"A vintage Elka OMB 5, the programmable arranger / rhythm unit specifically designed for Italo Disco, in perfect working condition and in mint cosmetic shape. The deal includes its ultra-cool original bag, owner’s manual, and a Song RAM cartridge. UPS fast delivery and professional packing guaranteed.

Released in the mid-'80s by the Italian manufacturer Elka, the OMB-5 (One Man Band) is a powerful yet easy-to-program arranger featuring a rhythm unit, a bass channel, and two accompaniment tracks.

RHYTHM UNIT

The OMB-5 comes with 20 preset rhythms (Disco, Funk..), each with four variations, one of which is fully programmable by the user — for a total of 20 storable custom drum sequences. Each preset rhythm also includes two fill-ins, an intro/ending, and a dedicated break.

The 32 drum sounds are the same as those found in the iconic Elka Drumstar 80: a cool selection 8-bit PCM drum samples, a perfect mirror of that unmistakable '80s aesthetic. The rhythm section is extremely easy and intuitive to program, and the ability to edit individual drum sounds within a recorded sequence using a single 'cancel' button is simply brilliant. A true example of vintage Italian clever design.

SOUND SECTION

The Elka OMB-5 features a powerful and flexible sound section totally based on FM synthesis and divided into three blocks:

Bass (6 voices)
Presets 1 (12 voices, 5-note polyphony)
Presets 2 (12 voices, 5-note polyphony)
Each block supports 6 arrangements per preset rhythm, with Arrangement 6 fully programmable, allowing up to 20 custom sequences to be stored per block (Bass, Presets 1, Presets 2).

Bass sounds : STRING BASS, BASS FLUTE, BASS GUITAR, ELECTRIC BASS, FUNK BASS, TUBA

Presets 1 sounds : STRINGS, BRASS, ELECTRIC GUITAR, BANJO, JAZZ GUITAR, MARIMBA, VIBRAPHONE, CLAVINET, ORGAN 1, PIANO 1, SYNTH 1, SYNTH 2

tc electronic 2290 p Delay with Synths - No talking Demo


video upload by Limbic Bits

"tc electronic 2290 p Delay with Synths - Twisted Electrons MEGAfm and TWISTfm

This video shows the TC Electronic 2290 P Dynamic Delay, a modern pedal interpretation of the classic 2290 rack unit (which I’ve never owned but always found interesting). Build quality is solid and confidence-inspiring, and feature-wise it’s a moderately flexible digital delay with filter, true stereo, delay subdivisions and multiple modulation sources that allow for controlled, musical movement."

Squarp Instruments Hapax as the controller.

12/28/25 ARP 1623 + ElectroComp EML 200 + Peavey DDL-3 + CXM 1978


video upload by Cfpp0

"I think this is the first time I sequenced the EML 200 with the ARP 1623. The sequencer is 1 volt per octave and the synthesizer is 1.2 volts per octave, but it still works. Here the gate bus 1 on the ARP is triggering the envelope on the EML, which controls the VCA both VCOs are running through. That signal then runs through the EML spring reverb into the Peavey DDL-3 delay to the Mackie Onyx 1640 mixer, where the dry is panned left and the wet is panned center. Both have stereo reverb blended on the CXM 1978."

Layered Synth Resonance in Cinematic Ambient Space | Geological Survey 2025-12-29 by atnr


video upload by atnr

"This piece was created using the ‪@YamahaSynthsOfficial‬ CS01.
It is a cinematic ambient composition built from layered, hand-played synthesizer tones that resonate and expand over time.

The CS01 is connected to the ‪@ChaseBlissAudio‬ MOOD MKII and blueSky.
On the MOOD MKII, delay is applied and micro-loop textures are generated, while the ‪@strymon‬ blueSky adds spacious reverb.

The performance is shaped in real time by manually adjusting the filter on the CS01 as it is played."
