The MIDI Interface Series that Dramatically Expands the Capacity of Your MIDI System

Now You Can Add CV Synthesizers to Your MIDI System

The MPU-101 is unique in that it converts MIDI data into analog signals. When the MPU-101 is connected to a MIDI sending unit, a conventional 1 -volt/octave Cv/gate synthesizer such as the SH-1O1, SH-2, or System-100M can be controlled by MIDI data.
Other voltage-controlled devices can also be controlled. For example, you can automatically synchronize lighting equipment with your performance.
The gate signals can also be used as trigger signals to control a percussion sound source like the Boss PC-2 or HC-2, a sampling unit such as the Boss DSD-2, or a digital delay, for example the Boss DE-200.

The MPU-1O1 can expand your MIDI system's potential just as much as your imagination allows.
The MPU-101 has four output channels, each with pitch control voltage, gate signal, and dynamics control signal outputs. Up to four CV synthesizers can be controlled by MIDI data.
ln addition to the key information, other MIDI data including velocity. bender modulation, after touch, and volume information is converted into analog signals. Complicated MIDI data can completely be converted.
The MID channel can be assigned to one of 1 to 16.

Set-up's

1. Mono Mode: Four CV synthesizers can be controlled by MIDI data transmitted on four different MIDI channels.

2. 2-Voice Mode: MIDI data for up to two notes is converted into CV/gate signals and comes through outputs 1 and 2.
3. 3-Voice Mode: MIDI data for up to three notes is converted into CV/gate signals and comes through outputs 1, 2, and 3.
4. 4-Voice Mode: MIDI data for up to four notes is converted into CV/gate signals and comes through outputs 1, 2, 3, and 4.
5. Special Mode: MIDI data for the highest note, the lowest note. and the latest note is converted and comes through different outputs.

A MIDI Out jack is provided in addition to the MIDI In and Thru jacks. Up to 8 CV synthesizers can be controlled by combining two MPU-101's.
When the connected MIDI sending unit is in the poly mode, three different assign modes are accessible, then the MIDI key information can be
assigned to four outputs in three different ways. An Octave Transpose function simultaneously shifts the pitch control voltage of four CV outputs one octave up or down.
