If anyone's got a decent link to that, it may be a neat idea.

did stumble across a page a few weeks ago, however - in my haste for more info, didn't bookmark it!

:(

computers - they're all a bit alien to me.

Will you ever be offering the service?

Post by: Circuitbenders on February 07, 2007, 01:07:47 PM: well, we've been promising it for about a year now but we hope to have a standard set of SH101 mods available this month. They will include all the mods in the guide plus an LFO trigger input if we can find a source of DPDT switching jack sockets and possibly an envelope to VCO pitch control.

Post by: Circuitbenders on January 15, 2008, 07:09:10 PM: Well that all depends on if we are about to have an ebay based bidding war doesn't it ;)

but yes, outside of the sequencer part, most of the 202 synth circuit appears to be virtually identical to the 101. You might need to do a bit of schematic comparison to make sure of positioning but the same kind of mods are definately possible with the 202.

Post by: Signal:Noise on January 16, 2008, 06:48:35 PM: You're safe there Paul, I'm completely and utterly skint at teh moment, but i do wnat some nice roland analogue action and teh idea of an MC-202 with the extra mods is rather tasty.

Post by: Circuitbenders on January 16, 2008, 07:23:58 PM: Indeed it is, and if people would stop insisting on outbidding me on MC202's and SH09's the world would be a better place >:(

at least my world would be anyway................... bastards!
