and what IS your hardware?
I have no problems here with MS or Samplitude MIDI recording.

Thanks for the response. XP P4 3GHZ, 1.25GB RAM. Input is Behringer UMX25 thru USB. Works with a bunch of other audio software (like FL Studio, Reaper, Sony Acid Music, Ableton Live, Tracktion et al).
My wording was misleading: it recognises the input OK, it just stops accepting input after a recored session (no meter reading or sound) until I reset the record arm. Also works if I have channel armed then start record (R key) and play a note during count-in. If I wait until recording starts it's not re-armed - although the arm button is still lit.
I'm having trouble coming up with a sensible explanation for this behaviour. I haven't got the keyboard set as a controller, so there shouldn't be any feral signals running about.
