"TAL Sampler (using Loopop's Oberheim TEO 5 sample library) + Baby Audio Tekno.

Bass Station 2 as a MIDI controller and using its onboard arpeggiator, controlling TAL Sampler. I loaded a pluck patch, from Loopop's Oberheim TEO 5 synth sample library, running through an Akai S100 style DAC in TAL sampler, to give it an even more vintage/lo-fi feel.

Lastly added an analog style delay to the synth arp via Valhalla Delay. There's also a shaker loop on top of Tekno, also using Valhalla Delay (on the phaser setting). No external FX on Tekno."

Gintronic Transparentsea — MIDI Stereo Multi Effect Electronic Ambient Exploration

video upload by A Last Picture From Voyager and ginTronic

"In this video, I explore the Transparentsea, the first MIDI stereo multi-effect tabletop unit designed by Gintronic. More than a demo, I’m letting it breathe inside an electronic ambient setup, allowing it to shape space, stereo width, repetition, and slow transformations over time.

Sometimes it’s barely there. Sometimes it pulls the whole piece forward.

I also explore how it behaves in a real musical context, not as isolated effects, but integrated into evolving ambient compositions.

I’m always searching for tools that don’t just process sound, but create movement within it. The Transparentsea lives somewhere in that in-between space, between rhythm and atmosphere, control and drift.

Folktek Mescaline + Leploop: Psycho-Conga Line

video upload by Infin-D

"Here's something you don't see everyday. The Folktek Mescaline and the Leploop are both analogue "groove boxes", but of vastly different character. I took it as a challenge to get the dreamy, spacey Mescaline paired with the techno-industrial Leploop, and came up with this crazy Cuban-style rhythm.
The Mescaline sends a clock signal to the Korg SQ-64, which Midi-clocks the Mescaline. The Bastl Wave Bard adds some sampled percussion to the mix, delay provided by the Korg NTS-1. Due to the vast distance, I had to use a bread board to bridge a couple of triggers from the Mescaline to the Wave Bard.

At 7:16 I inadvertently tweaked the Leploop's percussion voice into self-oscillation, sorry if it snaps anyone out their trance.

Recorded live on the Zoom L6, audio normalized in Audacity.

"KOSMOS – A Compact Generative Sequencer Driving the Prophet‑5

This short clip features KOSMOS, my standalone generative MIDI sequencer, controlling a Sequential Prophet‑5. KOSMOS creates evolving melodic patterns and rhythmic variations in real time, while the Prophet‑5 provides its unmistakable analog warmth and depth.

The performance is completely autonomous — no DAW, no external processing — just KOSMOS generating the sequence and the Prophet‑5 responding with its classic tone.
It’s a small glimpse into how KOSMOS interacts with hardware synths and how expressive the pairing can be."

Knobula Monumatic, polyphonic modular synthesizer

Våld Labs Tresse: a multiengine synthesizer based on Plaits, for desktop.

video upload by Våld Labs

This one was sent my way via Meska who had the following to say: "It's 'basicaly' a standalone MI Plait with 3voice and extended oscilator models."

Video description follows:

"Tresse — 3-voice polyphonic desktop synth, 38 engines

Hey all,

Been working on this for a while and it's finally at a point where I want to share it.

*Tresse* is a standalone polyphonic synthesizer built around Mutable Instruments' Plaits DSP code, running on an ESP32-S3 with a custom PCB. Three voices of polyphony, 38 synthesis engines, USB, DIN/TRS and Bluetooth MIDI, and perhaps Ableton Link and our upcoming stack (VMB) Våld Modular Bus, expected to ship this summer, and which will a new wireless comms protocol with negligible latency, auto discovery and machine mesh capabilities (to be released soon).
Also enough knobs and encoders to actually play the thing without menu-diving, and a battery for when you're bored outside of your studio.

*The core idea:* take the full Plaits engine library — all 24 algorithms — and make it polyphonic in a self-contained hardware instrument. Then keep going and add 14 more custom engines on top.
There are hundreds of options similar to this in modular systems and i thought why not bring all these god-level creative tools to bedroom, desktop producers who don't have the money or the space (or will) to mingle in the modular space, and bring them one contained box with all they need.

