It appears the server containing my primary synth site has crashed, and as it's on the other side of the planet to me, there's nothing I can do but wait. In the mean time, there is an older version at: http://otherunicorn.0catch.com/synth/ I have uploaded the latest construction

2002-03-07 by sasami@hotkey.net.au
A possible modification for the chime board has been suggested by Sean. He was finding the oscillator dampers were kicking too soon. His solution was to increase the 100k resistor on pin 5 of IC2B to 330k. This affect the cuttof point of both dampers. Ken ________________________

THe super psycho modulation source PCB and the Master Divider boards are now officially available. I'm completely happy with the master divider, so I am offering this batch at half price, as a "beta" board for those who want it. I still have to test the gate to triggert converter

Hi all, The Lorlins rotaries are great. Snug and beautiful. Regarding the dual psycho MOTM-format panels: I'm ordering some dual psycho designs from Schaeffer, one for me, two for another, but I'm ordering five because of the 10% discount and I figure _someone's_ gotta want 'em.

The Lorlins are on the way from Mouser as we speak. I'll let you all know. I just wanted to say the Xicons didn't work because I listed them on the 'Yank parts list' even though I qualified them and the Lorlins as 'untested'. ----- Original Message ----- From: sasami@... To: cgs_

My thanks to Ken for designing and pcb'ing a great little module. Finished it this evening and spent some time trying it out on e.g's, Klangwerk, filter 'rings', and a few other patches. Duration and End are definitely useful features. I'm sure I've just touched the surface of it

For those who were asking about the DCO, I've got the schematic and PCB artwork online now, in the modules section. Beware though, the module is not as yet tested, nor the diagram error checked. My prototype, which was hand wired, and only 12 bits long, did work quite well. Ken _

It is for driving Wavetables. It's a fairly crude brute force implementation - a 16 bit down counter running from a crystal. Depending on the chip type chosen, it should operate with a crystal well over 50mhz. It is primarilly for my own poly synth, which has been an ongoing proj

I tried your suggestion using 5.1K resistors. Nice! Adds just the right amount of extra range. One request I have for this PCB - if you re-release it, please add an LED driver on the main PCB. A driver for each oscillator would be even nicer. Emitter follower circuits don't take

Tonight I finished my first psycho LFO. I made a few modifications: 1)put a 1 meg pot on every oscillator, copying the circuit for the lowest one on the schematic. This provides a great deal of variety. 2)I found the 1meg pot/2.2uF to provide too much slew, so I changed the cap t

I see your point, a plain pot is not the way to go. If it can be done, an encoder would help with patch accuracy when programming and can add to performance capabilities, you can sweep a knob but not a button. I have gotten a peep out of one of mine with an Evenfall vco as a driv

There is something to say for the wavetable wave select as it stands too. As waves are grouped by tonal quality, advancing the wave in sync with a sequencer gives great tonal sequencing. Replace that with a a/d converter will pretty much kill that ability. Encoders would be great
