In this project we’re building a diy midi controller that works with ios devices and analog synths. Say hello to OONTZ, the open source button grid controller based on the adafruit trellis. The mini OONTZ is a 3d printed case housing one trellis and 4 potentiometers ideal for a 16 button drum pad. OONTZ works with any MIDI software and hardware. No more virtual midi or serial to MIDI stuff, oontz is legit USB MIDI.

Say hello to OONTZ, the open source button grid controller based on the Adafruit Trellis button platform.

This PCB is specially made to match the Adafruit 4×4 elastomer keypad. Each Trellis PCB has 4×4 pads and 4×4 matching spots for 3mm LEDs. The circuitry on-board handles the background key-presses and LED lighting for the 4×4 tile. However, it does not have any microcontroller or other ‘brains’ – an Arduino (or similar microcontroller) is required to control the Trellis to read the keypress data and let it know when to light up LEDs as desired.

A DIY experimental Synth made of MFOS, YUSYNTH and RANDOM MODULE
An overview of all the features on my “Teensy Synth”.
You can find the materials to make this synthesizer in the Arduino Projects section of www.brianpeters.net
Hear this synthesizer in action with 4 other chip-based synthesizers:
Homemade analog synthesizer, partly built with minimoog model d circuits. VCF circuit here http://www.diodenfilter.de, which produced the synthi sounds (and drumbox V1.0).
Selbstgebauter analoger Syntheiszer, teilweise aus Minimoog Modell D – Schaltungen aufgebaut. VCF-Schaltung hierhttp://www.diodenfilter.de, welches die Synthie-Klänge produzierte (und Drumbox V1.0).
We build our own full-size MS20, add a filter selection switch and compare with an original.
I built the MS20 Kit – one of only 1,000 available. Be sure to check out our full review coming soon. Music: Intellijel Atlantis through Behringer X32 with Vintage Room freeze reverb for pads, stereo delay.
The MS-20 Kit is a true-analog, 1:1 scale reissue of the MS-20, with both filters built in (the more aggressive early production filter and more mellow late production one). Every details has been replicated, right down to the packaging, which includes a letter from the original MS-20 engineers and the President of Korg, Inc.
The Korg MS-20 kit has a street price of about $1,400.
TTSH – ARP 2600 Clone Time Lapse Build. Track includs only sound from the finished TTSH, some additinal delay and eq :).
Martin Widmann documents his build of the ARP 2600 clone, the Two Thousand Six Hundred (TTSH) synthesizer. TTSH is based on the classic ARP 2600. It’s one of the nicest DIY projects and a a very complex build. The TTSH is available as a kit containing PCBs and front panel. Nothing is pre-built and no components are included, so you have to source your own parts.
The video is a time-lapse video, 36,852 pictures, taken every 5 seconds. The full build is shown, including: ttsh, midi interface, case, calibration & bug fixing.
The soundtrack was made with only the finished TTSH.

Peff has a new item out – a pulse wave oscillator called the oneTesla, here’s what he has to say about it:
For those who follow my social media streams, you may have already seen the various DIYAudio, DIYSynth, DIYrepair projects going on around here for the past year. One of these projects is the oneTesla Musical Tesla Coil kit. In “synth speak” it’s essentially a pulse wave oscillator. The oneTesla incorporates an arduino brain that receives MIDI note information, and the sparking plasma threads emitting from the coil oscillate at musical pitches. I certainly recommend the kit if you’re looking for a fun weekend project, however it may require some debugging and may also require the need for a function generator and oscilloscope. Over the past year it seems that the development team has ironed out the kinks in the design and even novices generally have great success in their builds.
The link below is an archive of the multisampled notes generated from the oneTesla. I’ve provided the archive as a folder containing an NN-XT patch. The audio was recorded at quite a distance from the Tesla coil, mainly because I didn’t want the coil to discharge through the microphone, but also because the output is incredibly loud. The recorded results aren’t as impressive as having the real-time audio-visual experience, so get a better “feel” of the actual sound, it’s recommended that you run the sampler output into a peak limiter and push the gain up 3dB to 9dB, and play the samples back at very high levels. The coil is sampled note-by-note from MIDI C0 to C5, and you will hear “spark” artifacts and a few obvious loop edits.
