Shoryuken Posted August 20, 2015 Report Share Posted August 20, 2015 Hi, I'd like to add some expressivity to my MIDI keyboard plugged into the Retrocade Synth when I play SID sounds Is there already a way to get a vibrato, a portamento or a fast-arppegio effect ?If not, I think I will try to recreate those effects by writing some functions using a timer, varying the frequency etc... But before I go this way, I wondered if the SID instrument could not do this natively ?I don't know much about SID specifications but in the software GoatTracker (SID tracker), the instruments implements already those effects. Also, each intrument refer to a "wavetable" that allows (among other things) to make those typical fast-arpeggios Is that different in the Retrocade Synth ? What would you recommend me to do ?

Jack Gassett Posted August 21, 2015 Report Share Posted August 21, 2015 Hello, I'm pretty sure those things are done in software in GoatTracker, they are not native to the SID chip. I remember at one point I found some source code for an open source SID implementation that had the code for those effects and I thought it would be easy to add them to the Retrocade code... Jack.

Jack Gassett Posted August 24, 2015 Report Share Posted August 24, 2015 TinySID source code maybe? I looked at a lot of SID source code so I don't remember exactly... Quote Link to comment Share on other sites More sharing options...
