Is there any way to use this for classical guitar, for example: being able to put a thumb part and finger part on the same staff with different note values in each part (thumb part whole note-fingers 1/4 notes). I can't find a way to do it, just harmony with the same time value. If I can use it for classical guitar, I'll buy it! EDIT: I take no response as a no, it's not capable of notating fingerstyle guitar. Could have been a guitar composer's best friend on the go.

Bad instrument playback, but has good instrument transposition. Need that if composing a romantic symphony or heading to Musescore or Mozart17 if composing.
