What if the user needs to work with long audio files? For example for mashup/remix purposes, or when working on a collab and importing stems. This seems like an unnecessary and unreasonable restriction
Then the user can match a pattern length, bpm and lpb to a four bars and autoslice the long song sample to patterns using paketti.
use more then 1 pattern & put autoseek on.
or use the `Create Pattern Sequencer Patterns based on Slice Count with Automatic Slice Printing" dialog in Paketti, yep
