![]() Varispeed provides a way to speed up or slow down the entire project, similar to the original varispeed feature of tape machines. The most practical use for this option is checking how a project might sound at a faster or slower tempo, and for practicing or recording a performance at a lower speed. In Logic Pro for Mac, you can speed up or slow down a project between −50 percent and +100 percent, which is between 50 percent and 200 percent of the original tempo.
In Logic Pro, click the Varispeed button in the control bar. ![]() Note: If you don’t see the Varispeed button in the control bar, Control-click the control bar, choose Customize Control Bar and Display from the shortcut menu, choose Custom from the LCD pop-up menu, then select the Varispeed checkbox. ![]() In Logic Pro, click the upper part of the Varispeed display in the control bar, then choose one of the following: ![]() Speed Only: Use to pitch shift the master output signal to balance the pitch change caused by varispeed. Only the speed changes, not the pitch. Varispeed (Speed and Pitch): Use to emulate classic tape varispeed, where the pitch changes to reflect the speed change. Varispeed and MIDI: Use to emulate classic tape varispeed (speed and pitch) and simultaneously transpose External MIDI tracks, quantized to semitones, so they sound at the same pitch as the project. Change the unit of measurement and adjust the valueIn Logic Pro, click the unit of measurement (%, bpm, st, Hz) in the lower part of the Varispeed display in the control bar, then choose one of the following: ![]() Percentage (%): Displays the unit of measurement according to percentage. Resulting Tempo (bpm): Displays the resulting tempo, dependent on the current tempo, which changes along with any tempo changes in the project. Note: The Tempo display in the control bar always shows the original tempo value. Detune (st): Displays the unit of measurement according to pitch change. Tuning Reference (Hz): Displays the unit of measurement according to tuning reference. Drag vertically on the value to adjust it, or double-click and enter a new value. ![]() Download the guides: Logic Pro User Guide: Apple Books | PDF Logic Pro Instruments: Apple Books | PDF Logic Pro Effects: Apple Books | PDF |
