Open ROLI Dashboard
- Turn MPE off.
- Select a channel range starting from 1. The range you set will determine the expressive polyphony.
- Set Pitch Bend Range to 24.
Open Ableton Live and create a MIDI track with Operator as the instrument:
- Create a patch in Operator that responds to the Seaboard's dimensions of touch
- When you're happy with the patch, duplicate the MIDI track to match the channel range set in ROLI Dashboard. Example: if channel range is set from 1 - 5 in ROLI Dashboard, duplicate the first MIDI track until there are 5 MIDI tracks total
- On each track set 'MIDI from' to Seaboard
- Directly below 'MIDI from', set the Input channel for each track sequentially from 1 to 5
- Record arm each of the 5 MIDI tracks
The Seaboard utilises multiple channels of MIDI to achieve polyphonic dimensions of touch. Operator is a mono-timbral instrument capable of producing one timbre on one channel of MIDI at a time while. You'll need to create a number of identical instances of Operator to access the multi-timbral nature of the Seaboard and take maximal advantage of the polyphonic dimensions of touch.
Step 1: ROLI Dashboard Settings
Ensure that ROLI Dashboard’s MIDI Settings are set as shown below.
* Larger or smaller channel ranges can be selected. Fewer channels will reduce the number of tracks required in Ableton, but will also reduce the expressive polyphony. More details on selecting the ideal range here. In this example we are using a range of 1 - 5 (which will provide 5 voice expressive polyphony) but you can just as easily use 1 – 10 (which would require more tracks and provide 10-voice expressive polyphony) if you prefer.
We have selected:
- Use MPE: Off
- Channel Range of 1–5
- Press Mode: Channel Pressure
- Pitch Bend Range of 24
Step 2: Create your first MIDI track with Operator
Create ➝ Insert MIDI Track to add a MIDI track to your Set. Under MIDI From, select the Seaboard Ch. 1.
Load Operator into the track. At this stage you might want to set ROLI Dashboard’s Channel Mode to Single so that all of the notes are transmitted on the same channel while you experiment with your patch’s response to the dimensions of touch.
Step 3: Operator Parameters
Adjusting a few settings within Operator will allow it to respond to the Strike, Glide, and Press dimensions of touch - Strike corresponding with 'Velocity', Press with 'Aftertouch', and Glide with 'Pitch Bend Range'.
Set Polyphony and Pitch Bend
- Click on the Global Shell area of Operator
- Set Voices to match the range you set in ROLI Dashboard. In this example, set it to 5.
- Set the Pitch value to 24
Set Velocity and Aftertouch
- Velocity Connection A to Volume - Set Amount A to 100
- Velocity Connection B to Tone - Set Amount B to 100
- Aftertouch Connection A to Volume - Set Amount A to 100
- Aftertouch Connection B to Tone - Set Amount B to 100
Step 3: Duplicate your MIDI track 4 times
Using ⌘ -D (Mac), or ctrl – D (PC), duplicate the first track 4 times and set the channels under MIDI From so that each track receives on a channel from 1–5.
Note: If you have set ROLI Dashboard's Channel Mode to 'Single' to build your patch, you can now set it back to 'Multi'.
Step 4: Play
Arm all 5 tracks with ⌘-click (Mac), or shift-click (PC) and play!
If you change your mind about the patch, go to ROLI Dashboard and set Channel Mode back to Single. Preview the patch on track 1 then you can copy it quickly to the other tracks by duplicating again.
