Groovebox MIDI Reactive VJ - HTML Video Synth Test

video upload by space fever

via Space Fever:

"I would like to submit a small independent synth-related visual tool I made.

It is a MIDI-reactive VJ / HTML video synth designed for grooveboxes and hardware setups. It runs in a browser and reacts to incoming MIDI CC / clock data, making it useful for live electronic music, acid techno, groovebox jams, and hardware-only performances.

Product page: https://spacefever.booth.pm/items/8528673

The concept is to keep the setup simple: a groovebox or MIDI controller sends MIDI data, and the browser-based visual synth generates reactive glitch/noise-style visuals without needing a full VJ software environment.

It may be of interest to readers who use grooveboxes, MIDI hardware, DIY performance tools, or browser-based visual instruments."

M5Stack Acid Generator in there as well.

Wheel Within the Wheel EP by Michael William Gilbert

A new release via supporting member Michael William Gilbert via Tall Dog Electronics (tindie)

Hello friends,

I am very happy to share this new project with you: an EP of original electronic/electroacoustic fusion music. There are six tracks, including the single "The Prayer Is The Road"(a)/"The Road Is The Prayer"(b). To be clear - prayer in my context is secular: "a practice focusing on gratitude, mindfulness, and reflection to foster positive change, connection, or resilience without appealing to a supernatural being".

"Wheel Within the Wheel", the title track, is influenced by a visit to Tibetan Buddhist monks while they werein the process of creating a sand painting and then destroying it. "Fractal Loup" is about a state of active and curious meditation, a metaphorical wolf mind interpreted with looping. "The Float" is a dream through the worlds of techno and Berlin school. All music recorded & mixed at Alibi’s Little Corner Studio by MWGilbert and mastered by Sean Magee.

Upcoming: thanks to my partners at ElasticStage, "Wheel Within the Wheel" will soon be available as both an LP and a CD! You can check out my previous album "Electronic Music": https://elasticstage.com/mwgilbert

Hope you enjoy "Wheel Within the Wheel". I'm always pleased and grateful to hear what you think, so please let me know!


Thanks for listening!

GS-e7 analog poly synth + BlueARP, EDM demo, no talking

video upload by graywolf2004ru

"A few months ago I got GS-e7 synth (7-voice analog poly) and finally managed to give it some good demo with BlueARP.
Playing various BlueARP-driven patterns, starting from barebone mono pattern to rich polyphonic pattern.
All sounds recorded directly from GS-e7, no other FX except its onboard delay (chorus was not used)."

DS8 v0.3 Update! New: Sampler Slicing, Resampling, Step FX, Presets and more.

video upload by Intermynd Instruments

"DS-8 v0.3 Release Notes

Sampler (SP track) — Record from mic/line input or resample the engine output back into a sampler track. Waveform editor with trim/crop, slice editor with transient detection and grid mode, per-slice ADSR and reverse, tone controls (bass/mid/treble boost and low-pass/high-pass filter), one-shot mode.

4 new percussion engines — Tom 808, Tom 909, Zap, FM Hi-Hat.

Step FX — Per-step play conditions (every 1st/2nd/3rd/4th pass), ratchets with flat/fade/rise velocity shapes, and microtiming nudge (±6 ticks).

Preset browser — Save/load/preview/rename/delete presets (.ds8s format). Preview voice lets you audition without changing the track.

Resample recording — Bounce sequenced patterns into audio. Beat-sync arm on the downbeat, feedback prevention by excluding the armed track from the capture.

Rec monitor — Hear the mic through the main output while recording.

Track mute fades — Smooth fade-out when muting instead of abrupt cuts.

New and improved keyboard interface for saving Projects and Presets.

=====

DS8 Drumstream is still in active development. This is v0.2, so expect bugs, rough edges, and frequent changes.

EEH / SSB Banana 6-voice Analog Polyphonic Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

Ad scan below.

"In near mint condition, with factory MIDI. Voice boards and PSU recapped, calibrated. The autotune function has been deactivated because we have calibrated the filters to be able to self-oscillate and apparently that is incompatible with the autotune check on startup, but the synth is fully tuned. Copy of user manual (in german), schematics and docs included. 220V version.


The Banana is a 6-voice polyphonic synthesizer that, in terms of design, strongly resembles the famous Oberheim OB-Xa, but it is not an OB-Xa clone. It features an OB-Xa-like voice architecture with two CEM3340 VCOs, a switchable 24dB lowpass/highpass filter based on the SSM2044 chip, and CEM3360 VCAs and CEM3310 Envelope Generators for the six voices. This provides a rich, warm analog sound that is still relevant in modern music productions. The Banana allows for sound editing with the versatile 2 ENVs (envelopes), similar to those found in the OB-Xa, making it a powerful instrument for both complex soundscapes and powerful leads and basslines.

The Banana was produced in West Germany by Electronic Engineering Hoffmann (EEH), in collaboration with Synthesizer Studio Bonn (SSB), and it is the only synthesizer ever released by EEH and distributed by SSB. In 1983, Electronic Engineering Hoffmann (EEH) completed the development of the Banana in collaboration with Synthesizer Studio Bonn (SSB), the world’s first specialized synthesizer store, located in West Germany. SSB had already made a name for itself by creating custom sequencers, including the Synthorama, which was used by Kraftwerk to control their Minimoogs on the legendary Trans-Europe Express.

Production of the Banana ran from 1983 to approximately 1985, after which the synth was discontinued. Only 100 to 300 units were made. This makes it a particularly rare model for collectors or musicians looking for a unique synth.

This model offers a unique opportunity for the serious synthesizer enthusiast or collector who is searching for a rare instrument with historical value.

Don’t miss out on the chance to own a piece of synthesizer history!"

EMS Synthi AKS - Beautiful example just serviced by EMS

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"This is an excellent original example of the highly sought-after EMS Synthi AKS. Our client has owned the instrument for over 40 years and used it primarily for home recording until approximately 1995, after which it was stored.

Following inspection, the Synthi AKS was sent to EMS for a full service, with repairs carried out where required. This recent factory-authorised servicing by EMS significantly reduces the uncertainty often associated with vintage Synthi ownership.

Serial number: 45138KS

Cosmetic Appraisal:

The instrument remains in excellent original, unmodified condition. The control surface shows only light age-related wear consistent with a Synthi AKS of this vintage. The Spartanite case presents well, with some marks from use, and the nickel catches and hinges show an expected aged patina while operating correctly. No keys are supplied for the case locks.

This EMS Synthi AKS arrived with a heavily worn set of original matrix pins. To address this, a complete new set has been purchased directly from EMS and is included in the sale.

The service by EMS covered all the critical items, including replacement of ageing power-regulation capacitors, deep cleaning, and calibration. In addition, the following work was carried out by EMS at our request:

1. VCO stabilisation modification implemented

2. All three VCO potentiometers replaced

3. Joystick potentiometer replaced

4. Full set of twenty-one new matrix pins supplied



Details of the repairs carried out by EMS are itemised in the service invoice, a copy of which will be supplied to the new owner. As the manufacturer has carried out the servicing and repairs, we are satisfied that the instrument is operating correctly and it is therefore sold with our 90-day warranty.

This Synthi AKS operates on either 240V or 110V mains supplies via the built-in voltage selector."

The Summer Constellations for Gong, VCS3 and ARP 2600

video upload by R. Reger

"The core of this piece is how the gong interacts with feedback from the VCS3 that I generate by overdriving the synth’s reverb module. If you’re a synth fan, the synth action in the first part of the piece is minimal but gets more involved in the second half."
