audio here:"

Orpho Vollrausch | Vacuum Tube VCO / Noise Generator Eurorack Module

Published on Nov 26, 2019 HOX808

"The Orpho Vollrausch generates its sound through two Russian military tubes (6SH1P)."

Google translated from Orpho:

Vollrausch | Vacuum Tube VCO / Noise Generator

The Orpho "Fullrush" is a combination of Tube-VCO and Noise Generator. It is a non-standard VCO module designed primarily as a noise generator. Two Russian military tubes (6SH1P) are used. The noise can be mixed in with a scope controller. When the noise component increases, the frequency of the oscillator varies until it is completely full. If you reduce the noise completely, the pure VCO signal is left over. Due to the "curved" characteristics of the tube oscillator, the module does not have a precisely defined control characteristic (e.g., V / octave). The inevitable tolerances of the tube oscillator will also make each module sound a little different. The tubes can also be replaced by two EF95 or similar. be exchanged, which then sound different again. By applying a control voltage to the CV input, e.g. LFO, sequencer, etc. can be varied in the usual way the sound varied.


This is the first Orpho post on MATRIXSYNTH.

1979 SMP Overview

Published on Nov 19, 2019 Todd Barton

"My initial encounter and overview with 1979's Stereo Microsound Processor (SMP) based on Mutable Instruments Clouds but styled with added features for the Buchla format. A later episode will have some sound demos.

Purchase information:

A good Clouds tutorial for the curious: [posted here]

Consider joining my Patreon page to support continuing tutorials for Buchla, Serge, Hordijk and some Eurorack:"

Update: Note 1979 is the brand, not the year. I created a new site label for them. I believe 1979 is Wes Milholen of Grayscale's brand. You can find a 20Objects interview with him here.

The SMP / STEREO MICROSOUND PROCESSOR is currently priced at $850.

"Granular synthesis for 4U systems. Based on Clouds by Mutable Instruments, the SMP is a realtime granular synthesis processor that expands significantly on the original. Dedicated controls for previously hidden functions, additional CV inputs with inverting attenuators, easier access to preset recall and sampling settings, and increased control over output gain make this one of the most full-featured hardware granular processors available. It's a powerful addition to any Buchla-format system, offering a form of digital signal processing not previously available in this format."

Audio Interface with 4 audio input jacks and 4 audio output jacks. Daisy-chain function where the audio inputs are routed and mixed directly to the audio outputs.

About the Chameleon System

The Chameleon System consists of a hardware module, a Chameleon, that can be flashed with software files to decide its functionality.

There are two types of Chameleons:

This is a module equipped with a MCU as well as an audio shield. This module is for files that handles audio input or output, such as oscillators, filters etc. So far I've written these files:

• PANTHER Digital Synthesizer Module.
• NAMAQUA Four Oscillator Module.
• TIGRIS Stereo Filter Level Shaper.

ARM Cortex-M4@180MHz, 2-channel audio I/O, 3xC11D I/O, 3xGate I/O, TFT 2.2"-screen, Four potentiometers, One rotary encoder.

This is a module equipped with just a MCU. This module is for files that handle data manipulation, LFOs, envelopes etc. So far I've written these files:

• NAMIBIA MIDI Input/Output and Data Randomizer.
• JACKSON Quad Function Generator.

ARM Cortex-M4@180MHz, 4xC11D I/O, 4xGate I/O, TFT 2.2"-screen, Four potentiometers, One rotary encoder.

Power is supplied to a Chameleon connected to power via its USB-port.

The Chameleons communicate with each other using standard 3.5mm cables sending and receiving 11-bit data. I call this technique C11D or Controlled 11-bit Data as a digital equivalent to CV, Controlled Voltage. Values between 0 and 2048 are sent and received. A unipolar parameter subtracts 1024 from the incoming value making it possible to modulate between -1024 and 1024.

The four analog potentiometers on each module work as controllers for real-time control of key parameters.

PCB DIMENSIONS 100x100mm."

Soundmit 2019: Lab4Music Enjoy MIDI Controller

Published on Nov 4, 2019 Ask.Audio

Priced at 299 Euro.

"Here's a MIDI controller which looks different to almost every other one out there on the market, plus it has a joystick and some innovative features. What's not to like?"

Manages MIDI pitch and control change thru USB port.

Analog Soul
Generates analog CV, LFO, PITCH, GATE, TRIGGER.

Up to 10 presets programmable via web interface.

enJOY is a controller that combine analog CV world with digital MIDI world. The front panel is dominated by the joystick lever, while the rear panel contains three input jacks (two for expression type pedals, one for sustain type pedals), three output stereo jacks (6 analog cv) and one usb type B socket.

Digital Side: Enjoy is a USB class compliant MIDI device. You can use it with your USB-MIDI host like Sipario or a PC, without the need of any driver. Once programmed you can use it stand alone and generate MIDI pitch and control change (expression, volume, filter cutoff, etc.) by moving the joystick or pedals.

Analog Soul: four of six analog outputs can generate cv, gate, pitch and trigger, two outputs can also generate lfo. All CV's can be modulated by joystick, pedals or from MIDI messages like control changes coming from USB port.

Web: To program the device just connect by browser to on the program section and set the parameters. There are ten memory locations, selectable by the web application, with which switch to various the configurations. It is also possible, using the button, to scroll through the first three presets without using the browser.

