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.

MIDI Configuration
8.2.1
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-3
interface and then
click on the checkbox corresponding to any of the inputs you wish to use.
8.2.2
MIDI Channel Volume and Expression Controller
The MIDI channel volume and expression controller (MIDI CC number 7 and 11 respectively)
messages received by
Ultra Analog VA-3
can be used to control gain parameters, and therefore
the output volume, just before the multi-effects processor of each layer and after the global multi-
effects processor. These controllers are enabled in the
MIDI Control
section of the
Settings
window
which is opened by clicking on the
Settings
button located in the right of the utility section at the
top of the interface.
The expression controller is set by default to control the gain parameter located before the
multi-effects processor of each layer. This could be used, for example, to control the output volume
of the synthesizer, but without loosing the tail signal from a reverb. In order to enable this controller,
click on the
Pre-Effects Output Gain
option.
The channel volume controller is set by default to control the gain parameter located after the
global multi-effects processor. In order to enable this controller, click on the
Post-Effects Output
Gain
option.
Both the Pre and Post-effects gains can be assigned to other controllers. In order to change
the assignment, use the drop-down menu corresponding to these gains to choose another MIDI
continuous controller. Alternatively one can click on one of the
Learn
buttons which will link the
corresponding gain parameter to the controller sending the next MIDI CC message received by
Ultra Analog VA-3
.
8.2.3
Creating MIDI Control Assignments
Every control on the
Ultra Analog VA-3
interface can be manipulated by an external MIDI con-
troller through MIDI control change assignments or MIDI links.
In order to create a MIDI control assignment:
•
On the
Ultra Analog VA-3
interface, right-click/Control-click on a control (knob, button) and
select the
Learn MIDI Assignment
command.
