Jace Posted June 3, 2014 Report Share Posted June 3, 2014 Hypothetically, the Audio In function of the MIDIBox SID seems really intriguing, but I can't seem to find any concrete sound examples of the feature in action. What sorts of implementations have you guys tried/recommend? Quote Link to comment Share on other sites More sharing options...
Altitude Posted June 3, 2014 Report Share Posted June 3, 2014 Honestly, beyond using as the feedback loop, I've never really seen anything cool done with it Quote Link to comment Share on other sites More sharing options...
jrp Posted June 3, 2014 Report Share Posted June 3, 2014 If you start experimenting it is important to use a cap to ac-couple the signal to the input. SID input pin is floating at half supply voltage, not ground. i am designing the rest of my analog signal path right now, so this has to wait a little, but i am interested in trying. Basically it allows you to process analog signal like drumloops with all the goodness the SID (or external voltage controlled effects) have to offer. So it´s really cool! I already implemented this with my external filters. You can imagine what you can do with a drumloop, tempo synced LFOs and envelopes, using filters, distortion and vcas.... I expect the sound of the sid input to be a bit grainy compared to using an external filter. Maybe it has a cool vibe to it when going beyound the 2vpp signal level pointed as maximum in the datasheet. And the sid filter of course... I definitly want to check it out, but as i said, for now i am at the other end of the signal chain so to speak. About feedback: With my 6581 this does very little but adds a bit of grain, distortion and boost you might find pleasant. 8085s will go into oscillation when in BP mode. I decidet not to implement it as i am using external filters and a lot of much more powerful voltage controlled processing so it had no reall benefit to me. If i would implement it it could be considered to use a fixed feedback level. At least for me i had the feeling this was more of a turn on turn off type of effect. - In other words, my pot during experimenting was either fully up or down when playing with this.

TK. Posted June 3, 2014 Report Share Posted June 3, 2014 I'm using the feedback option in almost all bassline demos, e.g. in this one: http://www.ucapps.de/mp3/midibox_sid/mbsid_v2_tk2_soundbank_demo.mp3 However, the signal/noise ratio is very poor, which means that the option will only work for loud music... ;-) Best Regards, Thorsten.

jrp Posted June 3, 2014 Report Share Posted June 3, 2014 the demo makes me think i should give feedback another try.... like the scream it gives. Quote Link to comment Share on other sites More sharing options...
