New Features
– Added setting to disable battery check. Mostly for my own benefit, but I built a unit recently where the voltage was reported incorrectly when using USB power. A low battery warning disables saves on the SD card to prevent data loss or corruption, but in this case the warning triggered even when plugged into USB. I’d recommend leaving the battery check enabled except for edge cases like this.

Bug Fixes
– When switching patterns, the final 16th of the old pattern could be silent. This has been bugging me, but I couldn’t pinpoint the issue until I recorded a pattern changeover to PC and noticed the silent final 16th. It didn;t happen consistently, but when it did there was a clear discontinuity when the pattern changed.
– MIDI note durations were too short – now 90% of a 16th. While everything worked fine in testing when connected to PC, I noticed that MIDI notes would not trigger on the M-VAVE FM-1 I was driving. Turns out the note-on events were being sent with a note-off almost immediately after. This behavior has been updated so that note-off events are sent 90% of the duration of a 16th note after the note-on. This fixed silent note triggers on the FM-1. 
– Muting a voice did not mute its MIDI note output. This  one is self-explanatory.
– VELO TO CUTOFF was calculated incorrectly – even 100% velocity would cause the filter to close. I had noticed this odd behavior, but needed to take care of more urgent issues first. It turns out, voice volume was incorrectly being added to the velocity calculation when it should have been independent.
