MIDI Implementation

The MP-201 offers a wealth of possibilities as a MIDI controller. This section covers the

MIDI conguration, as well as the MIDI Output and Input possibilities of the device.

When using the MP-201 as a MIDI controller, the rst thing that must be done is

congure the MIDI Setup. On the MP-201 you can enable/disable both the DIN and

USB MIDI connections, as well as assign MIDI Merge functions for these connectors.

This is available to the user in two Areas: as Global settings in the Utilities Mode MIDI

Setup menu (page 40), or as Preset-specic settings in the Edit Mode MIDI ALL menu

(page 30). The possibilities for creating MIDI loops exist when connecting to other MIDI

devices or software, so be careful when choosing these settings.

MIDI Continuous Controllers (CCs)

A MIDI CC message can be used to control parameters in other MIDI devices or

software. A MIDI CC message has a Number and Value. The Number indicates the

type of MIDI CC being sent, and the Value is the current level, much like an Analog CV.

There are 128 MIDI CC numbers and each with a value of 0-127 (128 levels). Some

MIDI CC Numbers are standard, such as MIDI CC#7, which controls Volume. Many

manufacturers implement use of MIDI CCs in their own way so be sure to consult the

documentation of the device you wish to control to understand what MIDI CCs are used.

Each of the MP-201’s four Channels can be assigned to send a single MIDI CC on a

user-selectable MIDI Channel, based on that Channel’s settings. A MIDI CC is a MIDI

Channel Message, which means it is assigned to a MIDI Channel. This means that the

MIDI device you are controlling with a CC (from the MP-201) must be assigned to receive

MIDI on the same MIDI Channel that the MP-201 is assigned to send.

The MIDI CC output by that MP-201 Channel will be a MIDI version of the analog

output for that channel, but with only 128 levels. This means that the MIDI CCs sent

by the MP-201 can be Expression, LFOs, or Gate signals.

A MIDI CC received by the MP-201 of the same CC number and on the same MIDI

Channel of a current MP-201 Channel will cause a change in the Analog output. The

changes at the analog output depend on Channel Mode.

If a MP-201 Channel is set to Expression Mode and set for MIDI Channel 1, MIDI

CC#1, then a MIDI stream of CC#1 messages received on MIDI Channel 1 with

values changing from 0 to 127 will cause the MP-201 to output an analog CV changing

from 0 to +5 Volts in Unipolar Mode, or -5 to +5V in Bipolar Mode.
