eptheca Posted June 22, 2011 Report Share Posted June 22, 2011 (edited) Hi, I'm finnishing my first MB project, a stereoSID with 8580 R5's, minimal CS, 5 analog pots and feedback mod I have a problem with the feedback only working in the left channel. I have RTFM, checked wiring, pot, connections, SID's and have enabled EXT audio in filter I am just starting to learn this synth, so I was wondering if there is something else I have missed in the settings for example If you have any suggestions, I would greatly appreciate it :) I'll also take the opportunity to thank you TK for this fantastic synth, and framework. It's not just a cool thing, but something that has improved the quality of my life, and hopefully will continue to. Thank's also to all forum members, none mentioned none forgotten, but you know who you are. Very inspiring to follow your work.

sidmonster Posted June 22, 2011 Report Share Posted June 22, 2011 It must be your wiring. Are you using a single stereo pot for feedback, or two mono pots? Please photograph the connection of the wires on the jacks, pots, and sid modules specific to the feedback mod and repost so we can verify.

Hawkeye Posted June 22, 2011 Report Share Posted June 22, 2011 (edited) You can try swapping the SIDs in order to verify that it is not them (unlikely). To make the effect more audible for testing, choose a bandpass filter and turn up the resonance. Here is a link for the cabling necessary for stereo pots: Edited June 22, 2011 by Hawkeye Quote Link to comment Share on other sites More sharing options...
eptheca Posted June 22, 2011 Author Report Share Posted June 22, 2011 thanks guys I thought maybe there was something in the settings I had missed out I had allready checked the wiring and the SID's next on the list was the solder joints, and there it was on the audio in el.cap. :) sounds amazing now glad I added a volume pot before the audio out, it can get pretty mean Quote Link to comment Share on other sites More sharing options...

eptheca Posted June 23, 2011 Author Report Share Posted June 23, 2011 here's the rest of the pics of the synth pretty straight forward stereoSID with modules from SmashTV, 8580 R5's, minimal CS with 4x20 LCD, 8(7) banksticks, 5 analog pots, 500K stereo pot feedback mod, stereo volume pot, front panel from Schaeffer and rubber knobs from eagle (Mauser) all cased in a Sinclair ZX Spectrum + 48K computer case from 1984. I'm looking for a different knob for the menue encoder. Quote Link to comment Share on other sites More sharing options...
Hawkeye Posted June 23, 2011 Report Share Posted June 23, 2011 it looks great - i love the button caps and the spectrum colorz :-) Quote Link to comment Share on other sites More sharing options...
jojjelito Posted June 23, 2011 Report Share Posted June 23, 2011 ZX Spectrum cases look fantastic still in this day and age. Spectrum 128K with the visible heatsink looks like expensive UK hifi gear. Congrats on your build! Quote Link to comment Share on other sites More sharing options...
