I tried to respond earlier but not sure if the message made it.
Yes, the ROMs have the waveforms in them. I tried testing all I could but its nice to get some bug reports from the field. It is possible some of my code and some dumb stuff I did at the end of the ROM may have screwed up the silent wave. I've been optimizing the original code and mine, so all my hacked code at the end of the ROM will be moved anyway. Once I figure it out I will send out the new version free to anyone who has already bought a copy. Sorry about that!
