- The Deep Bass Nine is a very specific
monophonic synthesizer. Unlike normal synthesiz-
ers the controls have been limite to produce a large range of bass-specific sounds. All the
controls are either rotary switches or rotary potentiometers. The main functions are:
1
Env Trigger
Envelope trigger. This LED will light when the DB9’s envelope is triggered
-
either through MIDI with a note on or using an analogue gate signal.
2
Waveform
Waveform selection. This can be sawtooth or square waveforms.
3
Tuning
Fine Tuning. Fine tuning can be adjusted using this control. The Deep Bass
Nine
responds to MIDI notes and "blippy", high-pitched sounds can be obtained
by
playing a higher octave on your keyboard or sequencer.
4
Cut Off Freq.
Filter Cut Off Frequency. This adjusts the cut off frequency of the filter.
This can
also be controlled from MIDI using the modulation controller.
5
Resonance

no reso-
nance - to the classic acid resonance sound.
6

the
envelope.
7
