Ocean waves on a pebbles beach, realistic and unpredictable washing while at times some exotic birds sing around you. Tracks 1 and 2 are my samples, 3 and 4 are from default Tempera internal Canvases, tracks 5-8 are empty. Go to settings and change the BPM to 18, we don't want too many notes overlapping. Each emitter has its own midi channel, you may use an external controller but the internal overlay keyboard works perfectly in this setup, all notes are hold. Overlay Keyboard is Right 1/4, as depicted. On the overlay keyboard midi menu, assign the notes of the first (blu) Emitter (Midi ch 1) as indicated in the photo, then change to channel 2 and assign the magenta ones and so on to all channels.

Midi ch1 Blue Emitter
Midi ch2 Magenta Emitter
Midi ch3 Yellow Emitter
Midi ch4 Green Emitter

Notes indicated are of course just that, indications, but this setup gives a good feel of what the Canvas is. Another interesting point here is the use of Modulators and the Grain Pan to bring the Emitters in and out of the scene in ever changing overlapping ways. Careful, volume gets loud at times.

Enjoy!
