Make a mashup

Drop an instrumental and a few acapellas, and the Key finder pitches and speeds each one to fit.

Line up the songs

1. Open the Key finder and drop an instrumental and one or more acapellas. You can also add songs by name or link.
2. The instrumental becomes the anchor: its key is the target and its tempo is the mix tempo. Every other track shows how far it is pitched and sped.
3. Check the chip beside the tempo: Great match, Good match or Hard match. Open it to see what each track needs.
4. Press play to hear them together.

To fit everything to another track, open its … menu and choose Fit the others to this track.

Arrange the playlist

• Drag a clip by its top strip to move it. Its beats snap to the anchor's. Hold Alt to place it freely.
• Drag a clip's left or right edge to cut it, and drag a top corner inward to fade it.
• Each track has mute, solo and a level. Drag the grip before a name to reorder, and double click a name to rename it.
• Minus and plus beside play change the whole mix's tempo. Press a track's key and speed to set its own.
• Pinch, or hold Ctrl or ⌘ and scroll, to zoom.
• Full screen, hold Alt or ⌥ and scroll, or drag the ends of the scrollbar beside the tracks, to make them taller or slimmer.

Split a song into acapella and instrumental

Point at a track and press the layers button, Split into acapella and instrumental. It takes about a minute and adds both parts under the track.

Change notes or record

• Edit notes (the tuning fork on a track) moves the notes of a sample, or turns minor into major. It works like the Note editor.
• Record adds a lane so you can sing over the mix.

Save the mix

Press Save to Aden under the playlist. Aden opens on a new track with the mix, in the target key and tempo, and each track as a stem. Songs you found by name or opened from Aden are linked as the originals, and their teams are asked to approve.
