3.7. Advanced voice parameters

Clicking the "carat" button above the Acid V logo on the upper right side opens up a slide-out
drawer of "under the hood" parameters that give you control over the sound that no original
303 owner could dream of — unless perhaps they were a circuit-bender and handy with a
soldering iron. Left to right, these are:

3.7.1. Bass Boost

As its name implies, this boosts the bass range of the oscillator. You can combine this with
the Sub-Oscillator [p.19]
3.7.2. PW
This stands for pulse width, and when the square
width of the waveform as on many popular analog synths. This creates a definite change in
harmonic content and tone, but one that's subtler than sweeping a lowpass filter.

3.7.3. Accent Attack

On an original 303, you could not adjust the attack time of, well, much of anything. Here,
Acid V allows you to vary the attack time of the filter envelope of notes that have accents.

3.7.4. Cutoff Range

This knob adjusts the range of the main
primary Cutoff knob's minimum and maximum frequencies, for subtler or more dramatic
filter sweeps when you modulate the knob.

3.7.5. Pitch Tracking

Analog oscillators didn't turn input voltage into musical pitch with perfect accuracy. This
setting introduces subtle variations in what pitch the oscillator plays in response to a given
MIDI note. It's bipolar, and even at its extreme ends, this is not enough to create an "out of
tune" sound — it just adds a touch more analog realism.

3.7.6. Noise Gain

Part of the 303's character was that it was not a perfectly clean sounding bass machine, so
Acid V offers a setting to emulate noisy analog IC chips. Again, this is nothing as obvious as
the white noise sources found on many analog synthesizers.

3.7.7. Clipper

All 303s clip with the accent and master output knobs set at maximum. This allows you to
more easily clip the output stage of Acid V if a dirty sound is desired. It's a separate feature
from the other distortion [p.20]
