Keyboards · Arturia
GarageBand plays the keys, but ignores most of the 7 knobs and 10 buttons on the Arturia KeyStep 37. KnobLink connects them: it recognises the KeyStep 37 the moment you plug it in.
GarageBand plays the KeyStep 37's keys and pads, but ignores most of its knobs and faders. KnobLink connects those too: knobs move the instrument's Smart Controls, faders set track volume, transport buttons work.
No. KnobLink recognises the Arturia KeyStep 37 by name when you plug it in and knows its factory settings. If you changed its settings, KnobLink asks you to move the changed controls once.
KnobLink is made for GarageBand. Logic Pro has its own controller assignments.
