Applying Cyclic Changes To The Sound (Lfo 1/2) - Roland Groovebox MC-307 Reference Manual

keyboard pressed is used to control TIME 1, while the speed
at which the key is released is used to control TIME 4.
- VELO TIME 1
Range: -100– +100
With positive (+) settings, TIME1 will become faster as
you play the keyboard more strongly. With negative (-)
settings, TIME1 will become slower as you play the
keyboard more strongly.
- VELO TIME 4 (Amplifier Envelope Velocity TIME 4
Sensitivity)
Range: -100– +100
With positive (+) settings, releasing the keyboard more
quickly will cause TIME4 to be faster. With negative (-)
settings, releasing the keyboard more quickly will cause
TIME4 to be slower.
A-ENV: TIME KEY FOLLOW
This parameter specifies how the amplifier envelope times
(TIME2/3/4) will be affected by the keyboard pad location.
Relative to the envelope at the C4 note, higher settings of this
parameter will cause the times to change more greatly.
With positive (+) settings, times will become shorter as you
play higher notes. With negative (-) settings, times will
become longer as you play higher notes.
Range: -100– +100
In the following "A-ENV TIME 1-4" and "A-ENV LEVEL
1-3" screens, the TIME 1-4 and LEVEL 1-3 are indicated for
one tone, rather than for Tones 1, 2, 3, and 4. For example, if
before going to this screen the cursor is placed at TONE 2,
then the TIME 1-4 for TONE 2 is indicated.
A-ENV: TIME 1–4
Specifies the time until the next level point is reached. You
can make settings for the four parameters TIME 1–4.
Higher settings will lengthen the time until the next level
point is reached.
Range: 0–127

A-ENV: LEVEL 1–3
Specifies the volume at each point. You can set the three
points Level1–3.Higher settings will also raise the volume.
Range: 0–127
* For details on how TIME 1–4 and LEVEL1–4 of the envelope
correspond with the assignable knob parameters A, D, S, R,
refer to p. 104.
Applying Cyclic Changes to the
Sound (LFO 1/2)
The LFO (Low Frequency Oscillator) provides cyclic
oscillations to sounds. The MC-307 is equipped with two
oscillators, LFO 1 and LFO 2, each of which can be used to
make cyclic changes to the pitch, cutoff frequency and
volume level for each tone, enabling effects like vibrato, wow
and tremolo to be added. As both LFO 1 and LFO 2 have
identical parameters, the descriptions in this apply to both.

(LFO)] button.
5. To edit parameters in the "LFO1:", press [F1 (LFO1)]
button. To edit parameters in the "LFO2:", press [F2
(LFO2)] button.
One of the editing screens appears.
6. Press the [F3 (
)]/[F4 (
parameter to be edited.
7. Press the [CURSOR (right/left)] buttons to move the
cursor below the tone number (T-1 to T-4) for which you
want to define the parameter.
8. Specify a value using the [VALUE] dial or the [INC/
DEC] buttons.
