Alchemy Transform pad in Logic Pro for Mac
When simple view is active, or if the Perform button is on in the Perform/Arp/Effects section in other views, the performance controls subpage is displayed.
Alchemy presets contain eight snapshots of performance control settings, numbered 1 to 8. By default, snapshot 1 is selected. This is indicated by the framing box.

Transform pad controls
In addition to the parameters outlined, you can Control-click directly on snapshots in the Transform pad to open a shortcut menu with a number of snapshot and other commands. See the tasks in this section for details about use of these commands.
Transform pad: Drag the framing box to different positions to morph between performance snapshots in real time. The performance control knobs update, modulating the associated parameters.
Action menu button: Open a pop-up menu with a number of snapshot-related commands.
Copy Snapshot: Store all performance control settings of the selected snapshot in a buffer.
Paste Snapshot: Paste all performance control settings from the buffer to the selected snapshot.
Copy 1 To All: Copy all performance control settings of snapshot 1 into snapshots 2 to 8.
Clear: Capture the current performance control values and apply them directly to target parameters, preserving the current sound. Following use of the command, all performance control and Transform pad assignments are cleared, all controls are reset to zero, and the knob and pad name fields are wiped.
Randomize Snapshots: Create random performance control values for all snapshots except the currently active snapshot.
Auto Assign All: Automatically assign all performance controls to appropriate parameters in the current preset. This command also generates a random set of snapshots that are derived from the settings in snapshot 1. This is the quickest way to start with the performance controls.
Auto Assign Empty: Automatically assign all unused performance controls to appropriate parameters in the current preset. Existing performance control assignments are not affected, and no snapshot settings are created.
Snapshot Update: Enable to immediately write changes of performance control values to the nearest Transform pad snapshot. This prevents the performance knob from reverting to its previous position when you move a performance knob and then move the Transform pad framing box slightly.
Tip: This parameter is on by default, but you can enable or disable it as preferred and then save the default preset in the plug-in header to recall this behavior in new presets.
Octave pop-up menu: Define an octave range used to switch between Transform pad positions when you play notes within the specified range.
Rate field: Drag vertically or use the arrows to set the speed of movement (interpolation) between snapshots when switching from a MIDI keyboard.
ModWheel pop-up menu: Assign your keyboard modulation wheel to a performance control. This can be any knob, the x- or y-axis of pads, or the envelope controls. Set to None to disable modwheel control of performance controls. A setting of None is remembered between presets. See Alchemy performance control knobs in Logic Pro for Mac, Alchemy XY pads in Logic Pro for Mac, and Alchemy performance control envelopes in Logic Pro for Mac.
Each modwheel target offers an inverted option. This is useful when using a spring-loaded modulation wheel as it stops the target performance control from closing when the modulation wheel is released.
Snap Vol field: Set the intensity of change from one snapshot to the next. In essence, this sets an initial level between snapshots.
All snapshots should be approximately the same volume, with a peak level around –5 dB. You should also be mindful of relative volume levels between snapshots. For example, a soft pad and a distorted lead could both peak at –5 dB, but the lead may seem louder. In this scenario, lower the volume of the lead, rather than increase the pad level, so that relative volume levels seem similar between the pad and lead sounds.
