Works on PalmOS 3.0 and higher.
Can be used as a stand-alone, editor-like monophonic sequencer on your PC.
You need a MIDI synthesizer to play data ('software synthesizer' works fine).
Ability to export data to SMF (Standard MIDI File) for other 'normal' sequencers, as well as to PDB (Palm Database File) for Monody Palm.
You don't need a MIDI systhesizer for this function.
