LGB Posted December 27, 2006 Report Share Posted December 27, 2006 Hello,I'm an enthioustic DIYer, I like the C64 but I know little about synths. Well I know one thing, I like them ;)I'm thinking about building a MIDIbox SID (which shouldn't be a problem, I've got enough experience) but I don't know what are the advantages of step B (multiple SID's). I suppose you could mix the sounds or something so that you can create more sounds, but I'm not sure...Also am I right that the MIDIbox SID is polyphonic by itself (even without multiple SID's)? I'm wondering how that's done, I know the SID has 3 oscillators, for a nice sound you have to use at least 2 oscillators I suppose, so how can you make polyphony out of that?And another question, how are the the additional LFO's and envellopes generated? I suppose by the software in the PIC? Quote Link to comment Share on other sites More sharing options...
DrBunsen Posted December 27, 2006 Report Share Posted December 27, 2006 what are the advantages of step B (multiple SID's).Well, each one can store and play a totally different patch, and can also be modulated differently by the PIC engine, as well as playing a separate melody over MIDI. So it's effectively a completely separate additional synth in the same (or a different) box.polyphonic by itself ... 3 oscillatorsEveryone's idea of a nice sound is different. ;D You can sequence each oscillator separately, so you have the choice of playing 3 single osc voices (through one filter) or one 3 osc voice, per SID.additional LFO's and envellopes generated? I suppose by the software in the PIC?Yup. Quote Link to comment Share on other sites More sharing options...
LGB Posted December 27, 2006 Author Report Share Posted December 27, 2006 Oke cool, but with 1 SID and using 2 channels per wave polyphony can't be done I suppose? Quote Link to comment Share on other sites More sharing options...
DrBunsen Posted January 7, 2007 Report Share Posted January 7, 2007 I don't know what you mean by two channels per wave. Quote Link to comment Share on other sites More sharing options...
