Strange Yet Interesting Javascript Patch

bytezen's picture

Enclosed is a macro patch from the Travelator composition in the QC library.

If you look at the code window it seems to be using a type of Javascript format that I don't have access to with the standard QC 4.5 javascript patch. Namely, there is no call to function main.

What I find clever about this is that it enables you to access the last value on the output ports, in this case the previous patch time.

As a learning exercise, I am trying to replicate the same functionality with the standard Javascript patch but no dice so far. In particular the output ports are undefined and inaccessible.

Any thoughts?

A solution:

I am still curious about the "other" style of Javascript patch, but this inelegant solution seems to give the same result. I am using 2 Sample & Hold Patches feed back into the JS patch.

It's an example of the old style Javascript patch. Nothing unusual.
