/* Midi Monoizer (c)2019 by Andrew Shakinovsky andrew@afrittemple.com
|
||||
I welcome comments or suggestions.
|
||||
Description:
|
||||
Insert this before a VSTi in the chain. It will prevent multiple midi notes from
|
||||
sounding at the same time. When a note is playing and another note is received,
|
||||
a note-off is sent for the first note before(*) the new note is sent. This is akin
|
||||
to typical monosynths when you are holding a key and then press and release another
|
||||
key: the first key plays, then the second, and when you release the second, the first
|
||||
key will play again. A lot of VSTi's behave in this way, but there are some that do
|
||||
not, and that is where this becomes helpful.
|
||||
|
||||
(*) will be sent after the note on depending on the legato slider. If the legato slider
|
||||
is no zero, the note off will be delayed by that many samples to allow the synth to
|
||||
treat it as legato playing
