Performance problem when using CAPS LOCK piano input
I'm very new to Logic and am running into a performance problem when using the CAPS LOCK-piano-keyboard for input of an instrument: when I'm not recording everything is fine and the program instantly responds on my keystrokes, but as soon as I go into record-mode there is sometimes a delay in the response-time (so I press a key and it takes up to half a second longer before the note is actually played).
Is there anything to do about this to improve performance (for example turning of certain features of the application), or should I never use the CAPS LOCK keyboard anyway and go straight for an external MIDI-keyboard?
Thanks and regards,
