Set the tempo values in the Tempo Interpreter window
1. In Logic Pro, choose Edit > Tempo > Tempo Interpreter (or use the Open Tempo
Interpreter key command).
2. In the Tempo Interpreter window, adjust any of the following:
• Tap Step: Sets the note value that Logic Pro assigns to manual taps. You achieve the
best results with larger, rather than smaller, values. 1/4 note usually works well.
• Window: Determines the time span (or window) within which tap notes can be
entered (set in ticks, or 1/3840 note). Only taps made within this time window are
used to determine the tempo. Any taps outside it are ignored.
• The narrower the window, the more effectively Logic Pro is able to withstand the
influence (on the tempo) of any taps that fall between the note values—set with
the Tap Step parameter.
• The larger the window, the easier it becomes to create drastic tempo changes.
• If you set the window parameter to 0, the tap window disappears altogether, and
all taps are accepted as tempo-determining information. Logic Pro also comes to
a halt, if taps are not generated.
• Tempo Response: Sets the sensitivity to tempo changes:the larger the value, the
greater the sensitivity. You should set this value to 4, for most situations. If you find
that your tap timing is imprecise, but want Logic Pro to play at a relatively constant
tempo, reduce this value to 2 or so.
• Max. Tempo Change: Use this parameter to set the maximum tempo change possible
per tap (in bpm). To obtain the most regular, or even tempo curve, follow this
rule:set the smallest possible value (in other words, only as large as necessary).
• Tap Count-In: Sets the number of taps used as a count-in. Logic Pro starts following
the tempo on the first tap after the count-in taps.
• Smoothing: Turning on this function smooths out jumps in tempo, resulting from
incoming taps (which could prove useful when using Logic Pro live). You should turn
it off if you want Logic Pro to follow your taps precisely and quickly.
• Tempo Recording: Creates a tempo list that follows your taps, when in record mode.
This option should normally be turned off.
• Pre and Post: Determine which tap signals are displayed:
• Pre: Displays every incoming tap.
• Post: Displays every accepted tap that occurs within the time window (as defined
by the Window parameter), or close to, or on, a tap step.
The Pre/Post tap signals flash yellow if the taps are within the allowed range, and red
if they are out of range.
Note: Only the selected software instrument track, and all external MIDI tracks, can play
when the Tempo Interpreter window is open.
