Yep, autosave is crucial. I had hoped this sequencer would be a tool for dynamic performance and improvisation, much like the Elektron style of sequencing - however as it is now, where losing your work is the default behavior upon switching patterns, I find it to be extremely rigid and limiting. It doesn't lend to dynamic improvised performance - instead, it lends to pre-prepared sets and pressing the Next button. I might as well use Ableton and my own controller. Auto save is crucial. I hope it's possible and slated for the next update.
