I create a new blanc session. Then two empty mono tracks.
I choose input 1 for the first track and input 2 for the second track.
On the first track insert I load Waves GTR3 tool track mono/stereo and choose a preset for guitar.
On the second track insert I load a second instance of Waves GTR3 tool track mono/stereo And it´s all fine.
As soon as i choose a preset for bass everything goes to hell. A very loud distorted sound is all i get and this goes one until the second insert is removed.
This happens with or without track monitoring active.
I´ve tried this on windows 10 pro and windows 7 pro both 64 bits with the same results.
My audio device is a M-Audio profire 610.
My pc: Asus p6t. Intel I7 920. 12 Gb of triple channel DDR3 1600. Nvidia gtx 970.
I also tried this on pro tools M-powered 8.05 and everything was perfectly fine.
