There are a few terms that need to be understood before you can unlock the DP /4' s full potential
as a programmable effects processor.
Algorithm An algorithm is the basic signal processing building block in the DP / 4. The word
"effect" could be used instead of algorithm, but some algorithms can produce several
sonic effects simultaneously. Each algorithm has a set of parameters that control the
effect(s) it produces. The values of these parameters are saved with the algorithm in
presets. Each DP / 4 algorithm has a three letter abbreviation which helps to identify it in
Select Mode. The DP / 4 Algorithms are:

By-pass Units The last parameter of each Config Preset gives you two choices of how to mute effects.
Chorusing
When set to "bypass," pressing two times on a Unit button (red LED is lit) will cause the
effect processing to be temporarily silenced for that Unit, so all you hear is the dry source
signal. It
bypasses the algorithm/Preset. "Kill" is the other choice (see Kill).
An audio effect that takes place when a source signal is combined with time varying
delayed versions of itself. These multiple delay lines create phasing characteristics that
make the source signal sound wider/bigger. Usually delays of 10-30 milliseconds will
create pleasant choruses.
Compression Ratio The amount by which a signal is compressed. For example, a 4 to 1 compression
ratio means that the signals that go above threshold are attenuated by 25 per cent. At
high ratios (like 20:1 and above) the compressor acts as a limiter.
