245 Instrument, Drum and Effect Racks
4. An incoming MIDI note gets compared to a chain’s key zone. If the MIDI note lies within
the key zone, it is passed to the next zone for comparison; if it does not, then we already
know that the note will not be passed to that chain’s devices.
5. The same comparisons are made for the chain’s velocity and chain select zones. If a note
also lies within both of these zones, then it is passed to the input of the first device in that
chain.
6. The output of all parallel chains is mixed together to produce the MIDI Effect Rack’s final
output. If there happened to be another device following after the Rack in the track’s de-
vice chain, it would now receive the Rack’s output for processing.
18.5.2 Key Zones
The Key Zone Editor.
When the Key button is selected, the Key Zone Editor appears to the right of the Chain List, il-
lustrating how each chain maps to the full MIDI note range (nearly 11 octaves). Chains will only
respond to MIDI notes that lie within their key zone. The zones of individual chains may occupy
any number of keys, allowing for flexible “keyboard split“ setups.
Key zone fade ranges attenuate the velocities of notes entering a chain.
