I have Express Scribe Pro, and just installed an Infinity Series foot pedal controller ECS-148649 which was supposed to be compatible.
Although "status" is good after using wizard, when trying to practice on the Express Scribe instruction voice, I can't control the speed
with the slider bar at bottom right corner. Either too slow or too fast.
I have not loaded in any files as of yet. Just trying to practice on the default voice instruction.
