You could put your envelope into a table and run a spline on the table
for the duration of the note. That would give you future values,
interpolated at either arate or krate.

There is a way, you could run an envelope in a loop inside the instrument and read its values into an array or table. You can control it
with as much a read-ahead as you’d like.

One example is when using some of the linseg/expseg opcodes, and incorrectly assume that the last value will be held thus having an envelope (and hence amp) that may be continuously increasing as time passes. If there was a way of haveing a graph plotting future values of the envelope, such thing would be easily spotted.
