mmmmmmmmmm seems to be a procedure error. to try different presets i used a midi track already recorded and tried to audition the presets by changing them playing the midi - play, stop, change patch, play. just as i would with a midi instrument loaded in sforzando.

it does work if i use the RB piano to trigger the synth - play a note and hear the patch, change the patch play another note and hear the new patch.

maybe that's how this synth works. tablewarp2 works differently - more like a midi instrument.

i'm looking for a synth sound for a friend's song - he wants a motif of 'a leaf on a stream' so maybe i'll be just as well to use one o the GM2 synth or pad sounds played as midi, transferred to audio and worked on with plugin fx!