> MIDI-USB: control change generator according joystick and pedals movements.

> MIDI-CV: control change remapping according incoming CC form USB external device to Control Voltage outputs (-4.5V +4.5V).

> MIDI-CV: MIDI note messages conversion to PITCH, GATE and VELOCITY signals (0V +5V).

> MIDI-CV: MIDI System Real-Time messages conversion to TRIGGER signals (0V +5V).

> CV: Control Voltage generation modulated by joystick or pedals (-4.5V +4.5V).

> CV-LFO: sine, square, saw, tringle LFO generation, with AMP and FREQ modulated by joystick or pedals (-4.5V +4.5V, max 100Hz).

SOUNDMIT 2019 Lilla Midi Expander

Published on Nov 2, 2019 BAMTV

"The Lilla midi expander is currently a prototype/hobby project. It is based on the Teensy 3.6 microcontroller which has powerful features. The code is open source, the machine has an eurorack format but is controlled by midi. Lilla’s controls features 12 rotary encoders and 8 pushbuttons and includes MIDI in, MIDI thru, and stereo out. Via the SD card it can load samples, layered across the keyboard, and those can be changed with pitch and envelopes. It plays back with 8 voice polyphony. It also has effects like distortion, bit crusher and compressor on board.


"Lilla is an open source project for a polyphonic midi expander, based on Teensy 3.6 microcontroller. Lilla includes:


n.1 Teensy 3.6 - overclock 240MHz
n.1 Teensy Audio Adaptor
n.1 flash memory chip W25Q256FV (32Mbyte serial flash memory)
n.3 CD74HC4067 (16-Channel Analog Multiplexer)
n.1 128x160 TFT color display
n.1 HCPL260L (single-channel optocoupler)
n.1 CD4093B (quad 2-Input NAND Schmitt Triggers)

n.12 rotary encoders with pushbutton
n.8 pushbuttons
Teensy program pushbutton
i/o interfaces:

midi in (DIN)
midi thru (DIN)
stereo line output
micro-SD socket

reading files from flash memory: 8
reading files from RAM: 12
Audio files and presets

Lilla uses 44.1kHz 16bit mono .RAW (header-less) audio files, imported from micro-SD card. Lilla can store up to 100 Sounds; a Sound is described by these elements:

an audio file
interval to be played (first sample A - last sample B): from 100 samples to full length
play mode: A -> B, B -> A, loop A -> B, loop A <-> B, loop B -> A, loop B <-> A
fine tune
ADSR parameters
Attack ramp: fast, slow
Audio file is played from flash memory until the interval to be played contains more than 675 samples. Below 675 samples, audio is played from RAM: in this case, an automatic pitch-correction keeps the sound in tune with the standard tuning (middle C: 261.6Hz).

Lilla can store up to 30 setups called Sessions; a Session is a group of up to 8 Instruments; each Instrument is defined by:

a Sound
keyboard span (first key - last key)
keys mode: momentary, hold
In a Session, all 8 Instruments can also be layered on each other.

noodlebox serendipity sequencer prototype by six4pix

Published on Oct 24, 2019 While We Were Sleeping

00:00 - noodlebox on
00:05 - Fist noodle - My first go on the noodlebox. part of an Instagram live video.
02:39 - Two Layers - An example of one layer modifying another (details below)
03:12 - In the six4pix studio - Jason showing me around the noodlebox. You will be joining us mid-conversation and It's just to give an idea, not a tutorial.

noodlebox Details:
My good friend Jason gave me a noodlebox prototype so I can help test it :)

In the video, I have the noodlebox MIDI synced to my MPC Live and sends CV and Gate to control a bassline on my eurorack.

The software for the noodlebox is at an early stage and features and functionality can change.

noodlebox Layers:
The noodlebox is a 4 layers sequencer where layers can be though of as tracks. each has an individual midi channel and CV/Gate. Layers can be used to modify each other (Like transpose example at 2:39). Layers can have their own signatures and length. You can drag the start to end points in both directions to create a loop of varies length and directions.

noodlebox pages:
Each layer can also have 4 pages (versions) that can be stringed together at any order and number of repeats (like a song mode)

All this and other features can be used to noodle together vary complex and long patterns.

More Videos details
in the two layers examples 02:39 we use 2 layers each with a 4 note pattern.
The first playing a simple 4 note pattern.
The second also 4 notes long but at a slow clock division, transposing the first layer.
We are using the trigger of the first layer to trigger the VCA envelope and the transposed CV from the second layer to control the pitch.

DIY analogue synthesizer jam

Published on Oct 14, 2019 SpamSundays

"Here's a project that I've been working on for a long time now. It has two AS3340 based VCOs, outputting either ramp or square wavefroms that can be mixed together the latter of which having a pulse width control knob, which can be modulated as well.

Other circuits include a simple VCA and an envelope with attack and decay controls, a resonant VCF and an LFO with sine, triangle and square waves. I also included a real tube distortion running at 120 volts B+ (non of that starved plate BS) to add some more harmonics to the sound. As a final touch I added a third 555 oscillator which can hard sync both VCOs for some more fun.

PWM, filter cutoff and the hard sync oscillator all can be modulated to make some absolutely crazy sounds.

Here's a patch I threw together with the Korg SQ-1 and some reverb coming from the Zoom MS70-CDR.
