"I have been offering a synthesizer repair service since December 2025. While I had previously only occasionally breathed new life into the odd instrument, the closure of Radikal Technologies GmbH sparked a desire to find a way to continue pursuing my passion for synthesizers. When you have been personally involved in synthesizer development, the repair process constantly triggers moments of déjà vu alongside new insights. That exciting moment when an instrument is finished and invites you to play it again makes up for the days of work often poured into it.
This ARP 2600 had a variety of issues. The keyboard was in poor condition—with some broken contact springs—the voltage processor wasn't working, the oscillator scaling was terrible, all the faders were scratchy, and tuning the oscillators was an ordeal.
But time and love heal all wounds. Doesn't it sound great? The ARP 2600 is an absolute classic, and its sound possesses plenty of character, warmth, and precision.

"What happens when you build a vacuum tube-based hybrid synthesizer in a Soviet space lab and send it back from the future? Today we’re demoing, reviewing, and explaining MARS from Eternal Engine Electronic Musical Instruments — one of the strangest, most beautiful, and most aggressive modern synthesizers I’ve ever played.
MARS is often described as a four-voice polyphonic tube synthesizer, but architecturally it’s more accurately a paraphonic synthesizer. The four digital oscillator voices can be played across multiple notes, but they all share the same tube-based filter and vactrol-based amplifier. That puts MARS more in the tradition of instruments like the Korg Mono/Poly and Formanta Polivoks than a conventional analog polysynth.
In this video, I walk through the full architecture of the Eternal Engine MARS: the digital oscillator section, mono / duo / poly voice modes, pulse-width modulation, ensemble mode, FM synthesis, modulation matrix, envelopes, LFO, sample & hold, the gorgeous Nixie lamp interface, the resonant vacuum tube filter, and the asymmetric tube overdrive that gives this synth its raw, snarling character.
This is not a safe, polite, modern analog synth. MARS is boutique, unusual, heavy, beautifully built, and absolutely vicious when pushed. The tube filter and drive section give it a sound that feels alive in a way most modern synthesizers don’t — somewhere between vintage analog synth, industrial bass machine, experimental sound design box, and Soviet sci-fi artifact.
If you’re into industrial music, EBM, darkwave, synthwave, experimental electronic music, vintage synthesizers, boutique synths, tube distortion, paraphonic synthesis, analog filters, FM basses, PWM pads, or Polivoks-style aggression, MARS is worth hearing.
I also talk through who I think this synth is actually for — and who should probably pass on it. Because while I absolutely adore the sound, MARS is not a cheap “do everything” synth, and it’s not trying to compete with mass-market analog polysynths. It’s a character instrument. A monster. A special machine for people who want something truly different."
"Learn how to create a complete lo-fi track from scratch with the WoFi sampler. In this music production tutorial, film composer Josh Madoff demonstrates his creative workflow, from sampling and sound design to arranging a finished song using WoFi's powerful standalone features.
Watch as he transforms raw sounds into a moody lo-fi composition, processing breakbeats, layering drums, recording instruments, and shaping textures with WoFi's built-in effects and intuitive sampling engine.
Whether you're a beginner exploring sampling for the first time or an experienced producer looking for new sound design techniques, WoFi makes it easy to capture ideas, manipulate audio, and stay in a creative flow without a computer.
🎛️ In this video you'll learn:
• Breakbeat processing techniques
• Lo-fi drum layering and snare design
• Creative rimshot sound design
• Direct sampling workflows
• Field recording and instrument sampling
• Using the myWoFi companion app
• Bass recording and arrangement
• Vintage-inspired sound design
• Building a complete lo-fi track from scratch"
"Welcome to Volume 34 of my Torso S-4 Explorations.
For this improvised live performance, I set a strict creative limitation: use only one single sample (a drum loop) and one single track on the Torso Electronics S-4. The goal was to push the boundaries of the S-4's granular and sound-design engines to see just how far a single piece of source audio could be stretched, morphed, and reshaped into a variety of sonic landscapes.
The performance was recorded live with only minor edits for pacing. Final audio was lightly mixed and mastered in Pro Tools."
Lyra always has been a great sample source, and I really like the immediacy and playability of the OPXY.
Sculpting samples as I record, experimenting with slowing them down as I play create rich, stretched out textures. All harmonic content is being pulled apart and opens up a whole new world.
Sequencing modulation and effects on the OPXY add movement. Soma Warp was used to add some more movement at the end of chain.
