The Yamaha AN1x Synthesizer mailing list

Sorry this isn't directly related to the AN1x, but I'm getting frustrated
and thought someone here could help.

Basically, today I set up my MIDI gear for the first time since I moved
house. I'm using exactly the same setup. I tested it all out by running a
few older Cubase arrangements that I knew well, and everything worked fine
until I tried to enter some MIDI data from my keyboard. When the sequencer
is stopped, no MIDI data is coming in (the MIDI in indicator won't light
up). When I start the sequencer however, I can hear what I'm playing (and
the MIDI in indicator lights up), but there is some kind of latency. The
notes I play on the keyboard only sound after a delay and sometimes don't
sound at all. I am using Cubase VST 3.5 and it has always worked fine
before.

Before I set up my external MIDI gear I installed the Reason demo which I
have now uninstalled. Could this have caused any problems?

My setup is this -

AN1x MIDI out > PC MIDI in
PC MIDI out > A3000 MIDI in
A3000 MIDI thru > AN1x MIDI in

Please can anybody suggest absolutely anything, as I'm desperate to get
making music again!
