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 ?
