140 Chapter 20 GarageBand Instruments
The interface of GarageBand Instruments consists of a simple silver panel that contains
a number of parameter sliders and associated value fields. As an example, here is the
Digital Stepper instrument:
Many of these parameters are macro parameters, which address specific, useful
parameters in the EXSP24, ES1 (or other equivalent Logic instrument) instance
simultanously.
This has two main benefits:
• as the GarageBand plug-in are smaller, they load faster than the equivalent software
instrument and use less processing power
• limitation to a few, but powerful parameters makes use of the instruments very easy.
Play around with the parameters to see how easy it is to get spectacular sounds!
The Macro parameter sliders available to each GarageBand Instrument are different.
This is because the Logic Instrument’s parameters they address may be different or
because there’s no need to include an organ’s Drawbars parameter on a GarageBand
Piano Instrument, for example—at least not unless you’ve been getting creative with
your Steinway in the garden shed!
