Thanks for the reply's guys! I've checked out the PICSynth filter... It seems cool. I've done a bit of research since I posted this and it sounds as though even with the correct voltages, the Synth ...

Hey guys, I'm more of a lurker than a participant in threads but this has been a tough one for my n00b studies of synth circuits. I've been building and studying Nicolas Woollaston's (Nicolas3141) m ...

Hey Nicolas, in that CGS controller schematic, would any components need to be changed when using a bi-polar 9V PSU or will it work as is? I'm just curious because your controller is missing the Gate ...

Thanks so much Nicolas!! This is awesome! I'll let you know once I've got it built and tested!

Cheers,

Does anyone know of a really "simple" V/Hz keyboard controller circuit for these? There are a few around for 1V/Oct (MFOS comes to mind) but nothing more or less "simple" for the ...

Yeah, the ribbon controller works as it should and is connected to 0V and +12V... Still humming. I wonder if maybe the Transistor is going bad? I'm using the BC557 instead of the 559 and I believe ...

Hey Nicolas, Thanks so much for the reply!! I noticed that the tri output doesn't have any hum during and for a second after a note is sounded but if no voltage is supplied to the ribbon, the tri out ...

Hello! Sorry for resurrecting an old thread as my first post! BUT, I just built this lovely little VCO and am running it with a +/- 12V PSU. It works great although, I seem to be getting a pretty n ...
