Disklavier

Good evening, Tony.

<< thanks for the advice. I thought I'd email you directly since you were 
kind 
enough to try to help me. I guess I should elaborate on my set-up a bit as 
my situation is a bit unusual.>>

I am happy to try to help.

<<I have a MX100A disklavier-no tone generator and only two midi out 
settings-delay out/keyboard out. The midiman USB device has three lights 
that indicate 1. USB activity, 2. Midi In activity (signal from piano) and 
3. Midi out activity (signal from Macintosh).

Micrologic is a sequencing program that takes advantage or links through 
OMS...

What is happening when I am set up now at the midiman level is:
1. a constant light indicating USB activity>>

The Disklavier is one of many Yamaha products that send MIDI messages called 
active sensing. Therefore, I would expect that the MIDI In light would always 
be on and that would probably cause the USB light to be on, too.

<<2. I can consistently get a test signal from OMS to actually generate a 
Midi 
Out light activity as well as a random key played on the MX100.>>

This means that OMS and your connection to the Disklavier are fine. If you 
had a tone generator to receive on all of the other MIDI channels, you would 
hear quite a noise each time you did an output test within OMS Setup. Since 
you do not have the tone generator, you are just hearing whatever random note 
was sent on the MIDI channel that the Disklavier is set to receive on.

<<3. There is a constant light on indicating Midi In activity (when the piano 
is set to delay out.>>

As I mentioned, this is normal. However, if you play and note AND the 
Disklavier is set to Keyboard Out, then I would expect that light to flicker 
as data is sent through the interface. Similarly, if you leave the Disklavier 
set to Delay Out and try playing a disk, I would expect that light to flicker.

<<However I can't get the sequencer software to send a signal of any sort as 
determined both at the midiman or at the piano level. The sequencer does 
show tones being generated, but there is no activity at the midiman level...>>

This is definitely a problem between your sequencer and OMS. I am not sure 
what to say about that. If you go into your sequencer's MIDI setup dialog 
box, you should have several choices for MIDI Out that are offered by OMS, 
because OMS, theoretically, can talk to many different devices. I would check 
out that dialog box and pick the output setting that matches the output port 
on your MIDIMan interface as shown in your OMS Setup program.

I guess at this point the problem is somewhere between the sequencer and 
OMS... >>

Let me know if I can be of further help.

Regards,
George
