I am attempting some projects which require an envelope to run as fast or faster than an Iterator. That is, the envelope must output numbers as fast as the Iterator in order to get "pairs" of data such as: Iterator output (1) --> Envelope output (0.9) Iterator output (2) --> Envelope output (0.89) Iterator output (3) --> Envelope output (0.88) etc. So basically, I need the envelope data to be interspersed with the Iterator's. In practice, the core envelopes based off the core library toolkit are far too slow. By the time they start putting any data out at all, the iterator has completely finished running an entire iteration. Here is a sample project demonstrating this (also attached). The iterator is in green and the envelope data is in red. The first envelope data is entry #101: The iterator is running at 1000 iterations per second. I am not sure how to set the envelope output speed. This core envelope has a section titled "Speed" as follows: I am not sure if there's something in there I can change to help this envelope output at the necessary speed. How might I accomplish this? Thanks.
