3.1e Oscillators s
The DPM V3 has two oscillators which can draw from any of the 105 on-board
wavesamples (or 10 drum kits). Both oscillators allow for adjustable pitch, level, and
two modulation sources.
Choosing the same wavesample for both oscillators, and slightly detuning them,
creates a thicker sound. However, combining different wavesamples can produce
novel effects. Example: Suppose you're looking for a really deep piano sound; try
adding a bass sample, tuned up an octave and at a much lower volume, behind the
piano sound.
3.1f DCAs
Each oscillator has a DCA, because this allows for, among other effects, crossfades
between the two oscillators. Example: One DCA could fade out a flute sound while
the other DCA fades in a synth waveform for a synth flute sound.
Since each wavesample has a level control, you'll more likely use the DCAs for
dynamic effects than simply setting them to a static volume level. One common
modulation option is to increase the level via keyboard pressure. Modulating with an
LFO varies the amplitude cyclically, creating tremolo effects. Modulating with an
envelope can produce attack and decay effects.
The "Amp Env" DCA that follows the filter has no controls other than those for
Envelope 4. It is always controlled by this envelope.
3.1g The Filter
A lowpass filter varies a signal's harmonic content by providing progressively greater
degrees of attenuation above a specified cutoff frequency. Higher cutoff frequencies
give a brighter sound; lower cutoff frequencies give a bassier sound since fewer har-
monics are present.
Another filter parameter is resonance. This increases the amount of gain at the cutoff
frequency, which produces a sharper, more resonant sound at high resonance set-
tings. The following figure correlates the cutoff frequency and resonance parameters.
