Hi,
You can either record initially into two hands (two staves) by selecting both staves when starting the recording.
1. Select both staves (click the Staff Select button for each while holding the "Shift" key)
2. Start recording - the notation will be split between the two staves when it's transcribed.
Alternatively, you can use "Staff/Split Hands" after the recording to split the notation into a two-hand (two staves) part.
1. Select the staff.
2. In Staff menu, click on "Split hands" - it will show you your already selected staff (or you can select it now if you didn't in step 1.)
3. Click OK - the notation gets split between the two staves.
Enjoy
Sherry
