Re: [disklavier] Re: Sustain Pedal rattling on dkc100rMK2 and C7 Conservatory

You certainly have something peculiar going on.  The next step should be 
to try to discover if the problem is within the DKV or within Cubase and 
the computer. Do you have a friend with a different computer, sequencer, 
and cable that you could substitute for yours?  Or, can you borrow some 
simple synthesizer that you could substitute for the DKV?

Have you experimented with the MIDI input settings?

Contact me privately if you need a simple MIDI test file guaranteed to 
play on a Disklavier.
