I had problems running Jamstix with Cubase 7.5 on my mac. It never seemed to draw the window correctly or stay on top like I wanted it to. I found Jamstix worked fine with Logic and Reaper.
I just upgraded to Cubase 8 (64 bit) and now find that Jamstix works great! No Cubase windows problems at all. If you own Cubase, I encourage you to upgrade to version 8.

Unfortunately C8 on a Windows platform is not so great... and I'm having particular problems with JS. In contrast it was solid with Cubase 7.5.x

I never had C7 or C7.5 (other than the trial) so I can't compare (I can only compare to C6.5) but C8 on Windows 7 and 8.1 (I have it on two machines) in running very smoothly. Jamstix is also running very smoothly.
