Figuring out the circuitry of old DIY drum synth

video upload by organfairy

"I play it manually at 3:23 and run it with a step sequencer at 4:17.

This is another un-documented one from the vaults - one that I, for some inexplicable reason, have not made any written information about.
So in this video I go through it and find out how it is made.

The music is 'No Hollywood movie', originally recorded by Lesley Hamilton, that was a hit in Germany in 1978. Same year it was recorded in Danish by Gitte Hænning as 'Hollywood drømme' and in German as 'Von Hollywwod Träumen'. I play it on my Yamaha HE-8 organ with Korg Rhythm 55 drum machine - but I probably didn't do a very good job since YT couldn't recognise it..."

Simple Synth-Pop Crossover Session | Nobi 2026-01-19 by atnr

video upload by atnr

"This piece was created using ‪@KORG_INC‬ microKORG S, ‪@teenageengineering‬ OP- field, and NTS-1, forming a simple synth-pop crossover track.

On the microKORG S, melodies are performed while switching between different patches. The output is processed with reverb via ‪@strymon‬ blueSky.

The rhythm is handled by the OP-1 field, while the bass is played by the ‪@KORG_INC‬ NTS-1. Both are triggered via MIDI sent from Ableton Live.

Although it does not appear in the video, the Nord Lead is used to play harmonic parts, with reverb applied through ‪@gfisys‬ Specular Tempus."

"Someone just saw Marty Supreme 😂. Trying to be like OPN with the 80s sounds. Quick jam with the Roland Juno 60 and the Dave Smith Tempest. Some reverb from the Strymon Bigsky Mx."

Doepfer Chaotic Patch A-112 Sampler / Wavetable Module!

video upload by Doepfer Musikelektronik GmbH

"Chaotic patch with the A-112 sampler!🪩🤸‍♀️

In this patch the A-112 is used as a lofi effect in the feedback loop of the A-119 Spring Reverb. All sounds are out of the system!
The bassline is a combination of the A-110-2 Basic VCO and the A-124 Wasp Filter. The A-188-1 BBD is used as a Karplus-Strong synthesizer.

Whimsical Raps Atrium // Monome Norns // 36 Minutes of Uninterrupted Ambient

video upload by Lesjamusic

"My friend Simon (aka mosaictapes on Instagram) came over the other day, and we were toying around with the Sines app on Norns. We added some noise options, including modulating the frequency with noise, giving this lovely instability to the sound. Then added two sequencers: One wave based and one stochastic drift based. Here the drift sequencer slowly plays the sine waves, represented by the bars in the Grid (sorry about the cable in the way!). DM me on IG if you would like a copy of this edited script.

I added an evolving bass drone on Atrium - something that's super easy to do with the internal gestures and LFOs. Cocoquantus has a little loop of the Norns, then there's Oto Bim and Boum, and Walrus Audio Slöer just off screen. There's no talking here, and no changes in the patch - I just thought I would leave it running for you to enjoy / mong out to 🫠🫠🫠

Exploring OXI ONE: Lazy Ambient Jam w. Moog Messenger, Vermona Perfourmer, Prophet 12 & Eventide

video upload by copenhagennoiselab

"'Sunday Excursion' is a relaxed ambient jam built entirely around two sequences from the OXI ONE.
No composition. No arrangement. Just hands-on exploration and letting the hardware talk.

🔁 SEQUENCING

The OXI ONE runs two independent sequences:

Sequence 1 – Rhythm / Pulse
– Matriceal mode for controlled randomness
– Drives a Moog Messenger mono synth
– Acts as the rhythmic backbone of the piece

Signal chain:
Moog Messenger → Klark Teknik KT76 → Korg DL8000R → TC Electronic Fireworx

Sequence 2 – Melody / Texture
– Linear mono mode with probability-based notes
– Drives a Vermona Perfourmer in round-robin poly mode
– Each voice slightly different for subtle movement and width

FX:
Vermona Perfourmer → Eventide Eclipse

🎹 LIVE PLAYING

On top of the sequences, chords and textures are played live on a Dave Smith Instruments Prophet 12.
The patch is a slow, restrained pad with a simple overtone structure.

FX:
Prophet 12 → Eventide H9 (Blackhole)

This is not a 'track.'
It’s a documented session exploring how the OXI ONE interacts with a few quirky synths and late-90s / early-2000s rack FX.

If you’re into hardware sequencing, probability, and letting small variations do the work, you’ll probably find something useful here."

Testing a new prototype Vco by making a psytrance track

video upload by Radical Frequencies Modular

"Testing the prototype of the upcoming Radical Frequencies Retro VCO, by making a new collaboration track with @martian_arts_official , where every sound (including the bassline), is made with the Retro VCO, recorded through various Radical Frequencies VCFs. Kick is Kick 3, drums are samples. This is the single VCO prototype but a dual VCO is planned as well with some added features. A new hard sync is added for phase re-triggered bass lines and solid tuning in FM modulation lead lines.
