cases, instead of a hole, you will hear a momentary pitch shift as the studio changes. A bit of
experimentation will help you determine how to achieve acceptable transitions between
studios.

Figure 15-10 Effect of FX Algorithm on Transition Between FX Presets
Changing PAU Allocations
There are other circumstances under which using the same algorithm will not ensure a smooth
transition. If for any reason the PAUs have to be reallocated when you move from one studio to
another, then even if the algorithms on a given FXBus are the same in both studios, there will be
a ramp-down/ramp-up. This can happen when there is a change in the number of PAUs being
used on any FXBus that has a lower number than the FXBus youÕre concerned with. ThatÕs
because reallocating PAUs on the ßy forces some of the processors to reconÞgure themselves,
inasmuch as they are now being called upon to do different functions.
HereÕs an example: say Studio XÕs FXBus1 uses a Flanger that requires 2 PAUs, while FXBus2
has a small reverb that uses 1 PAU. In Studio Y, FXBus1 has a Chorus that uses only 1 PAU,
while FXBus2 uses the same small reverb as Studio X. When you switch from Studio X to Studio
Y, one of the PAUs that was previously being used for FXBus1 is now being used for FXBus2Ñ
itÕs been reallocated. Since itÕs not the same PAU thatÕs handling the reverb, the transition isnÕt
going to be smoothÑeven though the algorithm hasnÕt changed.
There are a couple of ways around this. First is to set up your studios so that any transitions
between them that are going to force changes in PAU allocations occur in the higher-numbered
FXBusesÑif the situation just described were reversed, and the reverb was in FXBus1, there
would be no problem, because that same PAU would be used in FXBus1 in both studios. A
second method is to manually allocate the PAUs in the lower-numbered FXBuses, rather than
