This sounds pretty good to me:
They sound unreal and I'd like one.
The MIDI "issues" with the Circuit I'd hope are more pronounced considering it was supposed to be a sketch-pad with some DJ type usage also. It's a lot of fun and I'd still have bought it (2nd hand at half the store cost) if I knew there was a crappy MIDI implementation. It's not a "real" synth, I'd put it in the realm of drummachine if anything and the very crappy MIDI doesn't impact upon it's ability to blow a hole in your wall. It's weird how Novation work, they made some of the best MIDI controller, some of the few on the market that can transmit 14bit NRPN's with simple programmers that are not even needed really as it can all be done from the front face.
I've just had a look at the MIDI parameter list for the Peak, it's the same mishmash of NRPN's and CC's. They are listed in parameter order and they don't mention if the NRPN's are in hex or dec and what the hell is 0:2? It's supposed to be an NRPN number but it's a ratio, so again back to is it hex or dec?
Part of me was sure they wouldn't make it so cryptic with a real synth. They must think we all have 12 arms and can play four synths at once while tweaking dials so have no real need for that silly MIDI stuff...... I wish I could say I've dealt with worse, but I haven't.
I still want one, it'd probably become a performance machine as it needs to be tweaked live if it is to be at all with any ease. Nothing can ruin it's ability have a sequence of notes shot at it via MIDI, so at least that part would work as with any other MIDI instrument/module.
