Hey everyone,
I just thought of an interesting idea. Since the SK samplers operate their voice ADSR envelopes using a simple CV line for each voice from the processor, and the maximum voltage of that CV signal determines the volume of the VCA, it would theoretically be possible to attenuate or boost that CV maximum voltage "on the fly".
I was thinking of how it might be done, by imagining some kind of velocity or pressure resistance switch added to the keys that basically put a variable resistance in series with each CV line. And so if you strike a key slowly, it throws a higher resistance in the CV line, and so a quieter note is played. Hit it harder, and the resistance is lower, and the louder the note. Actually, if a pressure switch was used, it would create aftertouch. This actually seems easier to do than velocity (I'm thinking of cheap, easily bought available parts here) as pressure conductive rubber sheeting is readily available.
Has anyone got some thoughts on this? it would be pretty strange to have an SK with a velocity or aftertouch keyboard
Cheers, Graham
