EDIT/DETAILS/FX BUS vs. EDIT/PATCH/FX-BUS [and Multiset Effects]
Here's an item that has confused me plenty in the past. I hope this
clarifies things.
The EDIT/PATCH/FX-BUS window is meaningless--
--unless the FX BUS setting in the EDIT/DETAILS window **for that
particular part-position within a Performance where the patch is assigned**
is set to PATCH as well.
(The settings of the DETAILS page for one part of the eight parts
available has no effect upon different numbered parts, even if its the
same patch but in different slots.)
Any other FX BUS setting besides PATCH on the EDIT/DETAILS page over-ride the settings on the EDIT/PATCH/FX-BUS page [that is, the BUS-A, 99/1 thru 1/99, BUS-B, BUS-C, C + D, BUS-D, and ALL settings over-ride the EDIT/PATCH/FX-BUS settings entirely.]
In a Performance, you could have a patch called, say, DIGI-HARP in both position ONE and TWO, but on the EDIT/DETAILS page, you could route the one in position ONE (PART one) to some mix between A and B, say for instance a 46/54 mix with the FX BUS setting, and the one in position TWO (PART two) to PATCH in its FX BUS setting (which could have one wave of its two assigned to just A and the other wave assigned to B to split the patch into stereo, then).
See the difference? EDIT/DETAILS assigns the whole patch to an output (including the Vector mix) when its FX BUS setting is set to other than PATCH, but when set to PATCH, you may assign individual elements of the patch (its waves or wave sequences) to different output channels than the others. If you had a Vector Sequence that alternated between wave A and B in a loop, and assigned A and B as above on the EDIT/PATCH/FX-BUS page separately to the A and B channels individually, it would alternate between the left-channel wave A and the right channel wave B. You can create an automated stereo pan this way -- but must have the FX BUS setting in EDIT/DETAILS set to PATCH for it to work -- otherwise the Vector Sequencing output will be mixed to a mono source which then can be positioned as a mono source by the EDIT/DETAILS/FX BUS setting into the stereo plane, but it will be a mono-mix of the Vector Mix Envelope that is being routed.
These settings on the EDIT/DETAILS page and EDIT/PATCH/FX-BUS page and the EDIT/PATCH/WAVES/MIX ENV Vector Sequencing page apply whether it is the MULTISET-EFFECTS or the PERFORMANCE-EFFECTS being used. That much stays the same as far as the Performance is concerned, though the effects may be different.
In summation, the signal path can go either of these two directions:
WAVES --> MIX ENV --> (mono mix) --> DETAILS/FX BUS setting NOT= PATCH --> EFFECTS or MULTISET EFFECTS
or
WAVES --> MIX ENV --> (no mono-mix) --> DETAILS/FX BUS setting = PATCH --> EDIT/PATCH/FX-BUS --> EFFECTS or MULTIEFFECTS
Finally, you cannot save on polyphony by switching off waves-oscillators in the EDIT/PATCH/FX-BUS page unless the EDIT/DETAILS page FX BUS setting for that Performance-Part position is set to PATCH also. Setting a wave in WAVES to zero volume does remove that wave from affecting your polyphony, however. Two entries of the same patch in a performance but in different Parts can have different characteristics by virtue of the EDIT/DETAILS/FX BUS setting and the EDIT/PATCH/FX-BUS assignments, as explained above.
