Sam, I think that the variety of scenarios that have been discussed have confused things. So, I'll lay out the information in a different way:
(1) Playback from internal memory or floppy disk
The MIDI Out port automatically works. All data is sent out the MIDI out port EXCEPT for the data that is played by the piano itself. The MIDI data that is sent to the MIDI Out port will be in sync with the playback of the piano itself.
If you want to send out ALL recorded data during playback (including the data that is intended to be played by the piano), you have to turn on the feature called Piano Part Ensemble Out.
(2) MIDI Out vs. MIDI Thru
You have two choices for the MIDI Out port: Keyboard Out and Delay Out.
If you choose Keyboard Out, the data that you generate by playing the piano yourself in real time is sent out the MIDI Out port without delay. I believe that I am correct in saying that on a Mark II, MIDI data that arrives at the MIDI In port is not sent to the MIDI Out port in this scenario. However, MIDI data that causes the keys to move will be sent to the MIDI Out port.
If you choose Delay Out, the MIDI Out port because a MIDI Thru port. In this scenario, the data that you generate by playing the piano yourself in real time is not sent out the MIDI Out port. Instead, whatever comes in the MIDI In port is passed through to the MIDI Out port. I am reasonably certain that if MIDI In is set to Real Time, there is no delay when the data is passed to the MIDI Out port. If MIDI In is set to the 500ms delay, that same delay is applied to the MIDI Out port.
(3) MIDI In: Real Time vs. 500ms Delay
It is very rare, with a Mark II, that you would want to set MIDI In to Real Time. If you do, playback by the piano becomes sloppy as the timing of each note is related to velocity of each note. Loud notes will be heard sooner than soft notes and rapidly repeated notes will not speak well. All notes will have some amount of delay.
In the case of a Mark IIXG or later Disklavier with an internal tone generator, there are times when you might want to set MIDI In to Real Time. Generally this is the case when you are going to play the piano yourself and are working with interactive MIDI software that only sends data to the Disklavier's internal tone generator. In that scenario, you might want the internal tone generator to respond without delay.

There is one problem, however, with your last scenario ("If i want to play virtual piano in Computer from silent DKL...): When you change MIDI Out from Delay Out to Keyboard Out, the MIDI Out port no longer functions as a MIDI Thru port.Pianobench, i was thinking that I would just have to change that one setting when I wanted to play virtual piano from silent piano, and toggle it when I go from that mode to multi-channel playback mode. Does that make sense?
SamGood morning, everyone.
Sam, assuming that you are not going to upgrade your Disklavier with a DKC-850 and enjoy the benefits of an integrated tone generator, your diagram is the way to go.There is one problem, however, with your last scenario ("If i want to play virtual piano in Computer from silent DKL...): When you change MIDI Out from Delay Out to Keyboard Out, the MIDI Out port no longer functions as a MIDI Thru port.Regards,PianoBenchOn Jan 19, 2014, at 12:42 AM, Skanter123 wrote:

SamGood evening, everyone.
Sam, this procedure does work with the Mark II. This Disklavier does not have a MIDI Thru port. Instead, the MIDI Output port functions as either a MIDI Output for or a MIDI Thru part. In the latter case, a 500ms delay is applied.To use the MIDI Out port of a Mark II as a MIDI Thru port with a 500ms delay, change the MIDI Out setting from Keyboard Out to Delay Out.Regards,PianoBenchOn Jan 17, 2014, at 3:07 AM, Skanter123 <skanter123@...> wrote:Send your MIDI data to your MPX100II MIDI In port.

SamSend your MIDI data to your MPX100II MIDI In port. Connect the MU50 to the MPX100II MIDI Out.This way the 500ms delay is incorporated in both the Disklavier and the MU50.BillSent from my iPhone.Hope I'm not wearing out my welcome with so many questions from a new user, but here's another.The MPX100II came with a MU50 XG external tone generator (and powered speaker) probably because this model was released before this was b uilt-in to the Mk II XG disklaviers.I assume one can use MIDI thru to connect both DK and external module, but what about the 500ms delay of the dk when receiving MIDI data, preventing everything from syncing up? There are latency settings in some advanced sequencers I have, but I was hoping there would be a simpler way to play back multi-channel MIDI files...Has anyone else tried this?Thanks in advance...
