Hi Andy,
This one is pretty easy. Just choose 2 EVs and model each using the
3-column format. For the design you posted EV1 would look like:
20 30 1
130 30 1
180 30 1
etc
The first column is the onset (in sec), the second is the duration and the
final one is the height. Assuming no particular modulation, it's easiest
to just use 1.
The longest period in your design is 110s, I think. So you might want a
HPF of 160s or so.
Cheers,
Joe
