Depending on your machine you should choose, for a given sampling frequency, the smallest
buffer size that allows you to keep real-time for a reasonable number of voices of polyphony.
6.2 MIDI Configuration
6.2.1 Selecting a MIDI Device
The list of available MIDI inputs appears at the bottom of the Audio Setup dialog. Click on the
Audio Setup button located in the lower left corner of the Ultra Analog VA interface and then click
on the checkbox corresponding to any of the inputs you wish to use.
6.2.2 Creating MIDI Links
Every control on the Ultra Analog VA interface can be manipulated by an external MIDI controller
through MIDI control change assignments. In most cases this is much more convenient than using
the mouse, especially if you want to move many controllers at once. For example, you can map the
motion of a knob on the interface to a real knob on a knob box or to the modulation wheel from
your keyboard. As you use the specified MIDI controllers, the controls move on the Ultra Analog
VA interface just as if you had used the mouse.
In order to assign a MIDI link to a controller:
• On the Ultra Analog VA interface, right-click/Control-click on a control (knob, button) and
select the MIDI Learn command.
• Move a knob or slider on your MIDI controller (this can be a keyboard, a knob box, or any
device that sends MIDI). This links the control of Ultra Analog VA to the MIDI controller
you just moved.
To deactivate a MIDI link, simply righ-click/Control-click on the corresponding control on the
Ultra Analog VA interface and select the MIDI Forget command.
6.2.3 Creating a default MIDI Map
It is possible to define a a set of MIDI links, called a MIDI map, that will be loaded automatically
when Ultra Analog VA is launched. Once you have defined a set of MIDI links that you wish to
save, click on MIDI button to open the MIDI configuration window and click on the Save Current
as Default button.
If you make changes to MIDI links after opening the program and wish to revert to the default
MIDI map click on MIDI button to open the MIDI configuration window and click on the Load
Default button.
If you wish to deactivate all the MIDI links at once open the MIDI configuration window and
click on the Clear MIDI Map button.
