The Dual Stereo Looper, released in July 2026, is a collaborative effort between P4L and Ambivalent Instruments.
It is a 2-channel stereo looper in Eurorack format.
In addition to basic recording and playback functions, it is equipped with features such as pitch shifting, reverse playback, filtering, and reverb. CV control allows for sound design characteristic of modular synthesizers.
In this video, we will take a deep dive into everything from the module's basic functions to practical applications using CV.

If you like these sounds, you can buy the complete 03R/W SysEx bank from me with all 80 presets for 10 Euros (contact me at: vukansto at gmail dot com).
So, this is an old KORG ROMpler from 1991, a cut-down version of the flagship 01R/W. The 03R/W has less sample ROM (5 MB vs. 6 MB on the 01R/W) and lacks the Waveshaping and Emphasis features. Korg named this digital synthesis engine AI2, which stands for Advanced Integrated Synthesis (second generation). The first AI generation was featured in the M1 and T series.
Actually, I planned to sell this 03R/W, but now I'm not so sure. It reminds me of some mystic, dark sounds I created on the T2ex that I sold a decade ago. Now, I have those similar sounds in a compact 1U rack unit.
Recorded directly form 03r/W audio output to Tascam DR05x recorder (24bit / 48 khz)
Korg 03R/W specifications:
32 polyphonic (16 poly in dual Osc mode presets)
8 parts multitimbral (16 parts in General MIDI mode)
255 multi samples (5mb ROM of 16bit samples)
Single or dual oscilator structure per program/preset
Digital low-pass filter (VDF) per oscillator
2x digital effects processor (reverb, delay, chorus, distortion, etc.)
229 programs-presets (100 RAM + 129 ROM GM) and 100 multi combinations
PCM and RAM data cards expansions
4 analog audio outputs"
If you came for metallic falcon screams, jump to 1:19. This unbranded 2050 module was made custom by Jakub Jasiński for the previous owner. It’s plugged in a 4ms pod, but it’s getting 5v DC externally. It’s not a clone, but it seems to have been based on the Zerosum Inertia 6550-99, which is probably the greatest voltage controlled oscillator of all time. The Ladik S-143 (through the U-202 and multiplied) is sequencing the 2050 tune input and pulse input, as well as the MFB OSC-2 CV1. The triangle on the OSC-2 is running to the sync input on the 2050. An envelope from the MFB dual ADSR is running to the 2050 drive input. The delay is from the Peavey DDL-3 and the reverb was blended on CXM 1978."
"Meet the keypad version of Samplotron — my DIY hardware sampler and loop player built around the ESP32.
In this demo I’m using Samplotron to trigger samples and loops live. Some of the sounds are my own recordings, while others come from publicly available sample sources.
What you hear is the direct audio output from Samplotron — no post-processing, EQ, compression or additional effects were added to the recorded audio track.
You can also see another one of my DIY projects in action: a small oscilloscope I built, displaying the audio waveform in real time.
"Welcome back to @abregegere! In this extended, explorative sound design session, I’m pairing the chaotic brilliance of the Speak & Glitch by Error Instruments with the deep processing power of the S-4 by Torso Electronics.
We start by establishing a gritty base sound on the Speak & Glitch, dialing in some fundamental compression and reverb on the S-4 to glue it together. From there, we dive into the deep end—leaning heavily into the S-4’s robust modulation capabilities to transform the audio into evolving, quasi-generative soundscapes.
This session is only lightly annotated to let the sound design speak for itself. Feel free to use the timestamps below to jump straight to the sweet spots!

