Program structure for single-size algorithms
Single-size algorithms use two algorithms for each pro-
gram. These algorithms are used for the head and the
rim.
Programs that use a single-size algorithm also allow you
to use
PCM instruments
(PCM sound sources) for the
head and the rim.
You can freely assign these four sound sources and edit
their parameters to create an extremely broad range of
sounds ranging from traditional percussion instruments
to non-conventional ones; even non-percussive sounds.
The signal flow starts when you strike the head; the
audio signal of this strike is input to the head algorithm,
processed by DSP, and sent to the mixer section. At the
same time, the strike’s audio signal is also used to trigger
the PCM instrument, and is itself also sent to the mixer
section. An EQ is located immediately before this audio
signal is input to the algorithm, allowing you to select
the most appropriate setting depending on whether
you're using your hand or a stick to strike the WAVE-
DRUM. You can adjust the velocity curve immediately
before the signal is input to the PCM instrument, allow-
ing you to choose the way that the force of your strike
will vary the volume or tone. For example, you might set
this so that a soft strike will produce only the sound pro-
cessed by the DSP, and the sound of the PCM instrument
will be added as you gradually increase the force of your
strike.
When you strike the rim, the signal flow is similar to
when you strike the head; the audio signal is processed
by the rim algorithm and the PCM instrument, and sent
to the mixer section.
In addition, you can control the head and rim algorithms
and PCM instruments by applying pressure to the head.
The curve can be adjusted for this pressure as well,
allowing you to specify how the pressure will affect the
volume and tone. This can be used to make the instru-
ment behave differently depending on whether pressure
is being applied. For example, you might set this so that
pressure on the head will mute the DSP-processed sound
while allowing the PCM instrument sound to be pro-
duced.
The level and pan of the various audio signals sent to the
mixer section are adjusted, sent through reverb and
delay, and then sent out of the instrument.
Program structure for double-size algorithms
Double-size algorithms are more highly specialized for
simulating acoustic instruments.
For this reason, two separate PCM instruments for the
head and rim are combined into one, allowing a larger
amount of PCM data to be handled.
Within the algorithm, your performance is analyzed in
realtime, and the result of this analysis is used to control
the PCM instrument, allowing a natural response that
reflects your performance in a way that is impossible for
a conventional PCM sound module.
Programs that use a double-size algorithm contain only
one algorithm.
This algorithm contains inputs for both the head and rim,
but this does not mean that they have separate sound
sources for each; rather, the head and rim input signals
are mixed and input to the single algorithm.
Since the PCM instrument is linked with the algorithm, it
cannot be specified independently.
The signal flow starts when you strike the head or rim;
these audio signals are input to the algorithm.
The signal that is input to the algorithm is DSP-pro-
cessed and sent to the mixer. At the same time, the signal
is analyzed to generate a trigger that sounds the appropri-
ate PCM instrument.
The PCM instrument produces sound in response to this
trigger, and the sound is sent to the mixer section.
For the head, you can use an EQ to adjust the signal
immediately before it is input to the algorithm. You can
also use pressure on the head to control the volume or
tone of the algorithm and the PCM instrument. The pres-
sure curve can also be adjusted.
The level and pan of the audio signals sent to the mixer
section are adjusted, sent through reverb and delay, and
then sent out of the instrument.

Audio input and loop phrase playback
The stereo audio signal of the program, the stereo audio
signal from the AUX IN jack, and the loop phrase audio
are finally combined and sent out of the WAVEDRUM.

Here you can set the pan follow-
ing the delay effect, and the volume for the AUX IN
jack. You can also select the loop phrase, start and stop
it, and control its level.
