To answer your first question:
If my idea were to be implemented, it would probably end up being found in ether the weapons or entities tabs.

And to answer your second question:
The music would probably have to be mapped out in the form of coordinates with the lowest note being 1,5 (that's Sring 1, Key 5) and the highest being 4,0 (String 4, Key 0)

And to answer the question that you might have "waiting in the wings":
Have you watch a playthrough of Symphonia (Not to be confused with Tails Of Symphonia (that's a completely different game entirely!)) where music is used as a game mechanic (e.g.: Fast Travel and opening Special Doors (tune of Way Fare and Song Of The Fields respectively))?

how do you even use it?

where would you find it?

You "could" add an animation of the bow rubbing according strings by mapping them to (1, 2, 3 and 4) and add an animation for the hand and finger positions according to each note for the corresponding string being played getting mapped to (5, 6, 7, 8, 9 and 0).
you could also have it set up so that the violin can be taken out and put away by using the (+) and (-) keys respectively.
(just to clarify: Its the number keys at the top of the keyboard and the (+) and (-) on the number pad)
(I hope these ideas help with improving and streamlining your addon so that it can (eventually) stand separately from the "Playable Piano" addon as a true musical instrument SWEP)

Just as I thought

Xardes > Secunda from Skyrom

What is that song u playin?

no pics no clicks

why not just change some variable names and make it to where you can have both?

nice

Nickaffar > Sure, soon. ;)

You think you could update it to also change the model and animations to a violin maybe?

ah okie

Ivretor -> Exactly, this is the default playable addon, but with a modification on the sound.

wait do i have to uninstall the deafault piano, install this mod, then install default piano?
