Hi, there are a few examples of MIDI using V-USB on the Objective Development website:

https://www.obdev.at/products/vusb/prjall.html

The silly synth was made by using the report descriptors from one of those examples (it was a midi controller I think), enabling the WriteOut functionality in usbconfig.h, and putting my synth code into that function. There are other examples there which already do midi out though, that might be more helpful.

oh and also a great code for you to uptate the firmware on the attiny is use the digispark bootloader.
what it does is enter on boot mode and then enter on the execusion mode

Ha, I like your cardboard box for it.

You might consider putting the source code on github too, along with the hex file. I find it really useful when I go back to an old project to find everything in one place.

Next up, get a piezo buzzer and get it to play some tunes.

What does the error say exactly?

I usually use avr-gcc (or WinAVR), Atmel Studio can be a pain.
