I have forte dxi 1.6 and coyote WT 1.1 and the problem appears on SOME Midi files regardless of which DXI sound module you use. The condition does not appear with every Midi file, and I don't know what the "trigger" condition is. This test Midi file plays OK on VanBasko's player, Quick Time, and PG Music's Power Tracks 2011, but it will not play all tracks (only two) on Real Band. It would appear that somewhere in the software handoff routine from Midi file to DXI sound module there is an intermittant disconnect.
