KINTSUGI - a song by Gattobus

video upload by gattobus

"Kintsugi is a Japanese art that consists of repairing broken pots or cups with a gold filling. I think we should do the same with our lives. Whenever you feel broken or incomplete, try to fill yourself with what you like the most. We all have to find our own 'gold', the things that can fill the gaps in our soul.
Music is my gold. This is what this song is about.
I hope you like it.

If you do, please consider subscribing to my channel and sharing my work. Thank you!

This is a real-time performance played with my Buchla Easel Command 208C.
Drums and synth parts added later.
Mixing and mastering in Ableton Live 12."

Half-Time Techno w/ TR-808, TB-03, and OP-1 field | Lopho 2026-08-08 by atnr

video upload by atnr

"A half-time techno piece created with the TR-808 (MIDI modified), TB-03, and OP-1 field.

On the TR-808, the bass drum and snare are routed through separate outputs. The bass drum passes through the SANSAMP BASS DRIVER DI. The snare is processed through the NIGHTSKY with heavy reverb and filtering.

The master output is connected to the blueSky, allowing reverb to be applied to the overall drum mix.

On the OP-1 field, percussion sounds are glitched using a modulated delay created with the CWO effect.

On the TB-03, a bassline is looped while the filter is adjusted in real time.

The OP-1 field is used as the master clock. The TR-808 and TB-03 are synchronized via MIDI clock."

Poly Rave 👾 (Waldorf PROTEIN // Roland TR-6S // JU-06A // Moog DFAM // Squarp HAPAX)

video upload by 2-Minute Warning

"This time, I'm introducing a new instrument to the setup: the Waldorf Protein, used here for the CHORDS 🎹

The rest of the setup is made of a Roland JU-06A for the BASS, a Roland TR-6S for the DRUMS (no samples used, only ACB analog behavior engine with mainly the TR-808 model) and, for some additional percussion, the only analog instrument in the setup: the good Moog DFAM 🤩

Everything is sequenced by the Squarp Hapax, with quite a few things happening behind the scenes as usual.
MIDI LFOs are used to modulate some parameters of the TR-6S, while automation takes care of changing parameters on the JU-06A during the performance.

This time I also decided to use the Hapax's physical MIDI ports rather than relying on USB MIDI:
MIDI A : Roland TR-6S
MIDI B : Roland JU-06A
MIDI D (TRS) : Waldorf PROTEIN

And then there's the DFAM... which, as usual, refuses to speak MIDI. 😄
Since the DFAM doesn't have a MIDI input, I sent very short Gate pulses from the Hapax (Track 11) to simulate an audio clock, allowing its internal sequencer to advance in sync with the rest of the setup.

So, quite a lot going on behind what hopefully sounds like a relatively simple piece of music!

Another little experiment in making several machines behave together without making the whole thing look like a NASA control room 😄

As always, the performance itself was recorded in a single take. I do the mixing and mastering afterwards in Ableton Live."

Roland Juno-106 | Custom Sound Bank Demo | 80s Vintage Analog Synth Classics

video upload by RetroSound

"Experience the legendary Roland Juno-106 with a collection of custom-made patches created by RetroSound.

This no talking demo showcases original sounds ranging from warm analog pads and lush strings to punchy basses, expressive leads, classic brass, and atmospheric textures. Every preset was programmed from scratch to highlight the unmistakable character of the Juno-106.

Featuring 6 voices of true analog polyphony, digitally controlled oscillators (DCOs), a rich 24 dB/oct low-pass filter, onboard stereo chorus, and full MIDI implementation, the Juno-106 remains a favorite among musicians and producers around the world.

Roland Juno-106:
• Released in 1984
• 6-voice analog polyphonic synthesizer
• 61 full-size keys
• Digitally Controlled Oscillators (DCOs) for excellent tuning stability
• Classic Roland 24 dB resonant low-pass filter
• Stereo Chorus I & II for the signature Juno sound

J3PO // History

video upload by Julian "J3PO" Pollack

"Julian 'J3PO' Pollack performs an original composition, "History," a live DAW-less performance recorded entirely in one take with no overdubs.

Built around a sequencer, hardware synthesizers, and an acoustic (felt) piano, "History" explores the space between composition and improvisation. Every musical decision unfolds in real time, allowing the performance to evolve naturally from a simple repeating pattern into something entirely its own.

Gear used:
• Arturia KeyStep Pro (sequencing)
• Roland TR-8S
• Oberheim Two Voice Pro
• Groove Synthesis 3rd Wave 8M
• Yamaha Acoustic Upright Piano

Effects:
• Meris Mercury 7
• Strymon Timeline
• Strymon El Capistan

Symphony No. 7 - Mvmt 2 Vibe

"Another jam with the JX-3P and the Juno-6.
This one feels a bit like Beethoven's Symphony No. 7, second movement."

"A quick jam with the JX-3P and the Juno-6.
It's very interesting that I find the sequencer on JX-3P to be the most usable sequencer I've ever came across."

Korg NTS-4 Performance Mixer | SonicLAB Review

video upload by sonicstate

"We look at the ‪@KorgOfficial‬ Korg NTS-4, a compact Nu:Tekt performance mixer kit with audio interface. Assembly is simple, with clear instructions and no soldering.
It has two mono inputs, four stereo inputs, stereo send and return, cue monitoring, USB retrurn level, headphone output and a two-channel USB audio interface running at 24-bit/48kHz.

There are two FX engines, one on the send which includes delays, reverbs, chorus and a range of master effects such as filters, phaser, decimator, drive, distortion, compression and limiting.
These effects are fixed rather than expandable via the Logue SDK of others in the Nu:Tekt range , but they suit hands-on performance - albeit a little fiddly.

The cue system works pre-fader, giving a basic extra bus at a pinch.
USB ground loop noise is possible in some setups.

Price is around £200"

Iván's Fotonovela: The Madrid Hit That Conquered Europe | Full Reimagination

video upload by Nostalgic Explorer

"Iván – Fotonovela Full Stems RAW and With FX are available on my Patreon: / nostalgicexplorer

This time I'm heading to Madrid. Fotonovela came out in 1984 and did something strange — it barely cracked the Top 20 at home in Spain, then went Top 5 across Europe. A Spanish record the rest of the continent adopted first.

Everybody files it under Italo disco. There's a good reason for that, and it's not the one most people assume — I get into it in the video.

There's also a bigger story here about what was happening in Spain in the 80s, and why a singer from Madrid ended up making one of the best synth-pop records of the era. That one you'll have to watch for.

For this reimagination I'm using the Moog Voyager for the bassline, the Roland Juno-60 for the accordion, organ and bell parts, the Oberheim DMX for drums, and a Mellotron VST for the strings — all arranged and mixed in Logic Pro.
