Well I feel pretty uninventive after reading some of the other uses in this thread!
After having a Nord Lead 2 and the Octatrack for a while, I realised that they were the perfect pair! NL2 has 4 mono outs, Octa has 4 mono ins. I have the octa organised thusly:
Tracks 1-4: Thru machines for NL2
Tracks 5-8: Samples and whatnot
Cue outs: reverb send (currently using Valhalla vintage verb as I don’t have a hardware reverb)
I decided to make a collection of songs using just this, or try at least. I’m going for 6 tracks minimum, with one “complete” and a few ideas on the boil. I set myself this target as a condition before I’m allowed to buy any new gear, so there’s an incentive. The setup kinda lends itself to electro sounding stuff and that is indeed where it’s heading sound-wise.
Happily, the Octatrack can just about sit on the right hand side of the NL2 panel, so it’s quite a nice neat little setup
