Seems I must have leant on my Maudio and switched the midi channel over. I now have Zynaddsubfx working again. Still no progress on the Soundfonts though. Although it does seem to be worse with some soundfonts than others. Maybe it is just the soundfont.
That being said, I have tried it with Qsampler (linuxsampler front end) and the messages window seems to be saying something about maximum input being exceeded when I press a key on the Maudio. I didnt really think about the significance of it until after I had shut down. I'll captur the message later and post it up - maybe it has something to do with the problem.
As for me and Tango - for now we're trying to talk through our problems. (I'll keep my feet off the sofa is she quits complaining).
EDIT: Heres the message from linuxsampler when pressing the keyboard keys:
Using one of the fixed velocity settings on the Maudio irridactes this message and results in a stable key velocity (meaning I cant use velocity for expression etc but at least dont have it dropping to an inaudible level).
sf2: GetInitialFilterFc() is above the maximum allowed value (max=13500): 27000
Could it be Im just a ham fisted troll with equipment vastly superior to his skill?
EDIT2: Seems that the error message is dependent on which soundfont I am using. Some have it and some dont.
