Operation Manual
Noise is a fundamental source for any kind of analog-type percussion, especially
hi-hats and snare drums. Also, wind and other sound effects can be created by using
noise. If noise is selected, you can “color” it with the
Pitch
knob. Negative values
create pink noise (fewer high frequencies), positive values a blue noise (fewer low
frequencies).
The next three buttons don´t set an oscillator waveform; instead, you can choose a
sample for further programming.
Sample 1 contains a closed hi-hat. It can be processed with Pitch and FM and all
other synthesis functions.
Sample 2 contains an open hi-hat. It can be processed with Pitch and FM and all
other synthesis functions.
Sample 3 contains a crash cymbal. It can be processed with Pitch and FM and all
other synthesis functions.

The square, sine, triangle and sawtooth waveforms always start at full amplitude
to create a necessary start click. This is characteristic of drum and percussion
sounds. To avoid this click, simply open up the attack value for Envelope 2 by a
small amount. When creating typical synthesizer sounds you might like to avoid
the flanging effect caused by detuned oscillators. This effect is caused by the fixed
phase of the waveforms. To do this, assign a short pitch envelope to one of the
oscillators.
Pitch Env (Envelope)
-100%...100%
Sets the amount of pitch modulation from Envelope 1 or 2 (depending on the settings).
Positive amounts will raise the pitch when envelope modulation is applied. Negative
amounts will lower the pitch when envelope modulation is applied. Use this parameter
to create time-dependent pitch changes.

Pitch Env
is one of the most important parameters in drum programming because
it simulates the character of a real drum.
Pitch Vel (Velocity)
-100%...100%
Determines the amount of influence the selected envelope has on the pitch, based on
key velocity. This parameter works similarly to the
Pitch
Env
parameter, with the diffe-
rence that its intensity is velocity based. Use this feature to give a more expressive cha-
racter to the sound. When you hit the keys smoothly, only minimal modulation is ap-
plied. When you hit harder, the modulation amount also gets stronger.
The overall modulation applied to the pitch modulation is calculated as the sum of
both the
Pitch Env
and
Pitch Vel
parameters. Therefore you should always bear this
total in mind, especially when pitch does not behave as you expect. You can also
create interesting effects by setting one parameter to a positive and the other to a nega-
tive amount.
