Reviving this thread as this is a question I wanted to ask as well.
Using an inverted saw to modulate the granular start position (or the sample start position on Sam), doesn’t modulate the full range of the file. Scaling is at 1 on both LFO output and start position input.
I’d like to be able to easily guide the granular through the full length of the loaded file at variable rates to create time change without pitch change.
I’ve noted the same problem with modulating the start point of the sample on SAM, the LFO at full scaling doesn’t modulate over the entire file. Additionally, it sounds different than moving the start point with the encoder. Moving the encoder moves through the file as expected, the LFO driving the start added pitch changing artifacts which I wasn’t expecting.
