Nice idea Stu, A friend of mine is already building stuff with chips like that. Not for Doepfer/eurorack yet.. but he was planning to. A module format would make it nice and easy. grtz Ernst On Fri, Jan 15, 2010 at 2:42 PM, wrote: > > > Damn fine idea Stu, > > I know zero about p

I've found the datasheet of CEM3394: http://www.datasheetarchive.com/datasheet-pdf/012/DSA00198797.html There is a diagramm on the last page. It seems that it's probably not possible, is it? Ollie --- In Doepfer_a100@yahoogroups.com, "okmog" wrote: > > Hi, > > does anybody know,

The one i have was new old stock when i bought it, probably a very early one. Anyway i'm only wondering since the clippling level knob seems to act more like its polarised but the knob legend is marked 1-10. Perhaps thats just how it is, any A-116 owners around here? Paul

Thanks for the reply Ollie; I've not explored the feedback loop yet - but I'll definitely give it a try. Glad you're having fun with your A111-5 too ;-) I'm hoping to use the A111-5 in a mini suitcase modular when I've got the time, along with the A190-2, AS RS95e VCO, AS RS380,

yes Stu, I did mean a separate module, so you can use or not if you don't want to. At it's simplest it's a 6 or 8hp module with 4 inputs (plus a through socket for each so you still have your triangle waveform available) and 8 outputs say rising ramp and falling ramp for each inp

Hi Stu, Hi Tim, I hope you are doing well. The observations you have made about the changing phase shifts in dependence on the frequency and resonance value can be explain by Fourier-transformations which is the mathematical theory behind every kind of frequency filtering. It say

hi group, feeding the various outputs of the a108 filter to its own cv and resonance inputs, it becomes immediately obvious that there is more difference here than just slope. i wonder if anybody can tell me what the phases of the outputs are on this incredibly versatile module.
