Coz the Shroom

Hey everyone, I have been recording a lot of my music through a Soundblaster Live! soundcard I purchased in the late 90's and last Spring when Windows XP went into "unsupported" I found that Creative Labs built an 8 year life span into their soundcard and DID NOT update their driver for the newer OS's that are out there. I decided to dual boot my computer in linux and take XP offline so I could continue to use XP-- and this worked well until I recently lost the drive that had XP on it and had no installation disk for windows.
I am now running on Linux with Windows7 in a virtualbox, and while this works well for most audio applications, one thing that I absolutely do not have is MIDI capabilities, which is a shame! I have a yourock MIDI guitar controller which is MUCH better for the way I play and record than using a keyboard, plus hundreds of awesome soundfonts, and I have no clue how, when or if I can ever use this stuff again. If there is a program I can replace cakewalk9 with in Linux, that can also communicate with my obsolete soundcard, I'm hoping someone is a linux and MIDI expert enough to help me with. I am currently using linux mint 13 (won't expire until 2017, unlike the newer builds) and it talks to my soundcard with pulse audio control. There is absulutely no way to access any MIDI functions with pulse, though. Hopefully someone can steer me to a solution.
