Aftertouch is just what it sounds like. After a note has been articulated, you can apply
more pressure to a key as you hold it and Aftertouch will output a higher value. In turn, less
pressure outputs a lower value. Unlike Key Tracking and Velocity, Aftertouch isn’t attached
to anything by default. However, some creative uses could include:
A vibrato eect
1. Attach an LFO to Fine Tune on each active sample.
2. While holding a note, adjust the settings of the LFO and its eective range on the
Fine Tune parameters.
3. Attach Aftertouch to the LFO’s Depth and set the Depth knob to its lowest amount.
4. Play a note and apply pressure as you hold it.
5. Adjust the eective range of Aftertouch to set the maximum amount of vibrato you
would want.
6. When playing, applying more pressure will add vibrato.
A sweeping bandpass filter eect
1. Turn on the Master Filter.
2. Engage the Bandpass>RezBP filter.
3. Find your desired cuto frequency lower limit and resonance.
4. Assign Aftertouch to Filter Cuto.
5. Play a note and apply pressure as you hold it.
6. Adjust the eective range of Aftertouch to change the frequency upper limit.
7. When holding notes, applying more pressure will raise the bandpass frequency.
Iris 2 responds to both Channel Pressure and Polyphonic Pressure messages.
Note: Not all MIDI keyboards and controllers support Aftertouch.
