Haven't found this specific problem anywhere and i have been researching since last Thursday so here it goes:
I have set up Reaper to work with Reason via Rewire by following the instructions from Tallisman here:
http://www.cockos.com/forum/showthre...ewire+channels
Here's my problem:
Initially, everything was fine. I was able to lay down 21 tracks of mixed media (VSt's, Reason/Rewire, Recorded Audio). But a few days after I stared tracking, i began to hear the audio from Reason coming through Rewire with cracking/popping/artifacts and dropouts in addition to the transport timer flashing red.
The CATCH is that Tracks 1/2 coming from Rewire sound PERFECT, while anything after that in the chain sounds degraded (pops/artifacts etc..). Even if I switch the instrument from tracks 3/4 and put them on I've tried multiple versions of Reaper/Rewire, I've tried going back to restore points, and I've tried re-installing both programs in different orders. I've tried re-setting up a blank template. Nothing works.
It just doesn't make sense why track 1/2 from Rewire is fine and all the others are jacked. I have tried disabling feedback routing thinking that might be the problem, but that causes the chain and separately routed outputs to stop working altogether.
I am using:
Open Labs Miko LX w/ 64bit- DualCore processor
2 Gigs of Ram
Presonus Firebox (Firewire Connection)
Reason 4
Reaper 2.032 (tried everything from 2.014 onward)
I would site soundcard issues as the potential problem, but my audio card is not PCI, so I don't foresee any IRQ sharing conflicts and Reason works fine on it's own - as does Reaper and any other program.
I guess my next step is to re-install the Firebox drivers?
Any other suggestions/experience with this is greatly appreciated!
