72 Audio and MIDI Settings
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.
8.2 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 MIDI Setup button located in the lower right corner of the Settings view 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
Chromaphone 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 section of the Settings view which is
opened by clicking on the Settings tab 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
Chromaphone 3 .
8.2.3 Creating MIDI Control Assignments
Every control on the Chromaphone 3 interface can be manipulated by an external MIDI controller
through MIDI control change assignments or MIDI links.
In order to create a MIDI control assignment:
• On the Chromaphone 3 interface, right-click/Control-click on a control (knob, button) and
select the Learn MIDI Assignment command.