"🌅 A new Drum & Bass live session performed at sunset by the Black Sea in Odesa, Ukraine.
Built live with Elektron Digitakt II, Digitone and Roland S-1 🎛️ — melodic DnB, deep bass, psychedelic synth textures and evolving hardware sequences.
This time I also brought Virus synth sounds into the track, adding a deeper psychedelic character to the mix. 🌀
Roland S-1 takes a special role in the transitions, creating wild evolving effects and sequences, while Digitakt II and Digitone drive the groove, bass and melodic layers.
🌊 One of the most beautiful sunsets we’ve captured for an Imagination.Project session — electronic music, psychedelic sound and the Black Sea coming together in one live performance.
Recorded on the Black Sea coast in Odesa, Ukraine. 🇺🇦"
"Liquid Drum & Bass performed live by the Black Sea in Odesa, Ukraine. 🌅
A melodic sunset DnB session built around Elektron Digitakt II, with live-recorded guitar and trumpet adding an organic atmosphere to the electronic groove.
Everything comes together with melodic samples, deep bass, live sequencing and evolving effects as the sun goes down over the sea."
Liquid Drum & Bass LIVE 🌅 Sunset Digitakt II Session
"Sunset Drum & Bass performed live by the Black Sea in Odesa, Ukraine. 🌅
This time the session moves into a warmer African-inspired DnB vibe — melodic rhythms, percussion and electronic textures performed live on Digitakt II as the sun goes down over the sea.
No studio. No prepared stage. Just hardware, music, rocks and the Black Sea.
🎛️ Performed live by Andrii Averin
• Elektron Digitakt II
• live sequencing & performance

"In this extended, unannotated sound demo, I’m using the Cyma Forma Rnd as a standalone generative synthesizer, processing its audio live through the Torso Electronics S-4.
🎛️ Routing & Setup:
• Track 1 (S-4): Acts as the main track for the Rnd.
• Track 2 (S-4): Heavily processed, functioning as an auxiliary send track for the Rnd to create vast textures.
• Tracks 3 & 4 (S-4): Occasionally bringing in a drum loop to anchor the generative chaos.
Note: The audio in this video was recorded live and then lightly mixed and mastered in Pro Tools."
Sound demo of the VITA SYNTHS Modular Algorithmic Bass Drum Eurorack Synthesizer ADS-BD with no effects, accompanied by the VITA SYNTHS Modular Algorithmic Closed & Open Hi-Hat Eurorack Synthesizer ADS-HH and Behringer PRO-800.
A demonstration of the DR-SEQ-64 module by VITA SYNTHS, showing how to:
delete an existing pattern,
create a new pattern,
save and later load a pattern.
The video also shows that an unsaved pattern is not lost if the module is powered off unexpectedly, and it will be restored when the module is turned on again. This feature helps prevent loss of unsaved patterns.
"Today I wanted to take a bit of time to explain my deep love for the Dirtywave M8 Tracker while going over the patch notes for the new OS that was released last week. The new OS brings a slew of upgrades to the device in both sound and presentation. Let's check it out and make some tunes."
"A quick demo of some of the new features in Elastic Melody Update 1.2."
"Here comes the full list:
MASTER SECTION
• Added a master level control • Added a simple volume meter
OSCILLATOR
• Added four more oscillator waveforms for a wider range of sounds • Added new modulation options: – Pitch Modulation – FM Modulation (IAP) – Decaying FM Modulation (IAP)
"I tried combining the cyma forma RND synth with the Torso S-4!
All the synth sounds come from the RND, and the drums are played through the S-4.
By feeding the RND’s sound into the S-4 and applying granular effects in real time, the phrases sound even more dazzling!
It’s also convenient that I can power the RND directly from the S-4 via USB and sync MIDI between them!"
"Welcome to Vol. 41 of my Torso S-4 explorations! In this video, I take on a blind 4-sample challenge: building a complete 4-track ambient soundscape from scratch using four randomly picked samples from the Bastl MicroGranny library. Because the files use non-descriptive, sequential labels, I had no idea what sounds I was getting until they hit the tracks.
With zero planning and no preparation, every decision is made on the spot. I work through each track sequentially, sculpting textures, grains, and filters to weave unrelated sounds into a cohesive sonic environment. Toward the end, I break down how to set up and perform with Macro modulations to bring dynamic motion across the entire patch.
The video is heavily annotated with on-screen notes detailing each step of the sound design workflow, modulation routing, and granular processing.
• Instrument: Torso S-4 Granular Synthesizer
• Source Material: Bastl Instruments MicroGranny Factory Samples
• Post-Processing: Lightly mixed and mastered in Pro Tools"
"The Techno Performance Mixer V2 template for the Elektron Octatrack transforms your Octatrack into a versatile DJ mixer. Included are 64 scenes grouped for a fun and convenient workflow. Dual bus recorders offer a versatile way to perform builds, drops, and transitions. In today's video I teach how to use it, what inspired, and who it's for.
