There may have been an issue with the MIDI ports - not sure what, but Tim Humphries' SAM MIDI Sequencer which I used with mum's keyboard hooked up worked fine.
I heard of no issues with…

Pressing keys seemed to effect the palette interrupts on the screen.
Perhaps this is the issue? Not really a major bug in that case.
Hmm, I wonder if it only…
Hmm, I wonder if it only affected MIDI IN/THRU then rather than output? - I don't have a MIDI keyboard or a copy of the Sequencer otherwise I'd give it a go to try and reproduce it.
Yeah actually I noticed this…
Yeah actually I noticed when using Flash with a Midi keyboard attatched.
