Build 3561 now includes a new binding source “Engine - String Expression” which lets you setup a string expression using Cantabile’s built in variables and send the resulting string out as a sysex.

hey @brad, when will this binding fire? Every time the string expression changes? What about song / rack load time, even if the expression hasn’t changed between songs?
