Our range of 3U professional MIDI controlled analogue modules continues to expand with four new products. These are all in an advanced development stage and the order of release will be according to interest and demand. For further information please use the contact form.
With many 3U modules now using MIDI they may be directly connected with internal cables or brought out to panel connectors. Maximum flexibility for connector types, position in case, and routing is provided by Molex KK 0.1" headers on the pcbs.
"What fits in your pocket, is fully Open Source, and can run CircuitPython, MakeCode Arcade or Arduino games you write yourself? That's right, it's the Adafruit PyGamer! We wanted to make an entry-level gaming handheld for DIY gaming, and maybe a little retro-emulation. It's not the fastest and best of everything but it is an all-in-one dev board with a lot of possibilities!
The PyGamer is powered by our favorite chip, the ATSAMD51, with 512KB of flash and 192KB of RAM. We add 8 MB of QSPI flash for file storage, handy for images, fonts, sounds, or game assets."

"Here's a nice, restored ARP Omni 2... with MIDI!! This synthesizer has just been fully serviced by Synthchaser, the United States' top ARP specialist - recapped, new key bushings, new LED sliders, clean, fully functional, calibrated, in tune and sounding great. And best of all, this has been fitted with the Synthchaser MIDI Adapter! This keyboard is the sound of Joy Division and is all over The Cars' "Moving In Stereo", and many other late 70's/early 80's albums. It produces the lush Solina/String Ensemble sounds plus has a polyphonic synthesizer section with a voltage controlled filter, LFO, and ADSR, and a dedicated bass synthesizer section.
Excellent condition, with some marks on the right leather side panel. Includes a road case that needs new foam and to be aired out as it smells musty. See photos for condition. This synth was serviced by Synthchaser (the top ARP specialist) in February 2026. Work done included:
Synthchaser MIDI Adapter - Supports MIDI IN and THRU (only an "IN" jack has been fitted on this synthesizer). Configurable MIDI channel and starting key on your MIDI controller.
Synthchaser Precision LED slider upgrade. All 15 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders (purple color--think Prince!). The difference in the way these sliders feel and perform compared to the originals is a huge improvement.
Power supply rebuilt - All tantalum and electrolytic capacitors in the power supply have been replaced, and high quality, high temperature 105 deg C capacitors have been used for the power supply filter capacitors.
All tantalum capacitors replaced - The tantalum capacitors in ARP synths are ticking time bombs. All of the over 100 tantalum capacitors in this synth, including the power supply and filter submodule, have been replaced with electrolytics to help provide stable operation for years to come.
Synthchaser 4075 Filter Enhancement Kit Installed - The ARP Omni uses the same 4075 filter submodule found in the Odyssey, Quadra, Avatar, and Pro DGX. This has been recapped, and enhanced to provide superior frequency response.
Keyboard rebuild - New key bushings installed, buss bar & key contacts cleaned and adjusted, keybed leveled, keys cleaned
Oscilloscope calibration - Fully calibrated to factory spec using oscilloscope and frequency counter."
"We head to the Melbourne Electronic Sound Studio for our first hands-on look at the KORG Berlin Phase 8, one of the most unusual instruments to land on the Noisegate desk in years. Phase 8 is built around eight electromechanical voices, each physically striking a steel resonator or tine. Instead of traditional oscillators, sound is generated through real vibrating materials, then shaped with envelopes, modulation, sequencing, and analogue wavefolding. The result feels closer to playing a physical instrument than programming a synth.
In this video, we explore: – How Phase 8 produces sound – Sequencing, pluck, shift and performance controls – Acoustic interaction using everyday objects – Processing Phase 8 with external effects – Integrating Phase 8 into a wider live jam setup
CHAPTERS: 0:39 – Why Phase 8 Is Different 1:04 – What Is Acoustic Synthesis? 1:40 – Touch, Feedback & Physical Interaction 2:13 – Tuning, Scales & Resonators Explained 2:32 – Playing Phase 8 Like a Synth 2:41 – Per-Voice Envelopes & Velocity 3:11 – Air Slider & Raw Pickup Sound 3:35 – Shift & Pluck Performance Controls 4:27 – Sequencer Overview & Storage 4:56 – Playing a Recorded Sequence 5:06 – Step Recording & Polyrhythms 6:21 – Interacting with the Tines Physically 6:30 – Using Objects to Change the Sound 7:50 – Light vs Heavy Materials on the Tines 8:26 – Percussive & Prepared-Style Sounds 9:47 – Modulation & Tonal Experimentation 9:56 – Processing Phase 8 with External Effects 10:14 – Finding Sweet Spots with FX 10:27 – Connectivity: MIDI, USB-C, CV & Sync 10:58 – Hybrid Setup with OP-XY 11:24 – Live Jam Begins 14:29 – Reflections on Exploration & Sweet Spots 15:31 – Why Phase 8 Rewards Time & Touch 15:36 – Trying Phase 8 at MESS 16:04 – Final Thoughts & Sign-Off
We also look at how Phase 8 plays with other gear, including Teenage Engineering OP-XY and outboard effects, and why finding the “sweet spot” is such a big part of the experience."
"‘Bizarre Love Triangle’ from 1986 is first off the rank for my ‘New Order February’ recreations.
I love this perfect slice of dance-synth-pop and I was keen to get the DX7 bass intro as close as I could. Earlier this week I’ve been showing the tiny $75 Raspberry Pi synth, MiniDEXED, that I built to add this vital ingredient. If you are interested check out the video showing more details,
• I made a synth for $75* ! (*excluding tar... [posted here]
A couple of very clever folk identified what I was cooking up!
The MiniDEXED was sequenced from the MIDI tracks on the Circuit Tracks and routed into the audio in to add effects from the Tracks. All that you hear was programmed into the single Circuit Tracks and no further additional synths or processing were done to the sound – it’s straight audio out recorded direct into a Zoom L6.
The arrangement was taken from several versions posted on Musescore and compressed into the 4 melodic tracks and rhythm. Thanks to everyone who posts their transcriptions there.
I hope you enjoy the track as much as I did making it. Stay tuned for more New Order recreations and reworkings for the rest of this month.
(Ableton Move version coming in just a couple of days...I'll post a link here when it's live).
📡 'Quantum Pulses' is a bank of 50 presets + patterns for the U-he Zebra 2 virtual synthesizer. The collection contains dark, deep, atmospheric, sci-fi, harsh and aggressive sounds that have a wide range of uses: from cinematic sound design to modular techno sequences. 🔠The soundset is inspired by the modern techno scene, vintage sci-fi films and experimental robots. Perfect for Techno, Industrial, Dub, IDM, Experimental, Cinematic sound design, and others.
⚗️ The sequences work in arpeggio mode, which allows for more interesting playing of several notes in a pattern. 🎚️ Each patch is performance-ready, with velocity sensitivity and ModWheel assignments mapped for expressive control. ModWheel affects the ADSR's performance, making sounds both clearer and more blurred.
🎛️ Each patch includes 8 Macros. These controls are designed stylistically and affect the waveform, giving it movement and changing its shape, adding various FM textures and bitcrush, and also affecting the filter by opening and closing it. The X/Y controls can be manipulated with a mouse or used as 1–8 macro knobs for hands-on control via a standard MIDI controller, making the soundset highly expressive and performance-friendly.
"In this noisy and deep track, I use all four tracks from Kaleidoscope.
Tracks 3 and 4 are two bass sounds, tuned to a common MIDI channel to work in unison. Their frequencies are shifted by a fifth and an octave. I change this interval as the track progresses. These sounds FM-modulate each other and themselves. They also have different glide values so that when the frequency is changed, the FM synthesis produces more fat and dirt. I also added distortion after the comb filter to make the sound as thick as possible. I was inspired by LORN.
Track 1 is a kick drum built on pitch modulation of a sine wave. This sine wave can be mixed with noise from a wavefolder. The modulation envelope increases the distortion level. The kick drum also has a very high feedback value of the comb filter, so we hear multiple echoes that act as a source of FM modulation for this kick drum. The comb filter's delay length is adjusted so that the echoes are precisely timed. The kick drum's filter is slightly closed to reduce the noise level.
Track 2 is a solo lead that has no internal modulations—just a sawtooth. However, it does have a cyclical volume envelope, which adds dynamics. This volume envelope also opens the kick filter on track 1, letting noise into the mix that feels like percussion. Track 2 experiences the FM modulation of track 3, which significantly complicates the timbre. I use this track for melodic movement—I play around with the transposition and try to keep the sound from becoming too dissonant.

