I’ve come across this thread which explains my issue more clearly:
https://forum.renoise.com/t/help-with-working-with-long-samples-like-guitar-tracks/28436
I think I will try to use JACK transport to “rewire” Renoise into a horizontal DAW like ardour for the tracks where I’m doing long guitar samples. Or maybe I will try rewire.
I tried snapping to beats and that works and all but it’s still a tedious process. I’ll also take a look at the tools page and the tools API to see if there’s some way from the API to slice a sample into a preset interval of time. Chop-sample is close, but requires the sample to be the exact length. I guess I could pad out samples to be the exact length and use that as a workaround - but I think maybe ardour/renoise might be a better thing to try. Thanks
