when the V3 is first turned on or the V3's program number is changed. The second function of this push-button is to
activate the remote save function of the V3. All patch parameter and rotating speaker settings are saved to the
current patch number by holding down the DRAWBAR / SAVE button for approximately four seconds. All the
front-panel indicators will light, indicating the save function was performed.
The functions of the rotary controls when the MIDI Drawbar is used with the V3 are as follows:
VOLUME
- a standard MIDI continuous controller volume control.
OVERDRIVE
- controls the V3's overdrive mix parameter.
KEY CLICK
- adjusts the V3 key click (attack) volume parameter. Key click is an electrical noise generated in
tone wheel organs by the mechanical bounce of nine key contacts. It will be necessary to restrike any notes being
held on the keyboard to hear the change made to the sound since key click occurs on the attack of the note.
LEAKAGE
- adjusts the level of the V3's generator leakage. Generator leakage is the sound created by the crosstalk
of the tone-wheels in a B-3. It's a breathy ethereal sound keyed in beneath the main sound.
The functions of the drawbars when the MIDI Drawbar is used with the V3 are as follows:
Drawbar changes can be used to update the main drawbar settings of the V3 or the morph (AUX) drawbar setting of
the V3. Any changes to the drawbars are instantly reflected by the V3 provided the morph control is set to reflect the
drawbar changes (MAIN or AUX) which are sent.
Using the MIDI Drawbar With A Sequencer
The best way to record drawbar changes and other MIDI control changes produce by the MIDI Drawbar is to record
from the THRU output of the V3 (or the next module after the MIDI Drawbar). This will allow note on/off
information as well as control changes to be saved in a MIDI sequence. Its best to press the RE-XMIT button at the
beginning of a sequence in order to save the state of the MIDI Drawbars in the sequence.
To play back a MIDI sequence, connect the MIDI out of the sequencer directly to the V3 (or other sound module). It
is also possible to view the push-button changes as they occur in the sequence by connecting the sequencer's MIDI
output to the MIDI Drawbar input. The MIDI Drawbar is capable of displaying control changes it detects at its
Merge Input which coincide with its push-buttons' control numbers. These changes will light the push-button
indicators accordingly. For example: if control number 68 is detected at the Merge Input it will set the Rotating
Speaker Slow/Fast indicator to reflect this change.
Using the MIDI Drawbar as a Continuous Controller
The MIDI Drawbar to be used as a general purpose MIDI control box and a merger. Fourteen continuous controllers
and nine push-button / foot switch controllers can be merged with a keyboard or sequencer output. Many modern
synthesizers and effect processors can use external continuous controllers to modify parameters in real time. Control
of these parameters in real time has live performance applications, as well as reducing the time it takes to program
sound modules and effect processors. The MIDI Drawbar also makes an excellent controller for MIDI lighting and
mixing applications.
