Originally, keyswitched instruments were designed to be playable in real time - in other words, someone recording a GPO violin part could easily and instantly switch from arco to pizz by pressing a key on his MIDI keyboard - called a 'keyswitch' - that triggers pizzicato playing.įinale users quickly discovered that GPO’s keyswitches were also useful for Finale playback, not just live playing. To put it simply, a keyswitch is a MIDI note that triggers a different playing technique for a Garritan instrument - for instance, pizzicato on a violin, or harmonics on a harp. However, if you are exploring Garritan Instruments for Finale or another Garritan instrument library for the first time, you may well be wondering what a 'keyswitch' is, and what it has to do with Garritan instrument playback. If you are an experienced Garritan instrument user, you are probably already familiar with the concept of keyswitches.
