Iris 2 is sample-based software instrument developed by iZotope. Iris 2 is mono-timbral so it will not provide expressive polyphony but will still produce several notes simultaneously and can respond to the Seaboard RISE and GRAND's dimensions of touch.
Step 1 – ROLI Dashboard Settings
Open ROLI Dashboard from your applications/programs folder.
Take a look at the MIDI Settings and Pitch sections in the bottom-right and select:
- Channel Mode: Single
- Channel: 1
- Pitch Bend Range: 24 (Iris 2 has a maximum pitch bend range of 24 semitones)
Step 2 – Set Iris 2 to respond to the Seaboard’s dimensions of touch
Each of the Seaboard's dimensions of touch are transmitted as standard MIDI messages. We want Iris to listen out for those messages, and then do something with them. This is called mapping modulations.
To map modulations in Iris 2, we will drag and drop the controller (the messages that Iris will listen out for) on to the synth parameter that we want to be modulated. Then we click and drag on the newly created modulator to decide how intense that modulation should be.
Strike is transmitted as Velocity. In the animated example below, you will see Strike Modulate the Master Gain. Now, when striking a keywave on the Seaboard, a harder strike will result in a high master gain.
Press is transmitted as aftertouch. In the animated example below, we are using Press to modulate the Master Filter's Cutoff Frequency. Now when sustaining a note on the Seaboard, adjusting the pressure will cause the filter to open and close.
Glide is transmitted as pitch bend. Iris 2 has a maximum pitch bend range of 24 semitones. Earlier on, we used ROLI Dashboard to set the Seaboard’s pitch bend range to +/- 24 semitones. Now we will do the same in Iris 2 so that they match up. (Why does this matter?)
Slide is transmitted as MIDI CC 74 and it can assigned by using the MIDI Assign option and assigning CC74 to a Macro.
- Click on MIDI Assign to turn it on.
- Click on the arrow next to MACRO to expand the Macro module.
- Click on a Macro and perform the Slide gesture on any keywave – you will see MIDI CC 74 mapped into the macro
- Close the Macro module and leave MIDI Assign Mode
- Assign the Macro to the desired parameter.
In this example, we are using Slide to modulate Distortion.
What about Lift?
Lift is transmitted as release velocity. Iris 2 doesn't currently support release velocity as a controller.
