Hi, Newbi question. In X2 I've imported a midi track which seems to have the instrument selection built in. I'm using CakewalkTTS and when I try and change the TTS instrument, as soon as the midi track starts playing the instrument reverts to its original setting. The Bank and the Patch settings on the inspector are not set (bank is ;--- and Patch is None). Where is the midi instrument specified and how can I change it? Thanks, Richard
