Just a Minute (JAM) - Live Ambient #19 (Relaxing Modular Sounds + Elektron Syntakt + OXI One + S-4)

video upload by ST Modular (Stefan)

"🟢 I found something cool on my mobile (...well, actually I only had this video in vertical format, so I needed some kind of workaround, which is that mobile frame 😉🎶).

✨ This is a live ambient modular synth performance! This set explores slowly evolving pads, hypnotic drones, and delicate rhythmic textures, performed live with Eurorack modulars, Elektron Syntakt, Torso S-4 and creative FX.

🎧Also perfect for deep listening, study, or meditation. Immerse yourself in evolving soundscapes and analog warmth.

💡 Gear used & roles in the setup:

♫ Elektron Syntakt → kick, percussion, live melody playing
♫ ST Modular Honeyeater + Disting MK4 (wavetable algo) → Pad 1 → through Mimeophone + FX Aid
♫ Behringer Victor OSC → Pad 2 → through Pico DSP + Intellijel Sealegs
♫ Bastl GrandPa → alternating samples → through EQ8, Pico DSP + Intellijel Sealegs
♫ OXI One → main live sequencing
♫ Torso S-4 → one-shots, drones, percussive tweaks

New Euphoria DIY Semi-Modular Desktop Synth by ST Modular

video upload by Stefan Tretau

Details via ST Modular

Coming soon..

A semi-modular analog desktop-synthesizer

Featuring a dual complex oscillator characterized by simple and clear operation and uncompromised sound

Designed as an instrument that can be built, exolored and learned

DO IT YOURSELF! EUPHORIA is only available as a DIY-project and was designed to be built by passionate builders. It consists of fourteen individual circuit boards that are mounted on one controller board

MAIN FEATURES

TWO ANALOG OSCILLATORS

Two Voltage Controlled Oscillators with classic waveforms, waveshapers, sub-octaves and a noise source. Convenient sliding potentiometers for volume control of the waveforms. Based on the famous CEM3340 chip and a newly developed wave-shaping tone generator.

TWO SEQUENCERS

Play notes with a 5-STEP trigger and CV sequencer and an additional 4-STEP CV sequencer. Transpose and change the length of a sequence, control the tempo via CV, add swing or sequence manually with the push of a button.

OSC MIX & VARI BOARDS

Seamlessly blend the oscillators manually or by CV. Insert external audio and pass it through the Filter or internal Reverb. VARI BOARDS are interchangeable boards, each offering a different functionality. Choose the VARI BOARD that meets your requirements.

DUAL LPG, VCA & ADSR

Each oscillator is processed by a filter-based low-pass gate (PLG) and both are optionally routed through an internal AC-coupled VCA. Use the internal ADSR envelope to shape and express your sounds.

MODULATION & TOOLS

Get your sounds moving with the internal CV-controllable LFO and the Buchla 281e-inspired function generator. Multiply, invert and amplify your signals with a buffered multiple and an additional DC-coupled VCA.

ST Modular - ALSTADEN (Waveshaping Oscillator)

video upload by Stefan Tretau

"ALSTADEN is your source for harsh and harmonically rich sounds. It is a newly developed waveshaping tone generator and resembles the secondary oscillator of the semi-modular synthesizer „EUPHORIA“. The waves are formed by a combination of diode clipping and folding of the waveform by adding mirror images of the upper and lower parts of the waveform. This creates more high harmonics and interesting timbral variations. It also features an equalizer, which is quite unusual for oscillators, but offers more sonic possibilities."

Published on Apr 6, 2019 Stefan Tretau

"18 minutes of random wiggling with the FLITZEM DEFÖR Sequencer being triggered from the Westlicht PERFORMER. The Oscialltors used are 2x Cyllene and 1x GIVE II.

Yes, there are some atonal and dissonant passages here, but thats part of the game when wiggling around. Any quantizer would solve that immediately (just didnt have one at hand)."

ST Modular - CV SCAN and UIT (Balanced Out) with Morphagene | CV SCAN, TRYFELO and EUROKASTLE

Stefan Tretau

ST Modular - CV SCAN, TRYFELO and EUROKASTLE


"Using CV SCAN to scan through different CV sources from Tryfelo to control EuroKastle Pitch. And using CV SCAN to route one CV source from Tryfelo to different CV inputs of EuroKastle. Scanning manually and via CV, using the Volt Output of CV Scan to change EuroKastle CV with the Scan knob and interrupting the CV SCAN route via gate signals and manually via the dedicated OFF button.
I´m also using the new Balanced Output Module "UIT" here.

This is not supposed to be musical ;-)"
