Studio Bass keyswitch mapping in Logic Pro for Mac

This section outlines the default keyswitch mapping used in of the Studio Bass instruments.

When you load a Studio Bass patch from the Library, you can use a keyswitch map in the Smart Controls to switch between articulations while performing or recording. This lets you add legato or slides, for example, to a bass line in real time. See Manage software instrument articulations in Logic Pro for Mac.

The table shows the default keyswitch mapping, starting from C-1 (MIDI note number 12). You can, of course, transpose the octave of notes used as keyswitches.

Note: Some articulation IDs differ for the American Upright. In such cases, use the second number in the Articulation ID field.

Key	MIDI Note #	Articulation ID	Finger	Pick	Slap	American Upright
C-1	12	1	All (Auto)	All (Auto)	All (Auto)	All (Auto)
C#-1	13	2	Index/Middle (Auto)	Down/Up (Auto)	Slap/Pop (Auto)	Standard
D-1	14	44/52	Index Only	Down Only	Slap Only	Pickup Note
Eb-1	15	3	Legato (HammerOn/ PullOff)	Legato (HammerOn/ PullOff)	Legato (HammerOn/ PullOff)	Legato (HammerOn/ PullOff)
E-1	16	45/57	Middle Only	Up Only	Pop Only	Slap
F-1	17	4	Dead Note	Dead Note	Dead Note	Dead Note
F#-1	18	6	Dead Note Harmonic	Dead Note Harmonic	Dead Note Harmonic	Dead Note Harmonic
G-1	19	5	Harmonic	Harmonic	Harmonic	Harmonic
G#-1	20	56/58	Pickup Hit Single	Pickup Hit Single	Pickup Hit Single	Left Hand Pat
A-1	21	12	Slide by Velocity	Slide by Velocity	Slide by Velocity	Slide by Velocity
Bb-1	22	57/59	Pickup Hit All	Pickup Hit All	Pickup Hit All	Body Tap
B-1	23	37	Slide In +2	Slide In +2	Slide In +2 Pop	Slide In +2
