Play-on-input and Realtime Transposition
Two features I'm really missing currently:
1) The ability to set the song to begin playing (and recording) when I press a note. As it is, if I want to start recording something at the start of the track, I need to wait for it to loop once, since I'm not coordinated enough to hit play and the note at the same time!
2) Realtime transpose! I'd love to have the ability to press LEARN + SCALE to have all the scaled parts of my song change their transposition to the input from a MIDI channel.
