Disklavier

Dear PianoBench and others - I just want to say how absolutely amazed I am at your body of knowledge about all things MIDI and Disklavier. I LOVE my DC4M4, but mostly I just play it. I have so little knowledge about how it actually works, though I do play around with it as much as I have time for. I have bragged to others many times about the depth and breadth of knowledge available here in this forum. I continue to be impressed.

Maybe someday I'll learn more! Thanks to all of you who so willingly share your wisdom, experience, and resources.

Shelley

Good evening, everyone.

I hope that someone from Zenph will speak up regarding the Mark IIXG Pro and the Mark IV Pro. I have not had the opportunity to do serious, back-to-back comparisons. I can tell you that the Mark IIXG Pro records pedal movement on a scale of 0-127 and that the Mark IV Pro does it on a scale of 0-255.

You asked about what you sacrifice when you replace the Mark IIXG Pro with a DKC-850 control unit. You lose the following:

--Playback of XP Data
The DKC-850 does not playback XP song data. (It does, however, record XP data.)

--Sending XP Data On/Off
The DKC-850 does not send XP data although it does send aftertouch data for silent notes.

--Receiving XP Data On/Off
The On/Off selection feature is missing. I don't know if the DKC-850 responds to that kind of data.

--Keyboard Out Split/Transposition
This option is gone.

--MIDI Thru2
This feature was previously available in order to allow you to connect an external tone generator. The incoming MIDI data stream would get the 500 ms delay applied to it before it was passed to the MIDI Out port. This option is gone.

--Piano Part Ensemble Out On/Off
The DKC-850 gives you an opportunity to designate MIDI Out as either Keyboard Out or Ensemble Out. If you choose Ensemble Out, by default, the old control units and the DKC-850 do not send the piano part of a song out the MIDI port or USB MIDI port during playback. The old control units, however, gave you an option to turn on Piano Part Ensemble Out when you turned on Ensemble Out. This option is gone.

--Voice: Option to have Piano Tone On or Off
When in Quiet Mode, it used to be possible to have the Piano Tone On while layering another voice on top. This feature is no longer present.

--MIDI Input Choice
The choices for MIDI Input used to include ## on Mark III, Mark IIXG, Mark II and other models. When this choice was selected, the piano would not play any of the incoming data and all data would go to the tone generator. This feature is not present on the DKC-850.

Helo,
Great explanation.

How does a Mark IIXG Pro compare to a Mark IV Pro as far as playback resolution and dynamic range? And what do you sacrifice coverting a Mark IIXG Pro to a DKC-850 in such comparisons?

The original Pro and subsequent Pro models have been unsurpassed in this regard and offer more resolution in between the traditional 0-127 velocity measurements. The Mark III, current E3, and Mark IVs non-Pros also have a much wider dynamic range compared to the early model instruments.

You will never be able to change the capabilities of the piano by modifying the software but you can achieve a better match between the source and what the piano wants.

However the loudness of samples with note velocity 5, 10, 20 and 30 are almost the same (all pretty loud to my ear), while those with 40, 60, 80, 90 and 100 have discernible difference, progressively louder).

The S/N on the piano indicates it's a 1986 model, although the test menu on the controller seems to show 1993 firmware (Maybe a retrofit system). It looks like a MX80 unit with separate control unit and has the same physical layout and test menu as the MX80 according to the service manul I found on the web.

What I found is that the piano seems to play at same volume no matter what I do with the velocity of the midi files (I use Veloset). Also for soft notes it also plays quite loud. Say for a midi piece with note velocity ranged from 10-100, all notes seems were played at same volume.
