I'd like a +5v on there for my VCDOs :-)

sounds quite reasonable.

yep.

yep, i'm bored of moog, one of the ARP ones or a good SVF.

> VCA - any

a good quality one, the VCA tony allgood uses in his tripple VCA is 
fantastically good and really low noise.

Yep,

> Noise -

noise with S&H, seems a waste other wise.

Myself, i'd like ;-

VCDO - 256 waveforms
VCADSR with variable slope types (log, exp, rev log, lin, etc)
Dual VCLFO
Quad VCA with a single input, handy for routing those CVs around!

Www.arptech.synth.net

Thats the problem, the cost of manufacturing them.
