The V3.0 midi don't work at all for me. Not on Win2k, not on W98, nor XTC nor Classic Pulsar mode.
Luckily I got AMT8 for mide, but Pulsar remote control is also unpossible.
And I've never had a problem with this, I think it is because I decided long ago to only use the Pulsar hardware MIDI ports and bypass "Seq Midi" altogether...
I think the software MIDI should be working good now, maybe I will switch
