Pro Tools 9 and Reason 6 get out of sync with buffer change, ideas?
Hi,
I'm having a problem and would really appreciate if someone could assist me. I'm running Pro Tools 9.0.3 and Reason 6. When I play a song (even just a couple tracks in PT and no instruments in Reason, just watching the timeline) everything syncs up nicely as long as the H/W Buffer size is 256, 512, or 1024. But as soon as I change the buffer to 128 or less, the sync gets off. For example, if I have a certain change that comes in at bar 84, as long as the buffer is set at 256 or higher, if I start before that bar, the change happens at bar 84 when looking at the timeline in Reason. However, if I change the buffer to 128 or less and I start a little before bar 84, watching the timeline in Reason, the change comes too early. I did see where someone else was asking about the cursor speed in Reason. This is another way to look at it. With a higher buffer, the cursor moves quickly (normal) and is synced with PT. With a lower buffer the cursor moves slowly and is out of sync with PT. I searched on here and the Reason forums page, along with google searches. I have performed the General Troubleshooting that is listed on this site along with the setup guide. And I know about running Reason in 32 bit mode, so that is not part of the issue. My specs are: Mac Pro 2.8 GHz, OSX 10.6.4, Digi 003 rack+, Pro Tools 9.0.3, 12 GB Ram, OWC Mercury Elite AL Pro external hard drive for record/playback connected by firewire. No other peripherals are attached. I have spent a couple weeks trying to figure this out myself and I really need some help. Thank you! Paul
