yes denis, that would be a very nice aproach to it.
-every grain could be externally trigered by an lfo or oscilator.
-in case of a grain processor a separate triger for recording and
another for playback so pitch could be controlled by two ways.
-a cv input to control the playback direction of the grain
-a link connector could be included to add more grains if more
complexity is be needed.
