Analog Modeling Bass; Playing From The Effect Knobs - Roland MV-8800 Owner's Manual

Analog Modeling Bass

Analog Modeling Bass is an algorithm that replicates the operation of an analog synthesizer.
If you control the parameters with the Velocity Pads or externally with MIDI messages, you can get analog
synthesizer sounds with the virtual VCO (Voltage Controlled Oscillator). Furthermore, with sections
corresponding to VCF (Voltage Controlled Filter) and VCA (Voltage Controlled Amplifier), you can also
process external sound input as is. Additionally, a ring modulator is included, and with the output from the
delay and chorus (or flanger), it can be used as a powerful multipurpose filter/effect device.
●
Other than the delay and chorus/flanger, the effect portions of this algorithm cannot be turned off.

By selecting Analog Modeling Bass, you can use the MV-8800's effect section as a monophonic synthesizer.
You can control note-on/off and pitch in several ways.

Playing from the Effect knobs

If you want to use the synthesizer to create a sound effect, rather than playing definite pitches in a scale, you
can use the effect knobs to easily make the synthesizer start or stop producing sound. For example, you can
assign the following parameters to the effect knobs.
C1: Trigger In—Common block (Appendices; p. 54)
C2: Note Number—Common block (Appendices; p. 54)
C3: VCF Cutoff—VCF block (Appendices; p. 57)
VCF Reso—VCF block (Appendices; p. 57)
LFO Rate—LFO block (Appendices; p. 55)
LFO Depth—LFO block (Appendices; p. 55)
etc.
●
Explanation of the Knob Assign, refer to "KNOB ASSIGN popup" (Screen Guide; p. 234).
The synthesizer will begin sounding when you turn C1 to the right, and will stop when you turn it to the left.
Turning C2 will change the pitch. If the Common parameter Portamento (Appendices; p. 54) is on, the pitch
will change smoothly.
While you listen to the song play or a sample loop, turn the knobs to control the sound effect as desired.
