MMF's sound is killing me :P

I have Sound/Music/Ambient controls for a project that I'm working on. Channel volumes are not carried over to every frame. Fine, I'll just reset all channel volumes to what they should be at the start of every frame... MMF crashes. Okay, I'll try resetting the volume a little bit after the frame starts... now there is a noticeable clip. Master volume is useless to me because there are three types of sound that are being played. Do I have a lot of sound effects that are being played on each level? Okay, have to reset each channel's volume right after a sound is played, but then there are noticeable clips when the sound is played before the adjustment is put into place.

I've asked Clickteam before if they would consider making changes but it works as intended. :( If we could group channels and then assign permanent volumes to those groups that would be great. Channels 1-10 volume is set to 50 over all frames. If we could give a range for samples to play in that would be great. Play sample from channels 1-10.

Please don't say "it works fine for me." I know Niff has had similar problems with MMF's sound system.

Can you provide an example file of the crash?

I tried to make an example, but the code that makes my project crash does nothing to an empty application :/ All I'm doing is changing all of the channel volumes at the start of frame.
