BeatSync,
V1 - 20 Mar 2005
...BeatSync is for "quantizing" note-on messages, selectable quantize from 1-8 beats.
It is for triggering MIDI Parts/AudioParts/Arp phrases live in EnergyXT in sync
with the song, with the button on the right enabled,
the note-off messages will be filtered out so you don't have to hold the key,
toggling the button off will kill all the held notes.
I usually use a combination of TransMSG send CC123 on host stop to kill the triggers,
and also have keys assigned in XT to kill triggers.
