MIDI Implementation

Tetra receives MIDI data according to the mode controls under G

LOBAL

. In

addition, there is interaction between some of the program parameters that
determine the overall response of Tetra to MIDI data. Note that the following
applies to using both the MIDI jacks and USB.

Following are the Global parameters that affect response to MIDI:

MIDI Channel: ALL, 1…16 —

Selects the MIDI channel to send and receive

data, 1 to 16. All receives on any channel.

MIDI Parameter Send:
NRPN, CC, Off —

Changes to the values of Tetra’s front

panel controls are transmitted via MIDI as Non-registered Parameter Number
(NRPN) controllers or as Continuous Controllers (CC). Transmission of
parameters can also be turned off.

MIDI Parameter Receive: All, NRPN, CC, Off —

Sets the method by which

Tetra receives parameter changes via MIDI. As with transmission, NRPNs are
the preferred method, though some controllers may only be able to send CCs.

MIDI Control: Off, On —

When On, the synth will respond to MIDI controllers,

including Pitch Wheel, Mod Wheel, Pedal, Breath, Volume, and Expression.

MIDI SysEx: Off, On —

When On, the synth will respond to received MIDI

SysEx messages, and will transmit them, when prompted, to the MIDI Out.
