Sculpture MIDI controllers in Logic Pro for iPad
Parameters at the bottom of the Sculpture interface let you define MIDI controllers—for vibrato depth control or Morph Pad movements, for example. You can use any MIDI controller shown in the menus for these control sources.
These parameters are saved with each setting. They are updated only if the default setting that is loaded on instantiating the plug-in is used, or if the setting was saved with a project. This approach helps you to adapt all MIDI controllers to the keyboard without having to edit and save each setting separately.
MIDI controller parameters
Vibrato Ctrl pop-up menu: Choose the MIDI controller used for vibrato depth control.
Ctrl A/B Assign pop-up menus: Choose two controllers that can be used for side chain modulations or as via modulation sources, as set in the CtrlA and CtrlB modulation routing panes.
EnvCtrl 1/2 Assign pop-up menus: Choose controller assignments for the two control envelopes, which can be used as a modulation signal or an offset. Offsets occur in cases where the control envelope is set to Ctrl only or Ctrl+Env modes. These assignment pop-up menus also define the source for recording controller movements.
Morph X/Y Assign pop-up menus: Choose controller assignments for the x and y coordinates of the Morph Pad. After they are assigned, the controller can be used to manually move the morph point, program single Morph Envelope points, shift the entire Morph Envelope, and serve as a source for recording morph movements.
Ctrl Ass(ignment) handling menu: Choose either the default MIDI controller assignments or controller assignments loaded from the setting. If you choose Use Default, assignments remain unchanged. If you choose Load From Setting, you use the controller assignments you saved with the setting. (The default assignments are taken from the #default.pst setting, if it exists, which is loaded when Sculpture is inserted into an instrument channel strip.)
MIDI Mono Mode (MPE) parameters
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, Vibrato Depth Ctrl, and Ctrl A and Ctrl B assignment messages. Controllers and MIDI messages sent on the base channel affect all voices.
Pitch Bend Ran(ge) knob and field: Set a value from 0 to 96.
The chosen pitch bend range affects individual note pitch bend 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.
In certain situations, such as when sliding over a wider range in Mono Mode or applying pitch bend upwards after already dynamically modulating string stiffness to higher values, the resulting pitch may not precisely track the incoming pitch bend beyond a specific threshold. This behavior is intentional, aimed at maintaining model stability while still permitting extreme adjustments of model parameters for innovative sound design purposes. Unlike the Mono Mode PB Range, the standard Bend Range Up is actually used to determine an appropriate safety margin so that notes can still be precisely pitched up by the corresponding amount. As a result, the standard Bend Range Up setting can be used to ensure a specific upward bend range even when operating in MIDI Mono Mode.
Learn a MIDI controller assignment in Sculpture
In Logic Pro, open a controller assignment pop-up menu, and choose the -Learn- item.
Move the controller on your MIDI keyboard or MIDI controller.
Note: If no suitable MIDI message is received within 20 seconds, the selected control reverts to the previous value/assignment.
