Wow, I went through this very thing about 6 years ago. Same ordeal. They took everything, instruments, computer, amps, drums, all of it. I lost all of my projects and everything I was working on. All of those years of work, just gone.
Insurance didn't replace everything - we had replacement level coverage, which is the better kind, but there's still depreciation so I was only able to replace about 70% of what I lost. And that does nothing for the sentimental value of my guitar that my wife had bought me 20 years previous.
Bit, I hope you handle this better than I did. I fell into a deep depression for a long time and I've never quite returned to form. I don't record nearly as much, and I constantly think about all of the work that disappeared and the energy and time it would take to attempt to recreate it.
This is partly why I firmly believe in death as justice for stealing. Maybe not for stealing a doughnut, but sweat and time go into things that we own. We rarely get things for free - we work for them. They are NOT just "stuff", easily replaceable. Bullsh*t. Everything you own cost you time and energy to acquire - lots of it. To steal "stuff" is to steal time out of your life - directly. And that's before we get into the sentimental nature of it all.
Death to thieves.