What's inside

*ESP32-S3* doing all the DSP across both cores (voices 0+1 on Core 1, voice 2 on Core 0, parallel render)
**PCM5102A DAC**, 24-bit output, 32kHz sample rate
*4 pots + 4 rotary encoders* through CD74HC4067 mux and MCP23017 I2C expander
*OLED display* (128×64) for patch info, engine select, preset browsing
*USB MIDI + BLE MIDI* — works with everything, no adapter needed for wireless
Custom PCB, all through-hole friendly

38 engines

The first 24 are straight from Plaits — East Coast, Phase Distortion, all three DX7 variants, Terrain, String/Chords, Chiptune, Wavetable, Speech, Swarm, Particle, the Rings modes, the three drum engines, etc.

Then 14 custom engines built from scratch:

*Karplus-Strong* — proper physical string modeling with excitation morphing (noise → impulse → tonal)
*ByteBeat* — 8 classic formulas with pitch-tracked rate, gets wild
*CZ Phase Distortion* — Casio CZ-style, three distortion shapes
*Supersaw* — up to 7 detuned saws with PWM, the obvious one but it needed to exist
*Formant* — vowel synthesis with 3 bandpass resonators, gender shift control
*2-Op FM* — clean FM with 13 ratios and operator feedback
*Wavefolder* — sine/tri/saw/square source into a proper folder with bias
*Noise Drums* — SVF-based with pitch envelope, covers kicks through metallic hits
*Modal Resonator* — 8 tuned bandpass partials, morphs from harmonic → bell → bar inharmonicity, with a bowed excitation mode
*Sympathetic Strings* — 3 coupled Karplus delay lines with controllable coupling and interval ratios
*Comb Resonator* — 4 parallel comb filters with spread control
*Drawbars* — organ-style additive with 8 Hammond-ratio partials
*Complex Oscillator* — FM into wavefolder, Buchla-adjacent territory
*Grain Noise* — granular noise with smoothing, good for textures and pads

Controls

Three parameter layers accessible via toggle buttons:

*Normal* — Timbre, Morph, Harmonics, Color on pots; Attack, Decay, FM, LFO Depth on encoders
*MOD* — Fold, Detune, Ring Mod, Chorus on pots; LFO destination/shape/speed/sync on encoders
*SHIFT* — Filter Cutoff/Reso/Env/Type on pots; Portamento, Octave, Vibrato depth/speed on encoders

Hold both buttons → engine select overlay. Double-tap MOD → system menu (randomizer, MIDI config, play mode). Double-tap SHIFT → preset browser across three banks (own patches, generated, branches).

Play modes: Poly, Mono, and chord modes (Major, Minor, 7th, Sus4, Power, Octave).

The randomizer is one of my favorite things — it generates random patches with procedural names (stuff like "Velvet Moth" or "Iron Shard"), you scroll through them with the encoder, and save the ones you like to a generated preset bank. 512 slots each for generated and branch presets, 128 for your own.

What it sounds like

Honestly covers a lot of ground. The Plaits engines already span everything from classic analog to FM to physical modeling to noise, and the custom engines fill in some gaps I wanted — proper supersaw, real Karplus-Strong, the modal/sympathetic stuff for metallic and evolving tones, and the ByteBeat engine for when you want to go full chaos. The global FX chain (filter, wavefolder, ring mod, chorus) ties everything together.

The project should be available from April 2026, in kit or assembled units! Price to be discolsed once i have the final FINAL prototype, but shouldn't hurt the wallet.

This is a *Våld Labs* project from Lisbon Portugal. Much more to come.

Would love to hear what people think, and happy to answer questions about the build or the DSP. Be aware that this is a pretty advenced prototype, but still a prototype"

Note they also have the Consequencer pictured left but no additional info aside from the following on it yet.

CubuSynth also has a Consequencer announced back in 2024, but they appear to be unrelated.

Experimental Modular Footwork with TENORI-ON | Roar 2026-02-14 by atnr

video upload by atnr

"An experimental footwork piece created with YAMAHA TENORI-ON and a modular synthesizer.

In the modular system, Plaits serves as the main oscillator, while MIDI triggers the Quad Function & Trigger Source. The sound is split into two paths: the direct output of Mutable Instruments Plaits and a version processed through a Clouds clone. These two signals are mixed in stereo. The final output is routed through ‪@ChaseBlissAudio‬ LOST+FOUND, adding reverb and delay.

On the TENORI-ON, rhythm patterns are programmed in real time, with occasional delay applied via MOOD MKII."

GreyScale – A Standalone MIDI Sequencer KOSMOS Powered by Raspberry Pi Pico (RP2040)
