Controller Usage.13 - Peavey Spectrum Bass II Operation Manual

Chapter 4
Basic Operation
The Bass n responds to this controller and can be used in the Poly and Multi modes to switch to legato playing style.
So, say for instance you are playing in Poly mode, and you send the Bass n a Legato footswitch message. The Bass
H will now behave as though you had selected the Poly-Legato mode with the Mode Select button (although the
LED status will still indicate just Poly). Sending a Legato footswitch message below threshold will bring you back
into normal playing. This is much more versatile and expressive than a straight Legato mode allows for.
Now, the same sort of playing styles are possible in Multi mode. Advancing the Mode Select button until both the
Multi and Legato LEDs are on will yield a MIDI Multi mode (2-6 channels, each capable of a distinct preset) but with
each channel playing in legato fashion. If you happen to be in straight Multi mode and you send the Bass II a Legato
footswitch message above the threshold value, that channel will then switch to a legato playing style. This allows
for a mixture of channels playing legato and normal, with the ability to switch back and forth on any of the six channels
in real time.
The Multi preset selections roll with the MIDI channel selection. Let's take a second to explain this: If the MIDI channel
currently selected is 1, then the Bass n will respond multi-timbrally on channels 1-6 (if the number of channels is
set to 6—the maximum). A channel will play whichever preset was selected as a result of a program change message.
The Bass II is initialized at the factory to play presets 1-6. Now, changing the MIDI channel to channel 2, for instance,
causes Multi response to shift to channels 2-7; BUT, the preset selections remain the same. So, assuming the factory-
preset described above, if the MIDI channel is set to 2, channel 2 will play preset 1, channel 3 will play preset 2,
and so on. This a convenient way to accommodate altering your MIDI setup without having to change presets on
each channel.
The last presets sent to each channel are saved at power down and are available immediately at power up. Also,
the current MIDI mode is saved at power down.
CONTROLLER USAGE
The Bass II responds to several MIDI controller messages, adding a variety of expression not normally achieved -with
a sample playback device.
If your controller lacks the ability to transmit some of these messages, check out the Peavey PC 1600, which can
transmit any controller on sixteen separate sliders, as well as perform real time MIDI mixdown and Sysex control.
In addition to the usual mod wheel, aftertouch, and sustain messages, the Bass n responds to the following controllers:
Volume Controller (#7)
This can be used to control the volume via MIDI, either for overall level control as in Poly mode, or to mix
the levels of the six channels comprising the Multi.
«•* Pan Controller (#10)
This can be used to control the stereo placement of presets as follows:
Values 0-63 will result in placement from hard left to just left of center.
Values 64-127 will result in placement from center to hard right.
This can be used for a set and forget fixed value stereo placement, or in a real time pan sweep.
«•* Legato Footswitch Controller (#68)
This controller is used to switch the playing style between normal and legato as follows:
Values 0-63 will result in normal playing style.
