<div dir="ltr">Hi Andrew,<div><br></div><div>I see, my subject title is a bit confusing, better would be: How to distinguish different players in the <staffDef> and <staffGrp> elements.<br><div><br></div><div><span style="font-size:12.8000001907349px">"If you have two different staves, these are two different players, regardless of the label (a left and a right hand on a piano could be thought of as two different "players" since they're playing two separate parts)."</span><br></div><div><span style="font-size:12.8000001907349px">I strongly disagree on that, it is played by a single player and it is a single part. This is even more clear if you think about harp parts, (very often) one 'voice' (strangely called 'layers' in MEI) traveling across 2 staves.</span></div><div><span style="font-size:12.8000001907349px">Another problem is cross staff notes, in your opinion these are the same as something that would be called 'cross part notes' (since each staff is a part). Think about it, 'cross part notes'... I don't even know any contemporary composer who did this.</span></div><div><span style="font-size:12.8000001907349px">I think this information should be added to the MEI format, and I think it can be done with an attribute in the staffGrp element indicating that all staves in that group are performed by one player/instrument (or group of players, eg, 1st Violin).</span></div><div><span style="font-size:12.8000001907349px">This way you can keep numbering the staves top to bottom for the whole score, but it's clear which staves are played by the same player/instrument and should be grouped together when playing around with parts.</span></div><div><span style="font-size:12.8000001907349px">I agree that it needs to be possible to hide a single staff in a part with multiple staves, but semantically spoken it's a big difference with hiding a part.</span></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">At the same time it would be great to have another attribute in the staffDef element indicating that this staff is performed by multiple players, for instance 1st and 2nd Violins are notated as 1st and 2nd voice (again, called layers in MEI). This would be very helpfull in reading some chorus score's to (in the MEI examples this would clear up different parts in Altenburg_Macht_auf_die_Tor).</span></div><div><span style="font-size:12.8000001907349px"><br></span></div><div>To be sure we are talking about the same:</div><div>- staff: needed to notate music</div><div>- part: music performed by a single player/instrument</div><div><br></div><div>One part can be notated on multiple staves, multiple parts can be notated on a single staff.

<br>
Welcome to MEI!<br>
<br>
Are you looking for the equivalent of the MIDI instrument that would perform these parts? Or something else?<br>
<br>
If you have two different staves, these are two different players, regardless of the label (a left and a right hand on a piano could be thought of as two different "players" since they're playing two separate parts). If you have a staff that is "hidden" (for example, if you have an instrument that does not play on certain pages) you still need to define the staff and give it a number. This number should be constant throughout the score. If it does not play in a specific place, it will simply not appear in the measure (as far as I understand it).<br>
<br>
If you're in a renderer and you want to switch all the "n=2" parts off, then, you would simply hide it whenever you have <staff n="2" ...>. The "2" does not refer to the second staff on any given page; rather, it refers to the second staff defined in a score, regardless of whether it appears or not.<br>
<br>
