Tap Tempo lets you slave Digital Performer to a tap entered from any MIDI controller. You can use this to "conduct" your sequence and record these taps to the conductor track to create a tempo map.

To setup Tap Tempo in DP4:

• Goto Setup > Receive Sync
• Under Type of Sync, select "Tap Tempo"
• Under MIDI beat input data, you can select an external source such as your MIDI controller
• Make sure you select an Event
• Sync countoff beats is the number of countoffs before Tap Tempo starts
• Under Setup, click on Slave to External Sync (Command-7)
• Set your conductor track to record-enable
• Hit record, tap your event for the number you designated for countoff, and tap the desired tempo changes
