They're free, by the way.

I can't can't get Legato Mode to work right in Opus 1 nor any other Horizon Series product (I have all the Horizon Series products which use "legato-mode" except Chamber Strings.)

The release sample keyswitch on "perf-leg" patches also has odd behavior (late triggering of the +RS .wavs.)

Longshot here, but I thought I'd ask. This script would mean people would no longer need the external application, Performance Tool.exe, which would keep all MIDI inside the VST host. The benefit there is the ability for offline rendering, vs. current real-time, 1:1, rendering. And no need for virtual MIDI ports.
