Applications for Writing Songs
Most music applications can be used to create songs for the Mobileer synthesizer. You can use your favorite sequencer, staff notation editor or other music program to compose the song. Then export the song as a Standard MIDI File.
An inexpensive ($20) but very powerful program for composing is Melody Assistant by Myriad Software. It is an easy to use staff notation editor that supports other forms of note entry including drum grids and tablature. It can export SMF files in General MIDI Format.
Most other music applications including Cubase, Cakewalk, Logic, Finale, etc. should also work fine.
