Minim play, record, save in sequenced loop

Can anyone help -I am new to processing and I am trying to create an experiment protocol which includes a part in the draw function that when called will loop through a sequence of play-> record ->save etc. until a set number of recorded files are saved.

This is part of a longer code so I have simplified it here to just the minim play/record issue, but it is why I am trying to keep the draw function clear.

Current Problems: 1. Record does not start at all. And in earlier iterations record was starting but when it tried to save there was an error. 2. I'm at a complete loss how to control the play->record->save loop for a set number of times before returning to the Draw function.

I hope someone can help -I've been trying for days now :/
