Fix MIDI audition and audition seeking

Browse Source 
DiskReader::seek() no longer fills MIDI buffers.
MIDI is now read into memory via DR:overwrite_existing_buffers()

There is still some edge-case remaining to be fixed. For
some reasons the synth does not receive initial patch/program
changes when starting auditioning.
