Render offset (ms)

Type: range

Default value: 0

Min: -250 Max: 250 Step: 1

Anacrusis beat amount

Type: range

Default value: 0

Min: 0 Max: 4 Step: 1

You can use this setting to define a number of beats that are meant as an anacrusis or pick-up in the song. Some MIDI files handle this themselves by setting a different time signature for the first measure, but that's not guaranteed.

Type: boolean

Default value: false

Enable this if you're MIDI device has less than 88 keys. Notes outside of the set range do not need to be played for the song to continue in playalong mode. Use this in combination with the transpose setting to customize setup your MIDI device.

Default value: true

If enabled, the app will attempt to format multiple staves so they are aligned. This may cause problems on complicated arrangements and if there are many tracks.

Use this to manually set a time signature for the song. This will causse all time signature events from the MIDI file to be ignored.

Minimum note denomination

Hide rests below denomination

Type: list
