Polly
A pocket arranger for the M-VAVE FM-1
Polly turns the FM-1 into a pocket arranger. It's inspired by the Yamaha QY70. Pick a style, and a band of eight instruments plays along, with drums, bass, guitars and strings. Hold a chord, and the band follows it. Write a few bars of chords, put them in order, and Polly plays a whole song from them. It adds fills, an intro and an ending. The sounds are the 128 General MIDI instruments and a drum kit. They play through the FM-1's speaker or headphones, and MIDI in plays them too.
