To add Keyswitches as Expressions

While using Garritan instruments for playback, you can add a keyswitch at any point to change the instrument sound, for example, from arco to Pizzicato. A Keyswitch is simply a regular note outside the range of the instrument that triggers this change. For a list of Keyswitch mappings, see Garritan Finale Edition Instrument Details.

If Human Playback is enabled, text (such as “arco,” “pizz,” etc.) is interpreted and keyswitches are added automatically. If you are not using HP, choose from a list of keyswitch expressions available by default in the Expression Selection dialog box to add these effects.

You can also assign a Keyswitch to an expression manually by defining the expression to send a MIDI Note On message at the pitch of a Keyswitch. By doing this, you can invoke a Keyswitch by simply adding the expression defined accordingly (a “Pizz” text expression would change the playback to a pizzicato sound). Remember, Keyswitches are a feature of GPO, and will not apply to other playback devices.

1. Click the Expression Tool  , and Double-Click the document. The Expression Selection dialog box appears.
2. Click Create. Or, you could also select an existing Expression you would like to define to a Keyswitch and click Edit.
3. Type the desired text. Set the font, size, style, make it hidden, or apply other text attributes.
4. Click the Playback Tab. The playback options appear.
5. From the Type menu, choose Dump. The Playback Data Dump dialog box appears.
6. For Number of Units, type 3. We will be sending 3 pieces of Data.
7. For the top Data box, type 144. This is the message for Note On.
8. For the second Data box, type the MIDI Note number for the Keyswitch. For example, Arco = 0, Pizz = 5 in Finale GPO). For a complete list, see GPO Finale Edition Instrument Details.
9. In the third data box, type 127. Since the note is below the instrument’s range, it will not sound.
10. Click OK, OK, Assign to add the Expression. The performance style will change upon reaching this point during playback.
