For my latest large robot project I am using a sound card similar to the MP3 but it plays .wav files instead .mp3 files. Rather than ask for a control for this specific hardware, would you consider creating a generic version of the MP3 Trigger control? This universal matrix control would use the same 10x10 array of buttons as the MP3 trigger, but the user would specify the script command to be exectued for each button push. Besides supporting additional sound boards I can see its potential for other applications. I'm sure other builders might find this useful as well.
