Dual Mini Sequencer MIDI Expander Operating Instructions
Make sure the MIDI Expander module is connected to the programming headers in the back of your Dual Mini Sequencer
The MIDI out feature of the DMS is disabled by default. If you’ve never used it, you’ll need to enable it:
- Reset or power-cycle the sequencer
- As the sequencer is booting, hold down the B button
- After the boot light show, the LEDs will blink to indicate that the MIDI feature has been enabled
Note on/off events will now be sent out the MIDI port on the main MIDI channel.
Note: When MIDI is enabled, the ACC output will not be enabled (it is used to send MIDI serial data)
Select Main MIDI Channel
The default main MIDI channel (for note on/off events) is 1. To change it, hold down the REST button and use the STEP UP / STEP DOWN buttons to select a channel. The STEP LEDs will indicate the current channel.
Enable/Disable Note On/Off Messages
If you want some of the other MIDI messages the sequencer sends, but not the note on/off messages, you can toggle them by holding the REST button and tapping PROG/RESET. The LED will blink twice when enabled and flicker when disabled.
Enable/Disable Clock Messages
The sequencer can send MIDI clock (24 PPQN), start/continue/stop, and song position pointer (SPP) messages (note: these messages have no channel associated with them). To toggle them, hold the LOOP button and tap PROG/RESET.
Enable/Disable Aux Messages
The sequencer can send the following auxiliary messages:
- ACC on/off (note 36; because the ACC O-UT jack is disabled when MIDI is enabled)
- Step gate (steps 1-16 turn on MIDI notes 48-63)
- Sequence gate (sequences 1-7 turn on MIDI notes 72-78)
- Song gate (songs 1-5 turn on MIDI notes 84-88)
To toggle MIDI aux messages, press and hold ACC and tap the PROG/RESET button.
Select AUX MIDI Channel
To select the MIDI channel for aux messages, hold down the ACC button and use the STEP UP / STEP DOWN buttons to pick a channel. The STEP LEDs will indicate the current channel.
