• GM Drum Kit: Offers lanes that match the note names of the General MIDI (GM) drum
map. This is perfect for creating drum (or other instrument) parts, by penciling or
drawing in note events. This is similar to the use of pattern-based drum machines,
where each beat is manually entered on a grid.
To switch between the MIDI Controls and GM Drum Kit hyper sets
µ Choose a hyper set from the Hyper Set pop-up menu in the Inspector.
This is also how you switch between any hyper sets that you create. Each hyper set can
be named, making it easy to select the one you need.
These event definition and hyper set functions allow you to customize the Hyper Editor,
with only the required MIDI event types being displayed. For example, imagine you have
recorded a synthesizer lead MIDI region. You could create a hyper set that contained
several customized event definition lanes for the note events in the region.
Each note event lane in the example is restricted to the display and control of a single
note pitch. By default, each beam that represents note events can be adjusted in level,
by dragging vertically with the Pointer tool. Within the same hyper set, you could create
two event definition lanes that control the filter cutoff and filter resonance parameters
of the lead synthesizer, allowing you to create or precisely edit filter tweaks.
