Description
Also adds a sequencer-programmed arpeggiator, new polyphonic voice allocation algorithms and flexible hold-pedal behaviour. Some original features are cut to make room (the sequencer holds 30 notes instead of 64). Presets saved under Loom do not load on stock firmware and vice versa; run INIT after switching. The author says installation is at your own risk.
