Thinning Out Unneeded Data (Data Thin); Creating A Quantized Pattern (Edit Quantize) - Roland Groovebox MC-307 Reference Manual

Chapter 5 Creating Your Own Patterns and
Thinning Out Unneeded Data
(Data Thin)
Since messages such as pitch bend or control change use
continuously changing values, they can occupy an
unexpectedly large amount of memory. The Data Thin
operation lets you thin out such data in a way that will not
affect the audible result, yet will reduce the amount of data.
This allows you to use the memory of the MC-307 more
efficiently.
Procedure
Select the pattern for which Data Thin is to be executed.
1. Press the [PTN] button.
2. Using the [VALUE] dial or the [INC/DEC] buttons,
select the pattern for which Data Thin is to be executed.
Invoke the screen for executing Data Thin.
3. Press the [F3 (EDIT)] button.
4. Press the [F2 (TRACK EDIT)] button.
The screen for selecting Pattern Edit appears.
5. Press the [CURSOR (right)] button to invoke the screen
displaying "DATA THIN."
6. Press the [F1 (THIN)] button.
The screen for editing Data Thin appears.
7. Select the part to be edited using the relevant PART
button, [R], [1] to [7] or [RHYTHM PART VIEW].
* By pressing the [RHYTHM PART VIEW] button you can
specify the MUTE CTRL PART.
8. Move the cursor to "VALUE" by pressing the [CURSOR]
buttons, and then select the amount of Data thin using
the [VALUE] dial or the [INC/DEC] buttons.
9. Move the cursor to "STATUS" by pressing the
[CURSOR] buttons, and then select the kind of data
using the [VALUE] dial or the [INC/DEC] buttons.
Now, execute Data Thin.
10. Press the [F4 (OK)] button.
A screen asking you whether or not you want to execute
Data Thin appears.
11. Press the [F4 (EXEC)] button.
Data Thin is executed and, upon completion, the normal
display reappears.

Creating a Quantized Pattern
(Edit Quantize)
You can modify the musical data of a pattern according to
the Play Quantize settings.
Normally, Play Quantize does not affect the contents of the
musical data, but only modifies the timing at which the
pattern is played back. Executing Edit Quantize allows you
to create data to which Play Quantize is applied.
Procedure
First select a pattern, and use Play Quantize (p. 34) to select
GRID, SHUFFLE, or GROOVE. (If one of these is not
selected, the display will indicate "NO QTZ SELECTED," and
it will not be possible to carry out the procedure.) The
following Edit Quantize operation will be executed with this
setting.
1. Press the [PTN] button.
2. Using the [VALUE] dial or the [INC/DEC] buttons,
select the pattern for which Edit Quantize is to be
executed.
Invoke the screen for executing Edit Quantize.
3. Press the [F3 (EDIT)] button.
4. Press the [F2 (TRACK EDIT)] button.
The screen for selecting Pattern Edit appears.
5. Press the [CURSOR (right)] button to invoke the screen
displaying "QUANTIZE."
6. Press the [F2 (QTZ)] button.
The screen for editing Edit Quantize appears.
7. Select the part to be edited using the relevant PART
button, [R], [1] to [7].
Now, execute Edit Quantize.
8. Press the [F4 (OK)] button.
A screen asking you whether or not you want to execute
Edit Quantize appears.
