Section 3 - Editing Effects
Choruses, delays, reverbs, phasers, flangers, and pitch shifters all rely on a combination of dry
and effects signal to produce their characteristic sounds. A good example of this is a chorus. A
chorused signal by itself (without a dry signal mixed in) sounds like it's slowly moving in and out
of tune (a dry signal is, of course, just a plain signal). Only when you combine the modulating
signal with the dry signal, do you get the dynamic detuning sound you know as a chorus.
Even simple chorus pedals use a 2-input, 1-output mixer just before the output jack to combine
the wet and dry signals. The GSP-2101 Artist, on the other hand, separates the effects from the
mixers to give you maximum flexibility and control over signal flow.
There are other reasons why you might want to use mixers, especially in multi-effects setups. Fig.
3-12 shows a basic multi-effect Algorithm you can easily set up in the GSP-2101 Artist. As you
can see, the signal passes straight through all the effects to the outputs with no dry paths except
the Master Mix control (set at 50:50). Without mixers in place to carry the dry path around
each Module, you would hear the dry signal immediately at the outputs without effects (because
of the Master Mix path). One second later, after the delay has run its course, you would hear
delay repeats with chorus and reverb.

Although perfectly acceptable, this typically, is not how you want your effects to behave. Logic
dictates that you should hear sound at the outputs with chorus, delay, and reverb as you play.
Thus the need for mixers.
Fig. 3-13 shows the same Algorithm, except that instead of running the Modules in straight
series as shown in fig. 3-12, mixers are inserted to carry signal around each individual Module
and into the next.

When you use mixers in the Algorithm, the input of the delay gets a combined version of the
chorused signal and the dry signal. Likewise, the input of the reverb gets a combination of the
chorused, delayed, and dry signals, while the Master Mix gets a combination of chorus, delay,
reverb, and dry, giving you the complete sound at the outputs the way you would expect.
NOTE: The easiest way to control individual effect levels in multi-effects configurations is to 1
run the Master Mix control at WET:100, mixer levels at 100 and adjust individual
effect levels at the Modules themselves (e.g. CHORUS LEVEL, DELAY LEVEL).
