hijacking this thread for general ciat lonbarde praise:
i recently had the chance to play a sidrassi + cocoquantus. it's such a responsive instrument set!
as usual with peter's designs it's rather intuitive than controlled, but they pair up so well. the coco is just made for the sidrassi.
in fact it impressed me so much that i picked up a sidrassi two weeks ago. :-)
hell yeah, they ARE expensive, but if you consider what's in there:
7 VCOs + 14 VCAs (since it's true stereo) + tuning circuit "analog storage scroll" (i assume: 1 LFO + S&H for each VCO).
and then comes the modulation part, which also might include some VCAs...
Still there's a few things I wished the Sidrassi had, e. g. banana jacks (plus ground) for the barre pressure output (could be used for eurorack playing then
now i'm lusting for a plumbutter and a cocoquantus, but my bank account says "no". (and i'm waiting for a shbobo shnth, which is kind of a digital version of peter's designs)
i believe the wood is half of the ciat lonbarde magic.
but if you can live without the wood, meng qi makes some extraordinary ciat-lonbarde-spin-offs in acrylic cases. he also expands the original designs.
he has a few in his etsy shop: http://www.etsy.com/shop/zilaihong
but i think he's doing custom work too (which peter does not do anymore as far as i know).
