Two-Voice Pro QuickStart Guide

MIDI

An external MIDI keyboard connected to the TVS-PRO can also be used to transpose sequences. Make sure that the KEYB TRANS 

button is enabled on the TVS-PRO.

An external keyboard connected to the TVS-PRO’s MIDI IN port supports the following TVS-PRO keyboard 

modes:

•  Unison mode with and without Retrigger

•  Split mode with and without Retrigger

•  Two-voice polyphonic mode

SYNCING THE MINI-SEQUENCER WITH A MIDI DEVICE

The TVS-PRO mini-sequencer can be synchronized to and triggered by an external MIDI device. When the 

sequencer is driven by MIDI CLOCK, it responds to MIDI START and MIDI STOP commands from the external 

MIDI device.

To synchronize the mini-sequencer to an external MIDI device:

1.  On the TVS-PRO, press MIDI CLOCK. The mini-sequencer will start when it receives an incoming MIDI 

CLOCK signal. (You do not need to press RUN on the TVS-PRO.)

To multiply the mini-sequencer clock rate by a factor of 2 or 4:

1.  Press SHIFT once, then press CLK.

2.  Select the desired rate with the UP and DOWN switches in the SEQUENCE section. The number shown 

will be +2 for double rate, +4 for quadruple rate and if desired, back to +1 for the default rate.

An external MIDI keyboard connected to the TVS-PRO can also be used to transpose sequences. Make sure that the KEYB TRANS 

button is enabled on the TVS-PRO.

MIDI OUT

MIDI OUT information comes from two sources in the TVS-PRO:

•  The TVS-PRO’s keyboard. 

•  The mini-sequencer. (MIDI OUT information is active whenever the mini-sequencer is playing.)

In order to enable MIDI OUT from the TVS-PRO keyboard, you must turn on RE-TRIGGER
in the Keyboard Control section.
