Absolutely wonderful equipment! I've been experimenting a lot recently with connecting various external inputs to 2600 (above all, it's great to generate a CV or Env signal with the help of the PC's outputs - it gives a lot of production possibilities) - I'll definitely write another post about it soon (also in English), but I don't know what to focus on yet. I could for discuss every single module in it with a visualization of what it does, though that would probably require more of a series of articles :P I love ARP synthesizers - they are hilarious! <3

By the way, I see you write about synths too - I'll be watching your stuff ;>
