This one is in via Florian Anwander via the Sequencer.de forum.
According to the creator of these controllers, Craigyb:
"So when I was 16 (around 45 years ago) I used to dream of the Arp Quadra. A friend of mine who wasn't a keyboard player, but just wealthy bought one and it was sat in his front room doing nothing unless I could call around after school and have a play on this great synth.
Now I know I could probably afford to buy one, but the wife would kill me quicker than the Russians, so instead I took Cherry Audio's VST of the Quadra and created a physical beast with a PC built in to create sounds.
I then followed that up with a synth that I've never met in real life AFAIK but is also quite legendary, the Elka Synth (again a VST emulation by Cherry Audio).
I'm currently working on the Memory Moog version (MemoryMode by Cherry Audio) and I just need to finish the actual hardware as the software controller is complete."
Further below are a few more creations from Craigyb in a separate thread on the Sequencer.de forum here.
