I've been getting a lot of stuck notes with Atmoshpere for a while now (years) and I'd like to try and solve this. Non of my other soft-synths have this problem. Here's my scenario:

Roland GI-20 guitar to midi converter- via USB
Mac G5 dual 2.0
Pro Tools HD 7.1
Atmosphere 1.2 running RTAS (of course)

I know that having a controller in "local" can cause this but I don't think that's an issue with the Roland guitar box. Anyone else have this experience with Atmosphere? Could it be a buffer set too small thing? Thanks! Eric
