It's a calculator for working with samples and music, built as a companion app for the Polyend Tracker+.
- Calculate how long a [step/beat/bar/pattern] is at a given BPM
- Calculate the BPM of a sample by it's length
- Calculate required pitch shift to stretch a sample to a given BPM
- Calculate new BPM by pitch shifting amount
