"3 Voices 3 Rows" on Cwejman S1 / GRP R24

video upload by kapillarkraft

"Since I don't appreciate big setups so much, I tried to accomplish a Berlin School - style piece on an analogue monophonic synthesiser with external sequencing. Now that the Cwejman S1 is not your regular mono synth, I got 3 independent voices out of it all by itself.

Have fun watching."

The Grp Synthesizer R24 is a powerful CV and gate sequencer in the tradition of classic Moog sequencers, with extended options for fine voltage tuning and complex rhythmic generation. With three total tracks of CV and Gate control and extensive opportunities to reorder steps, run sequences at different speeds, and complex gate ratcheting, and more, the R24 is an ideal controller for any CV/Gate or MIDI-capable instruments, providing a central workstation for create intricate control and timing relationships. With complex step order permutations, integrated clock dividers per row, support for MIDI clock,and easy access to 1/4" CV/Gate I/O, the R24 easily integrates into and adds tremendous depth to any type of electronic music setup, modular, semimodular, digital, or otherwise.

Nice view.

GRP R24 Sequencer - Performance Rig #shorts

video upload by O.Z. Hall

"This is a demo of the R24 sequencer. I wanted a portable sequencing solution that was fun to play. I mounted the GRP R24 sequencer in a Synthesizers.com QCP22 Portable Cabinet. I have a number of modules, including the new Synthesizers.com Q169 and Q168 Oscillator++ Combo, providing oscillator/env/amp as well as raw noise. I've also got two Z506 Swiss Daisy DSP modules, a well as bandpass filter, VCA, mixers, etc.

There are 4 voices total. Here are the voices in order of 'introduction':
1) Z506 Swiss Daisy DSP in voice/delay mode. CV/Gate from R24 Row 1.
2) The Q169 oscillator 1 processed through the Swiss Daisy DSP for VCF/VCA/ADSR. CV/Gate from R24 Row 2.
3) The Q169 oscillator 2 set to a noise waveform and processed through the Q169 VCA 2/AD envelope. Gate from R24 Row 2.
4) The noise from the Q168 is processed through a VCA/ADSR. The timbre is modulated by a multimode filter (mostly bandpass). Filter CV/Gate from R24 Row 3.

I hope you enjoy watching this as much as I enjoyed making the video!"

GRP A2 + OTO Bim & Bam // My new favorite MONO SYNTH

video upload by Dexba

"So I stumbled upon a GRP A2 the other day, and I already love it.

There is something cute in its 5U enclosure, like a baby modular, as the OTO are definitely cute with their boxy, a bit cryptic, design.

I wanted to record a jam that could highlight some of the most prominent features of both the synth and the pedals. We have an arpeggio, very classical, almost Bach-sounding, going into a classical delay and a short reverb, then we get to a lush, water-like, filter playing, supported by a long and frozen reverb and a way more strong, hazy delay. In the end, the jam gets modern, with no delay, a very short reverb, just to give more air, more space to a powerful jumping sequence with some gnarly filter action.

Both the GRP A2 and the OTO are a pleasure for the dawless jammer, with all you need in plain sight. The only thing missing is a proper sequencer (GRP sells one too, the R24, but it costs almost twice the A2 synth, so...), but I have my handy Synthstrom Deluge always ready for that! Enjoy ✨"

ARP 2600 w GRP R24 Sequencer + Swiss Daisy DSP

video upload by O.Z. Hall

"The GRP Synthesizer company's R24 sequencer is driving two voices on the ARP 2600 and a third voice provided by the ZebraSynth.net Swiss Daisy DSP module, in "pluck voice" mode, with delay and reverb.
I'm using several features of the R24 including:
3 separate sequences (CV/Gate out ; MIDI also available)
Some sequences use the "ratchet" feature to double gate a single step.
The second row is only 6 steps, to provide a poly-rhythm for greater complexity (less monotonous ).

Thanks to my long time friend Rod Scott for loaning me the GRP R24. Check out his channel:

"the grp r24 is a 8x3 analog step sequencer firmly based on the mighty step sequencer previously developed in grp a8 and a4 analog synthesizers. the new r24 is full of control capability with cv/gate, midi and usb connections. hardware-wise, is stand-alone self powered, with hardware compatibility for mount on 5u module format; you can use in stand alone with its internal power, or you can install in your dot.com/cotk/moon modular system. r24 respects electrical and mechanical standards for the above manifacturers.

with the appropriate brackets included in the package the machine can be easily installed in a 19 "rack still, you can use r24's own cabinet as a "presto-cabinet" for powering and using your spare 5u modules. r24 has 64 internal memories for store and retrieve separate sequences; each sequence can be set in 8x2, 16+8 or 24 mode, with any step lenght user's selectable. r24 can act as cv/gate sequencer or as midi sequencer, with separate rows for midi note selection and for key velocity step adjust."

Enjoy my live Recording with lots of improvisation inspired by Floyd, Krautrock and classic Berlin School.

Used Synths &FX:
Behringer Model D + Pigtronix Echolution 2 Deluxe (Lead),
Korg ARP Odyssey + EHX DMM TT1100 + Neunaber Wet Stereo (Lead & FX),

KRAUTROCK PHASER with Roland Juno 60

Published on Feb 12, 2018 Rob Welt

"My very warm, rough and vintage sounding Krautrock Phaser, a clone of the famous Schulte Compact Phasing A.
The sound is the opposite of an analytic phaser. It has its own live.
Demo is made with Roland Juno 60 and a little bit of OTO BAM Reverb. the first seconds is the Juno clean without phaser.
After 5 Minutes I used CV of my GRP R24 to control the Krautrockphaser . First through the Footswitch Input then through the real CV-Input. AT the End I used the internal LFO of the Phaser.

No other external FX, no Mastering"
