I downloaded and ran MIR 24 before I read the owners manual. The system was running at 48K. It seems to be working OK.
In the owners manual it states that MIR 24 ONLY runs at 44.1K.
Is some sample rate converting going on?
Can you explain what happens withs systems running at 48K?
Most professional composers run their systems at 48K, the standard for film and TV post production.
