I would like to audition some midi files, many of which have a brass track or a woodwind track that has multiple parts on the same track. I can find some instruments in GPO and the JABB that will play polyphonic parts, but many are in Mono mode and will only play a single line.
In trying to find an answer for this, there was suggestion to increase the polyphony of the instrument, but I don't think this applies to the Aria player.]
Is there a way to turn a Mono instrument polyphonic?
Now to the problem at hand. If I understand correctly I think the only way to get accurate playback is to use the player instruments as opposed to the solo instruments.
To tell the truth I'm not sure how you change the polyphony of a patch in the Aria player. I used to do it occasionally in the old Kontakt player but have never needed to do so with the new engine. I don't have the manual handy so I can't give you specific instructions.
