Leeneia (re "Music Star MIDI controller"), any external MIDI instrument only relies on a MIDI interface. Nowadays very few computers offer the original MIDI plug (round, with five pins). If your computer is one of those few, you may worry about OSes supporting it. More likely, you are already using a MIDI-to-USB adapter, otherwise you can buy it for few bucks. Then you are OK with all OSes and computers for the next, uh, 20 years.

Bad experiences can teach us lessons, but only if we ask and listen carefully.

The Windows philosophy has its principal flaws, as frequently pointed out, above and elsewhere. We need completely new strategies against spyware and other malware; the first step being not to rely on a single OS or browser whenever we can avoid it.