This time I've used open-source hardware and software designed around the MT32-pi project. See link here, https://github.com/dwhinham/mt32-pi
There's a very excellent detailed build and demo video from @mr_floydst here,
• MT32-Pi DIY synthesizer: bare metal 80s no... [below]
Oddly the hardware worked out cheaper (despite a bigger display) as this is a commoner target build.
This excellent project uses any Pi from the Pi Zero 2W upwards to recreate a multi-timbral emulation of the Roland MT-32 synth and also act as a player for soundfonts in the .SF2 format.
I used a pre-assembled hardware kit from Ebay with a Raspberry Pi Zero 2W (with header). The assmbled complete hardware can also be bought from sites such as Etsy etc."
"This week, let's build and take a look at the #MT32 PI, another "bare metal" synthesizer running on #RaspberryPi. This is an emulator for the late #80s Roland MT-32 sound module, which was used by a lot of games for their sound track. The MT-32 PI can also load soundfonts, so you can use it as a ROMpler in your setup. Table of contents:

I ordered mine pre-built from Ebay - but that's just a reflection on my soldering skill!
To run the software it also needs a Raspberry Pi Zero 2 (buy one with a 'GPIO header' as then it's just plug and play once you have loaded the software from the above link). Make sure it's a 'Zero 2' as the older model is much slower.
Much more detail and slicker presentation here....
• MINIDEXED - honey, I shrunk my DX7 collection [posted here]
All of the above work was inspired by the very excellent and similar MT32-pi project by Dale Winham which emulates the Roland MT-32 synth and others. I've got a 2nd Pi Zero 2 and some parts in the wings for a further video...."
"The Wee Noisemakers PGB-1 (https://weenoisemakers.com/pgb-1/) is a credit‑card‑sized groovebox — but as we all know, size doesn’t matter. With 16 tracks, 16 patterns, and a song editor to tie everything together, you can create music not only with the internal synths and samplers but also with external MIDI gear. In this video, I try to give a solid overview of what to expect, though I don’t go into every detail. If you have questions, feel free to post them in the comments and I’ll do my best to answer.
For this video, I was provided with a review unit. Other than that, no money was exchanged.

"Torso Electronics presents the third live session recorded at our office space in Copenhagen.
In this episode, percussionist and sound artist Lorenzo Colombo presents an electroacoustic concert featuring the T1 and S4 in a hybrid setup combining metal percussion instruments and solenoids.
The performance is driven by the T1, used as both sequencer and live MIDI keyboard. It controls the SOMA Pulsar-23 and a set of dadamachines solenoids. The solenoids hit a set of Kolberg percussion bell plates, which function simultaneously as acoustic instruments and conductive metallic surfaces. Through body-resistance and circuit-bending interactions, these plates influence electrical signals and directly modulate the Pulsar-23 as well as generates MIDI that control the same instrument . All audio is routed into the S4, used as the sole sound-shaping and modulation unit.
