[PD] legato portamento

[Simon Iten]

dear list,

i try to make a monoponic bass synth patch that glides from note to note, but only when more than one note is pressed.
here is my attempt that works, but if i play very fast i get stuck notes and a stack overflow error. this seems to come from the counter. when i remove the counter part it all works as expected, but without glide...

is there something wrong with my approach? or is there a better (more stable) way to do this?

cheers
