Play it via MIDI
You don't need to know the instrument, or music. It is tuned so that you cannot play a wrong note: every key falls to the nearest tone that fits what is sounding, near the octave you played. Plug in and play.
- Open the instrument in Google Chrome.
Playing over MIDI needs Web MIDI, and that runs in Chrome. Headphones on, and start soft.
- Connect your keyboard or controller, then click once on the page.
The click starts the sound (browsers wait for a first touch). Any USB MIDI keyboard works.
- Allow MIDI when the browser asks.
A small prompt appears the first time. Say yes.
- Choose your device in the instrument's MIDI in menu.
A dropdown on the page, sometimes under Options or stel in. Pick your keyboard by name.
- Play.
Press any keys. It stays in tune with itself, so wander freely. Lower keys tend to sit deep, higher keys open and lift.
On a ROLI or other MPE controller: pressing harder swells each note, and sliding a key morphs it, per note. There is nothing to switch on, it just responds. On a normal keyboard everything still works; MPE only adds the per-note touch.
