4.1 MIDI CHANNEL SELECTION
The D4 can receive and transmit MIDI data in Omni mode (receives data appearing
on any of the 16 MIDI channels, transmits data over channel 1) or Poly mode
(transmits and receives over any one of the 16 MIDI channels).
Use Omni when playing the D4 from an external MIDI controller (MIDI drum pads,
MIDI keyboard, etc.) since it’s not necessary to match channels. When several
instruments are being driven by MIDI (e.g., when a sequencer sends out data over
several channels to different instruments), use Poly mode so that the D4 tunes in to
only the channel containing drum data.
1. The top line of the second page shows the channel status. Example:
CHANNEL: OMNI
THRU: OFF
2. Make sure the cursor is set under the channel status.
3. Turn the Data wheel to select Omni or one of the 16 channels (selecting a single
channel automatically puts the D4 in Poly mode).
4.2 MIDI THRU/OUT SELECTION
When on, this function passes data appearing at the MIDI In to the MIDI Out/Thru
jack as well as to the D4’s internal circuitry. This input data is merged with any data
being generated by the D4. Example: If the D4 is being used for trigger-to-MIDI
conversion and Thru is on, the notes generated by the triggers will be merged with
the data appearing at the MIDI In jack.
When off, the MIDI Out/Thru jack serves as a MIDI Out only from the D4. Input data
present at the D4’s MIDI In is not passed through.
1. The bottom line of the second page shows the Thru status. Example:
CHANNEL: OMNI
THRU: OFF
2. Place the cursor under the Thru status.
3. Turn the Data wheel to select Off (Out/Thru acts as a MIDI Out jack) or On
(Out/Thru acts as a MIDI Thru jack).
