I had this same problem on a Pentium MMX 233 with an Aztech 2320 based card. I checked the MIDI IN pin with an oscilloscope, and it had full amplitude high frequency noise on it. My hypothesis was that the level converter on the WP32 could not handle the high capacitance on the MIDI IN line of the …

It seems unlikely to be a software issue, as MIDI IN is purely an input, so there is no way for MUNT to change it. However, the level converter on the WP32 is bidirectional, so could have an effect.

Hey, could someone provide some support with the McCake? I installed mine on a YMF719E-S Yamaha soundcard. If I setup a game to use it as a midi device and then test it, it might work for a short while. But then it starts going crazy by playing random sounds all the time (it sounds like an …
