Re: 1986 Disklavier midi play back volumne

2011-03-10 by jboxnz

Thanks for the tips. The piano is not excessively bright (at least to my ear) although it is noticeable brighter than my neighbor's Kawai US50. It is on carpet but against an internal wall (standard dry wall). I'll try put something between the piano and the wall to see if I can tune it down a bit.

Cheers

It is possible that some voicing of your piano, a rug under the instrument, and even a wool blanket or other baffling between the back of the piano and the wall behind would tone down the piano. This would mean that you don't need to go to such extreme lengths to edit down the note-on velocities.

What I did so far is that if the file has maximum velocity over 100, I'll first use the left slider on Veloset to move the whole range lower (to the left until the max is at 100, or all the way to 1), and if the max is still over 100, I'll then use the right slider to compress it. This way I think will give a theoretic broader dynamic range (1-100) for the midi file, however it means the file will have notes in the 1-30 range which maybe all be played by the piano at ~30, so the bottom part of the notes get compressed more while the upper part is less compressed.

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.
