When selecting one of the realtime blocks, you have the third option of selecting
SEt
. This
acceesses any parameter within the edit buffer, displays its value, and allows you to change
that value. SEt has the following menu items:
PAr
Selects the edit buffer parameter to be edited. Use the edit buffer table (Appendix
C) to look up the offset of the desired parameter. The right-hand bargraph
(output headroom/gain reduction) shows the parameter's current actual edit
buffer value on a linear scale of 0 (no LEDs) to 127 (all LEDs).
oFt
Offset (from zero) to apply to source value.
Press
L
EAVE
E
DIT
to exit this mode.
A.1 Realtime MIDI Example.
Refer to the description of Realtime MIDI Block 1, which can be found in Appendix C. We'll use
modulation source six, the dynamics section log signal level. This control source represents the
logarithm of the signal level presented to the dynamics section. The dynamics section uses it to
drive the compressor, expander, and AGC sidechains. We'll use it to control the filter frequency
of band 2 of the parametric equalizer block.
Begin by accessing band 2 of the equalizer. Set the
L
EVEL
parameter to +15 dB, and the
B
W
parameter to 0.5.
Access realtime edit mode by pressing the
M
IDI
button until the display reads
rEAL
.
Pressing the
M
IDI
button again, the display now reads
bLC
. Select block
0
using the Wheel.
Press the
M
IDI
button again. Use the Edit Buffer parameter table to locate the offset of the
desired parameter. We want parameter
10
.
Press the
M
IDI
button again. The display reads
SrC
. Since we want the log signal level to become
the controller for the filter frequency, select
6
as the modulation source using the Wheel.
Press the
M
IDI
button twice. The display should now read
oFt
. While listening to the 601's
output, adjust the offset value until you hear the equalizer filter begin to work. You can then
use the
SCAL
parameter to alter the range of the effect.
Note
: whenever one of the realtime blocks has been set up and attached to a parameter, trying
to edit that same parameter from the front panel results in the message
rEAL
whenever the
Wheel is turned. This is true only for realtime blocks one and two, and not for the
SEt
function.
Accessing the parameter attached to the realtime block, from the front panel, results in the
display temporarily showing the current value of the parameter. This can be useful in
determining useful limits for a parameter, or to view the results of offset and scale operations.
