Assigning CC's

To use ASSIGN to program CC devices:-

  1. Set [MODE] to 'MONO 1'
  2. Press and hold the [ASSIGN] button for approximately 2 seconds, the MIDI light will come on solid for a moment and then the LED for [CC 1] will come on indicating it is ready to receive a MIDI message
  3. Release the [ASSIGN] button, the [MIDI] LED will pulse every couple of seconds to indicate it is waiting
  4. Send a MIDI CC command from your controller for the respective device
  5. the MIDI light will light solid for a moment, and then flash twice
  6. the LED for [CC 2] will now come on and will then wait for the second MIDI CC (CC2) to be assigned
  7. steps (4) to (6) will repeat for the remaining [CC x].

If you don’t send anything for a while, or you complete programming of all 4 [CC x], the [MIDI] LED unit will flash 5 times and then come ON steady for a second before exiting the [ASSIGN] mode and returning to normal operational mode.

You have 4 assignable MIDI CCs, by default they are as follows:-

  • CC1 = 74 (cut-off)

  • CC2 = 7 (volume)

  • CC3 = 5 (portamento)

  • CC4 = 2 (breath controller).

PANIC Mode

Should, for any reason, the ED107 become confused and 1 or more GATES become stuck ON, then simply change the [MODE] to a different setting and then return. This will also clear the PolyDAC Cyclic Algorithm allowing the ED107 to start from fresh.

MONO/POLY MODEs

POLY Mode

The current firmware for the ED107 uses a Regular Cyclic Mode for polyphonic operation.

In this mode, incoming MIDI notes are assigned to the next free voice (even if it is the same note played repeatedly).

There are 2 options available in POLY Mode:-

  1. 'IGNORE' - If all voices are assigned (4 notes being played together) then any new notes willbe ignored
  2. 'STEAL' - in this mode the ED107 will 'steal' the first slot originally assigned and replace that note witht he new note.

MONO 1 Mode

All 4 voices are 'locked together' and will respond to the same MIDI NOTE and MIDI Channel

MONO 2 Mode

Each voice is assigned to a different MIDI Channel. Voice 1 is assigned to the address selected with the [MIDI ADDRESS] switch. Voice 2 will be assigned to the next MIDI Channel ([MIDI ADDRESS] + 1), Voice 3 to the next MIDI Channel ([MIDI ADDRESS] + 2) and Voice 4 to the next MIDI Channel ([MIDI ADDRESS] + 3).

This mode allows for up to 4 seperate devices to be connected to the ED107, each with a different signal path through your system.
