Re: [disklavier] Disklavier Mark III MIDI trouble

2015-08-25 by Spencer Chase

The delay should delay all events, i don't see why it would mess up repetition. you can use my virtual keyboard program to send repeated notes at various velocities to see exactly what the piano does on each note. this can help you find where the problem is. is it all notes or just some? the virtual keyboard (PC only) is on the download page of my web site. i also have programs that analyze midi files with respect to note gaps etc, so if your piano is performing correctly it can point out midi files that have repetitions that even a properly functioning one will not play.

a keyboard should send note off or note on velocity 0 events when the key is released. there may be some wacko ones that don't? my virtual keyboard definitely does send vel 0 notes to terminate the keypress.

you can also monitor all midi activity with midiox (google it) so you know what is actually going out. it is free as is my virtual keyboard.

if you have severe short note and repetition problems it suggests action problems, lost motion or tightness. is the action sluggish to hand play? if so, you need to fix it as the DKV can not overcome this sort of problem no matter how carefully it is regulated.

Good evening, everyone.


Carlos, is the MIDI Input Delay (500 ms) on your Disklavier set to ON or OFF? Once I know that, I can provide further explanation.

Hi everyone, again. Further to my earlier questions about my Mark III DGB1CD disklavier, I am having a new problem about which I could use some advice. When attempting to play MIDI files off my mac computer (usually using the notation program Finale) through the disklavier, 1) the piano is not playing very soft notes (marked below "p", or a MIDI value below 40) The keys (and solenoids inside) do move a little, but no hammer action takes place. Also, 2) when there are fast, repeated notes, the disklavier only plays the first note on a sequence, not the rest. Could the latter be because the piano only receives "key on" signals?

I hooked up an external keyboard to use as a MIDI master, and the same problem persists: Neitehr very fast, nor very soft notes are played on the disklavier.

Can anyone suggest a solution or workaround for any, or both of these problems? Can I have the disklavier mechanism re-calibrated, or adjusted so it can play soft, fast notes accurately? Could this be a software problem?

Thanks!!

Carlos
