Musician currently plays its samples using the SFX channel. As discovered in this discussion, each sound channel appear to have its own fixed cap for simultaneous sounds, regardless to the total number of sound channels (Sound_NumChannels). For example, SFX can handle 15, Dialog 20 and Master 30 which means that 15 + 20 + 30 = 65 simultaneous sounds can be played if we use those 3 channels.

A quick experiment shows that setting Sound_NumChannels to 128 and playing music using Master, SFX and Dialog channels simultaneously just sounds amazing and definitely resolves the limited polyphony issue.

The drawbacks are :

• It's no longer possible for the player to adjust Musician's music along using the SFX volume slider
• SFX and Dialog channels volume should be set to the maximum to avoid notes played in these 2 channels to sound quieter than the ones in Master
• The music can be insanely loud and audio can clip, with no other ways than reducing the master volume.
• The player should set Sound_NumChannels to 128 which is not possible using the audio settings panel, but fully supported

The solution is to allow the player to choose which channel(s) they want to use with Musician in the add-on options panel, following this order :

Master (30) > SFX (15) > Dialog (20)

• By default, all 3 channels are selected.
• If the SFX channel is checked along with Master, the SFX volume channel is automatically set to 100%
• If the Dialog channel is checked along with Master, the Dialog volume channel is set to 100%
• If only SFX and Dialog are used, the volume of the quietest channel will be set to the same amount of the loudest one.
• The amount of Sound_NumChannels is automatically increased if needed
• If none is selected, music will be played in SFX only and no additional audio setting will be changed

The "Audio channels" section will consist in 3 checkboxes indicating the resulting available polyphony. A small text is added to explain the behavior and which audio settings will be changed.

Audio channels

Check more audio channels to increase the maximum number of notes Musician can play simultaneously. Depending on the selected options, some audio settings will need to be adjusted.

[x] Master (30) > [x] SFX (15) > [x] Dialog (20) ==> Max polyphony: 65

(i) The volume of SFX and Dialog will be set to 100%.
(i) The number of audio channels will be set to 128.
