Mixer access for plugin development

Hello,

thank you all for your feedback. It helped me a lot.
It took me some time to understand some concepts of museScore and plugin development.
(and how to read the documentation)

I almost finished a plugin to set note velocity but then I found out about museScore parts settings.
These allow access to some parts of the mixer, e.g. volume and mute.
see:
curScore.parts[0].volume = 100
curScore.parts[0].mute = true

Here is the plugin I do currently use for reference:

{syntaxhighlighter title="plugin"}
import QtQuick 2.0
import MuseScore 1.0

MuseScore {
version: "1.0"
description: "Exports score as mp3 as well as every Choir voice twice as loud as other voices"
menuPath: "Plugins.Choir Rehearsal Export"

// Set all parts to volume specified by vol
// disable mute if enabled.
function mixerVolAll(vol)
{
var part
for (var partIdx = 0; partIdx < curScore.parts.length; partIdx++)
{
part = curScore.parts[partIdx];
//console.log ( "part partName/shortName: " + part.partName + "/" + part.shortName);
part.volume = vol
part.mute = false
}
}

// not everything needs to be exported.
// use export only for Choir voiced but not for Piano
// it is assumed the piano is always the last part
function getMaxChoirPart()
{
var maxPart = 0
var part
for (var partIdx = 0; partIdx < curScore.parts.length; partIdx++)
{
part = curScore.parts[partIdx];
if ("S." == part.shortName) maxPart++;
if ("Mzs." == part.shortName) maxPart++;
if ("A." == part.shortName) maxPart++;
if ("T." == part.shortName) maxPart++;
if ("B." == part.shortName) maxPart++;
}
return maxPart
}

// set the volume of a certain part to "vol"
function mixerVolPart(vol, partIdx)
{
var part
part = curScore.parts[partIdx];
// console.log ( "part partName/shortName: " + part.partName + "/" + part.shortName);
part.volume = vol
part.mute = false
}

// Get a Name/Volume pattern to be used in the export filename
// e.g. S.50_A.100_T.50_B.50
function namesVol( maxPart )
{
var part
var retName
retName = ""
for (var partIdx = 0; partIdx < maxPart ; partIdx++)
{
part = curScore.parts[partIdx];
retName += "_" + part.shortName + part.volume
}

return retName
}

onRun:
{
var expName // filename for export

if (typeof curScore == 'undefined') { Qt.quit()}
console.log("parts: " + curScore.parts.length);

// set Volume of all parts to 100
mixerVolAll(100)

// export score as mp3 with all voices at normal
expName = "D:/" + curScore.name
expName += ".mp3"
console.log ( "createfile: " + expName);
writeScore(curScore , expName, "mp3" )

// get number of all parts without piano
// for every choir voice (eq. part) set all others to volume 50
var maxPart = getMaxChoirPart()
for (var partIdx = 0; partIdx < maxPart; partIdx++)
{
// all others to 50
mixerVolAll(50)
// single choir voice to 100
mixerVolPart(100,partIdx)

expName = "D:/" + curScore.name
expName += namesVol(maxPart) + ".mp3"
console.log ( "createfile: " + expName);
writeScore(curScore , expName, "mp3" )
}

// when finished set all back to normal
mixerVolAll(100)
Qt.quit()
} // on run
}
