Changing Other Parameters (Assignable Knobs) - Roland Groovebox MC-307 Reference Manual

Chapter 3 Giving Variation to Pattern
- FILTER: Changes the cutoff frequency of the filter.
- AMP: Changes the amplifier volume level.
LFO Waveform
- TRI (triangle): The sound will be modulated
continuously. This is a frequently-used waveform, and is
suited for effects such as vibrato.
- SIN (sine wave): The sound will be modulated smoothly.
- SAW (sawtooth wave): When the sound reaches the
upper value, it will return to the original position and
begin rising again.
- RND (random): This setting causes the sound to change
unpredictably, and is suitable for creating sound effects.
- S&H (sample & hold): This setting causes the sound to
change unpredictably, and is suitable for creating sound
effects.
- SQR (square wave): The sound will be modulated as if it
were being switched between two positions.
This procedure is equivalent to the [LFO1] operation of the
Patch Edit function. With the Patch Edit function, the two
waveforms shown below can also be selected.
- TRP (trapezoid wave): The sound will be modulated as if
it were being switched between two positions. The curve
at the transitions differs from square wave.
- CHS (chaos): This setting causes the sound to change
unpredictably without regard to frequency, and is
suitable for creating sound effects.
Changing Other Parameters
(Assignable Knobs)
You can assign any parameter you wish to the assignable
knobs. In this case, the settings for Knobs 1-4 are saved as a
single set. This is referred to as a User set, with ten such User
.
sets available for your use
Using the parameters listed on the
panel
On the panel, parameters are listed above the respective
assignable knobs, allowing you to make selection.

Procedure
1. Press the button to the left of the assignable knobs.
Each time you press it, ">" in the figure comes on in
sequence. Thus, you can select from the functions listed
on the display. The available functions are listed in the
column with ">" on.
2. Operate the knobs while playing back sounds.
