I'd like to report that the Prophet-VS has been displaying a little instability in Pro Tools 8.0.4 on Snow Leopard 10.6.3. While working with NI Massive and the AIR Transfuser on other tracks in a session the Prophet was changing presets on me on an instrument track...then the delay timing was off while playing back the session even with the sync on both the delay and the LFOs. If I went back and played the Prophets' midi region again it would be in time....but I find I keep having to do this.
