Alchemy extended parameters in Logic Pro for iPad
Alchemy provides additional parameters that set the overall output quality and change the way Alchemy responds to incoming MIDI note information.
Extended parameters
Quality pop-up menu: Choose the processing resolution on output. This setting remains active when loading other presets or when recalling the project.
MIDI Mono Mode pop-up menu: Choose Off, On (Common Base Channel 1), or On (Common Base Channel 16).
In either mode, each voice receives on a different MIDI channel. Per voice channels support pitchbend, aftertouch, mod wheel, and Performance control assignment messages. Controllers and MIDI messages sent on the base channel affect all voices.
Mono PB Range field: Set a value from 0 to 96.
The chosen pitch bend range affects individual note pitchbend messages received on all but the assigned Common Base Channel. The default is 48 semitones, which is compatible with the GarageBand for iOS keyboard in pitch mode. When using a MIDI guitar, 24 semitones is the preferable setting because most guitar to MIDI converters use this range by default.
