Sequential 02 : Oberheim OB-6 Sound Demo : " Massive Mod " user bank preview by I.H.R


video upload by I Hate Robots

"Sequential Oberheim OB-6 (module) - sound demo of few user programs, this is not a jam, and the video is a loop, not in realtime.

00:00 Duality
04:20 X-Rhodes
08:15 Gate 1
10:05 Lux
12:15 Alien 1
14:06 Sun
15:10 Coma
17:02 Gate 2
18:22 Nop
19:31 Dark Phaz
22:40 Omniarp
25:00 Alien 2
26:25 Berlin Mod
29:35 Crispy Pad

In practical terms, the OB-6 (keyboard or module version) is a modern and refined embodiment of all the experience and expertise of Dave Smith (Sequential) and Tom Oberheim. Its sound engine sits somewhere between the Sequential Prophet-6 and the Oberheim OB-Xa; it's essentially a fusion of the two!

It's high-end, old-school analog in the purest tradition—the sound is big, fat, deep, and powerful—but with modern digital assistance that allows it to fully exploit its capabilities and push its boundaries.

This is precisely the subject and purpose of this preset bank, which I designed entirely myself.

This is my main OB-6 bank, which I use very often for my sound design work in the studio or for my training sessions. User Bank #3 (Massive Mod), it contains a total of 96 custom presets. I'm not presenting them all here, the demo would have been far too long, but I've prepared this short demo with a few of them to give you a sonic preview of the synth and its modulation capabilities!
Sometimes I use a single preset with its modulations, either played directly on the keyboard or sequenced with a keyboard layer on top, and other times I mix two presets together (the OB-6 is monotimbral).

Everything you hear comes from the OB-6; there are no added effects, no post-production processing !

"Todd Barton with Buchla Music Easel and Eurorack

Making this public, my OSU Soundbox 4 virtual performance from 2021. Eager to perform live for Soundbox 9 in May 29-30.

The original post:

Dear Patrons, I'm so glad to share this little improvisation with you. It premiered last night at SoundBox4 https://liberalarts.oregonstate.edu/s... That festival is still going on today and tomorrow and it is free, you might like to check it out.
I surely miss performing live but when I turn on the video and audio recorders and imagine an audience it is an exciting alternative. I hope you enjoy this. All best wishes, Todd"

KOSMOS – A Generative MIDI Sequencer for RP2040 (DIY Project)



You might recall KOSMOS from previous posts here. Plantssystem aka GreyScale wrote in to let us know the source code has been released. Details and link to the github repository follow.

"KOSMOS is a compact, self‑contained generative MIDI sequencer built on the Raspberry Pi Pico (RP2040).

Power it on, and it immediately begins producing evolving melodic patterns — no DAW, no clock source, no setup.

The project combines a Euclidean rhythm engine, Japanese‑mode melodic generation (Hirajoshi / Insen / Miyakobushi),
and a 240×240 LCD UI for real‑time visualization of steps, probabilities, and phrase movement.

A small instrument with a surprisingly expressive voice.

The Joy Of Repeating Riffs Over Changing Chords


video upload by EZBOT

"When I first started writing songs it was all about a cool guitar riff over a strait bassline or a solid chord progression. It's the best feeling, it's so simple and satisfying. Let's lean into it and talk about it while using the M8 Tracker."

video upload by LFOstore

"The RMIF Opus (РМИФ Oпус) is a rare analogue string machine/synthesizer made in Riga, Latvia by the Riga Musical Instrument Factory (RMIF) in the year 1988.

The sound range is five octaves and the instrument consists of 4 sections — piano, that synthesizes piano like lead soundings of different timbres, analog string machine, that plays wonderful string sounds with soft attack and with the possibility to control release, tremolo and the pereodically repeated beat-fading sounds.

A flexible bass section, that is controlled by 2 lower octaves, that contain three 8' and two 16' registers.

The Opus is based on divide-down technology with a master oscillator and has very nice multimode filter (LPF, BPF and HPF with resonance), a fantastic chorus, ring modulator, vibrato and a lot other features."
