ENSONIQ SQ-R User Manual

,SQ-R Musician's Manual Section 2 - System Control
In MONO mode (A or B) the base channel minus one becomes the MIDI channel
for global controllers (pitch bend, pressure, etc.). For example, if the base
channel is channel 3, any controllers received on channel 2 will be interpreted as
global controllers and will affect all voices being played. If the base channel is
channel 1, channel 16 becomes the channel for global controllers. Each track will
also respond independently to controllers sent on its own channel. For example,
each guitar string on a MIDI guitar can send independent pitch bend, while the
"whammy bar" controller could be sent on the global channel to affect all voices.
Program Changes received on this global controller channel will select different
presets (see Section 3 — Presets for more details).
MIDI Loop/XCtrl
System Bank
MIDI Loop
This determines whether the SQ-R will treat incoming MIDI information as
standard MIDI data or data that is "looped" from the SQ-R's MIDI Out.
Any time you can follow the MIDI path from the SQ-R's MIDI Out and trace it
back into the SQ-R's MIDI In, you have created a MIDI Loop. When the SQ-R
is used in this fashion, it is possible for MIDI volume commands created by the
CVP-1 (Control Voltage Pedal) that go out of the SQ-R to re-enter the SQ-R
through its MIDI In jack and cause it to behave irregularly (for example, MIDI
Volume can have the effect of "looping" and causing the track volume to drop to
zero). The MIDI Loop parameter will allow you to use the SQ-R in these
situations without running into MIDI difficulties.
^ • OFF — The SQ-R receives incoming MIDI information in a normal fashion.
This is the default setting.
• ON — The SQ-R filters incoming data, ignoring volume commands that would
cause difficulty.
Set this parameter to "ON" whenever using the SQ-R in a MIDI Loop.
XCtrl - External Controller
Use XCtrl to assign external MIDI controllers to affect the SQ-R.
Range: 01 to 95
Most controllers on a synthesizer — mod wheel or breath controller for example
— have a MIDI controller number which can be assigned to this parameter.
Doing so will make a panicular external controller available as a modulator to any
of your sounds.
One of the modulation sources that can be selected in the programming section is
XCTRL. The value of the "XCtrl" parameter is a MIDI controller number,
ranging from 01 to 95. When the SQ-R receives MIDI Controller messages
corresponding to this controller number, they will be routed to all parameters
which have been programmed with XCTRL as a modulation source. Suppose,
for example, you are playing the SQ-R from a keyboard with a breath controller.
You can set up a program on the SQ-R in which the filter cutoff frequency is
modulated by XCTRL. If you then set "XCtrl=02," the breath controller will
now be able to modulate the filter, or whatever else has its modulation source set
to XCTRL, in the sound you have created.
