video upload by GuitarML

"*OPEN SOURCE* https://github.com/GuitarML/TouchedOu...

Demo of the Touched Out Sampler, which is a mod to my TouchedOut Synth. It adds a MAX4466 microphone to transform it into a chromatic sampler! The new code is open source under the 'sampler' branch of the TouchedOutSynth. The mod requires two 100uF capacitors and a 100 ohm resistor, along with the microphone. The Sampler is separate firmware, but repurposes the controls for recording and trimming samples, and looping."

ellitone tap-ki - a percussive note midi controller

video upload by ellitone instruments

"now available at ellitone.com

The ellitone tap-ki is a ‘percussive note’ midi-controller that features 12 highly-sensitive “tap touch” wooden bars. Formally known as the KeyControl 2, the ellitone tap-ki found its true name and brings back all of the same functionality in a solid oak hardwood body.

tap-ki features 16 selectable musical scales from around the world. Inspired by hand-pan drums, these 16 musical scales each offer a different mood for your playing and exploration. The best thing about these selected musical scales is that it is impossible to hit a “wrong note”, No musical theory or piano playing ability is required to successfully enjoy this device. As seen in the demo video, the tap-ki can be played like a piano using single finger taps, or like a drum using both hands to trigger groups of multiple notes at once. The excellent velocity-tracking system allows the tap-ki to be played like a digital hand drum that responds to the smallest change in play pressure.

New Analogue Solutions FILTOPIA Analogue Monosynth Incoming

"Fusebox X is an analogue monosynth with 3 note poly capabilities"

Priced £1,799.00

Update: additional pics and details added.

Filtopia will be a limited edition synth - we are only building 200 units.

Stereo analogue monosynth - with a 5 Multi-Mode filter Filterbank - to give glorious and unique filter sweeps!

USP - THE FILTER BANK
Filtopia’s key USP is a bank of 5 analogue filters wired in parallel. Glorious multi-band filter sweeps are possible. With some tweaking you can also get vowel types sounds.

5 filters doesn’t mean just 5 filters, by having offset filter-cutoff frequencies, with some high resonance levels, can mimic the way the human voice works. Something that can’t be done with a single filter.

Aside from the uniqueness of a multi-channel filter bank for filtering, Filtopia is fully loaded with VCOs, LFOs, EGs, etc.

Filterbank - 5 analogue multi-mode filters - superb multi-filter sweeps, and even vowel sounds!

3 VCOs - can be routed to some or many of the filters as dictated by the front panel.

M‑VAVE FM‑1 Review & Sound Demo – Fun Pocket FM Synth

video upload by dongchannel

"How does this under‑$70 FM synthesizer perform? Check out this video for a full feature walkthrough, sound demos, and my honest thoughts.

I first spotted the M‑VAVE FM‑1 at this year's Guangzhou Musical Instrument Fair, and picked one up shortly after for about 300 RMB (around $60). The packaging is minimal, the unit itself is compact (16×9 cm), yet it packs everything you'd need. Connectivity is surprisingly generous, with both wired and wireless MIDI and audio support – really well‑equipped for its size.

Inside, you get a 6‑operator FM engine, essentially a recreation of a classic 1980s Japanese synth. It comes with 128 preset sounds, plus an effects chain, a 16‑step sequencer, an arpeggiator, and deeper editing tools. Pair it with an external MIDI keyboard and the playability expands even further.

Are there minor software quirks? Sure. But at this price, they're hardly worth mentioning. Compared to other portable sound gadgets in its class, the FM‑1 is just plain fun. And for the money, the build quality and feature set far exceeded my expectations."

"NOISFERATU is a compact handheld generative texture synthesizer. 45 algorithms across 5 banks produce crackling textures, noisy scapes, evolving drones, harmonic blips and digital chaos. Shaped but never fully controlled by four knobs.

They generate endlessly evolving textures, tones and rhythmic patterns. Designed to surprise, resist repetition and never quite settle. Dial in a crackling drone, a stuttering melody, or pure digital chaos.

The front and back panel can be flipped.

It uses and abuses creative approaches like generative wavetables, BitBend address manipulation, probability gates, bitwise logic operations and wild combinations of these.

Powered via USB-C.

Firmware and schematics are released open source."

Meet the upcoming "OAK-S37 Sampling Workstation" keyboard synthesizer.

Playlist with additional details:

1. OAK Sampler Sound Playback and Effects Test

I absolutely love the ASR-10. I’m building a new hardware workstation inspired by the ASR-10 that runs the original OS , effects etc and replicates the HW in a modern form. There will be some updates on the project. This is the boot and general test. Potato speaker recording. #asr10 #90ssampling

2. OAK Sampler (ASR-10 in Hardware) Sequencing & Sample Editing

I love the ASR-10. I’m building a new hardware sampler inspired by the ASR-10. It can run the original Ensoniq ASR-10 OS and effects algorithms. This video shows sequencing and sample editing on the OAK Sampler.

3. OAK Sampler (ASR-10 in Hardware) vs ASR-10 Sound Comparison

This video compares the OAK-S37 and an the ASR-10 using the same sequence, individual samples, filters, envelopes, and effects.

I recreated “93 ’til Infinity” as a test project using identical files across both systems.

I intend to do a limited first run eventually (no dates yet).

"Meet DVNA, a compact chord & texture synthesizer from Doboz."

Prologue to DVNAvideo upload by Doboz



DVNA walkthrough

video upload by Doboz

"DVNA is a compact synthesizer built for creating rich harmonic textures with minimal effort. Play a single key and get a chord, or intervals of your choice across its four oscillators... monophonic input, polyphonic results.

A built-in note quantizer locks your pitch to any of 25 scales, while the tuning modes let you dial in everything from fixed chord voicings to free microtonal tuning. Oscillator mixing and stereo panning are controlled through morphing systems, so a single knob sweep transforms your entire mix at once. The signal then flows through a stereo multi-mode filter, overdrive, and a choice of reverb or delays.

The 12-key capacitive keyboard responds to finger contact area, generating a continuous pressure signal that can be routed throughout the instrument. DVNA also accepts MIDI over TRS, syncs to MIDI clock, and responds to MIDI CC for external control. 128 presets capture all parameters, keeping your favorite patches ready to recall instantly."
