MIDI driver problem

MIDI driver problem

2004-07-16 by Davis2002

Group:

I have been driving my DKV (an old wagon grand) via MIDI cables from a Windows 95 machine for years. I'm now not sure that it ever worked completely correctly, but it took a definite turn for the worse after I tried to use RealVNC to control it through my home network (got too lazy to walk into my computer room to change my selections).

In any case, the symptom is that notes seem to be getting cut short, with short notes quite often getting cut so short that they don't even sound. I suspected that the RealVNC driver was screwing with the interrupts, but uninstalling it didn't seem to solve the problem. Any ideas?
Also, does anyone recommend a USB to MIDI setup that runs reliably on XP?

Good morning, everyone.


I have been driving my DKV (an old wagon grand) via MIDI cables from a Windows 95 machine for years. I'm now not sure that it ever worked completely correctly, but it took a definite turn for the worse after I tried to use RealVNC to control it through my home network (got too lazy to walk into my computer room to change my selections).

I suspect that your Disklavier is set to receive and respond to MIDI data in real time (i.e. no delay). The result is that note-off messages are being received and acted upon before the mechanical action has finished playing the original note-on messages.

If I am correct, you can reset the 500ms delay for MIDI input and the problem will go away.

Also, does anyone recommend a USB to MIDI setup that runs reliably on XP?

As far as I know, the Yamaha UX16 and UX96 interfaces work just fine, assuming that you have installed the current drivers.
