hear bass sound on the gtr trk but the wave is gtr
 

I use HD1 on a G5...I always apply many many plugins on my trks...i usually have about 32 trks in a session. I have an example of the problem here:
Sometimes i apply different HTDM plugins on both Bass and gtr (with a lot more plugins on other trks as well), the gtr sound suddenly disappear and the sound of bass trk replace it.....the wave is still the gtr waveform, but bass sound is played instead.....it seems no such problem on TDM plugins but only appear on HTDM......

Sounds like two tracks sharing the same voice....

Sounds like bad DAE, have you trashed all the regular stuff? If you have and it still happens, Do this:
0. first copy your plug ins settings folder to you desktop, this will make a copy of your presonal plug in settings.
1. From your Pro-Tools install disk, open the DAE folder , drag the new DAE icon onto your desk top.
2. Go to your Pro-Tools folder inside your applications folder.
3. Remove the DAE Icon and place it in your trash can, do not empty trash.
4. Replace the DAE on your desktop to you pro-Tools folder where the old DAE icon lives.

Now boot up Pro-Tools session and see if this fixes your problems, once it works then empty your trash can. Good Luck!!
