The control panel contains options and settings applying to a score. At the top of the Play screen, tap the cogwheel 
or pull down the horizontal bar just below the song title.
Title – you can type a title for your song here. If it is a PDF, the name of the PDF will appear here by default
Composer – if you add a name here you will be able to search by composer in the Documents screen
Status – this tells you the processing status of your score. If it indicates that there is a problem, try tapping the rescan button
Rescan – to the right of the Status is a circular ‘recycle’ icon. This rotates to show when scanning is in progress. You can rescan the music at any time by tapping this icon
Dynamic range – this tells PlayScore 2 how much to vary the volume according to markings like f, p, crescendos, diminuendos, accents etc. If you slide it to the right you will hear the full dynamic range in the music. All the way to the left causes the music to be played without dynamics
PDF process quality (PDF scores only) this allows you to alter how the music is processed. In general this is a quality/speed tradeoff, but some scores translate better at a lower or a higher setting and it is worth trying different settings for best results. For some poor quality scores it is possible to find a ‘sweet spot’ where the music sounds best
Play repeats – with this setting on, PlayScore 2 plays any repeats in the music. Note that this does not affect MusicXML export which always reflects any repeats
Auto transposition – turn this on to set transpositions appropriately for transposing instruments in mixed-instrument scores. For example, if your piece is for clarinet and piano, and the clarinet is in Bb say, auto-transposition will make the clarinet part play at the pitch a clarinet would have done. See Transposing instruments and transposition for more information
Staff voices – turn this on if you want to separate parts printed two to a staff. It allows you to set the volume for upstem and downstem parts separately
Swing – turn this on if you would like to hear the music in swing style.
When swing is enabled , even quavers (8th notes) are (approximately) tripletised as heard in swing music. The first quaver becomes the length of two triplet quavers and the second one.
This video shows the use of the Swing feature with French baroque music in inégales style.
Error correction – this is an auto-correction feature that can spot mistakes in a score or or recognition errors. In most music it works well, but in some music where there are false relations (notes played together on the same degree of the scale but with a different accidentals) Error correction may try to ‘correct’ these. If this happens, turn the setting off.
