bad voice card mp3 uploaded in files section, any advice appreciated!

2008-03-11 by rj krohn

hey guys, as always, thanks for the resource here. just thought id drop a quick line out there to see if anyone may have a suggestion on what is going on with this voice card. the specs on it look like this:

-bad voice is voice 3. mp3 scrolls through 7 voices on different presets, so you can hear the sound difference.
-recently changed IG00151 that drives VCF EG, as well as VCF EG chip.
-VCF and VCF EG trim pots are set to the exact same resistance value as a working voice card, so calibration should be at least in the RANGE of "normal". 
-both HPF and LPF sweep through a range, so both VCF chips and VCF EG chips are at least functioning in SOME manner.

this voice card just sticks out like a sore thumb, somethings gotta be wrong with it. 

thanks in advance for any possible help! -rj
