What is the most wanted feature you would like ?

  1. Easier way to assign a mod set to all samples in the instrument, maybe right or middle clicking the button where left clicking only does one sample at a time

You can use modifier keys like shift and or ctrl while mouse clicking samples to set more than one mod-set at the same time.

  1. Song > expand, expands all patterns and adjusts LPB accordingly. Wouldn’t be surprised if there’s already a tool for this actually, should look into that…
