Slow to get back on this as I’ve been away…but I’ve worked through some options, and what I’ve determined may be useful to others:
There is no straight 4-channel export option, and thus no immediate way to turn the 2 stereo IR files into LL/LR/RL/RR 4-channel file REVerence is looking for as “True Stereo.” 4-channel output buss options are LRCS and Quadro and in both cases, assigning them as the output busses of the 2 stereo channels results in an exported 4-channel file with all audio on the first two channels and no audio on the second two channels.
By doing a “Split Channels” export of each of the stereo files in order to have 4 mono files to work with, you can use the Quadro buss and export a usable 4-channel file. The question then becomes, which is the correct way of assigning the four Quadro output channels (Left, Right, Left Surround, Right Surround):
A) LL to Left, RR to Right, LR to Left Surround, and RL to Right Surround.
B) LL to Left, LR to Right, RL to Left Surround, and RR to Right Surround
While A “looks right,” according to the Plug-in Reference Manual (page 43), B is correct for working in a stereo recording, because REVerence reads channels in the given order below (my asterisks):
No. of input channels (followed by) Channel order in REVerence
4 L/R/LS/RS (if inserted on a track with a 4.0 channel configuration)
4 LL/LR/RL/RR (if inserted on a track with a stereo configuration)
6 L/R/C/LFE/LS/RS (LFE is being ignored.)
And if I am reading the manual correctly, REVerence will by default work in true-stereo mode when inserted on a stereo track, when utilizing a “B” arranged 4-channel IR file.
- I also exported a stereo file mixdown of the 2 original stereo IR files. Interestingly, this seems to work better with a mono channel when REVerence is on a send. I tested all of this with a vocal track routed to a group channel, switching enabled sends on the mono vocal channel and the stereo group channel and auditioning the the different file versions of the IR.
So, it looks to be a lot of effort processing well over a hundred different verbs in Samplicity this way, but the quality is definitely there, gratis.
