Disklavier

Hi everyone,

I used to have access to one of the Linux tableted Disklaviers a few years ago but that is no longer the case. I've found a cheaply priced MX80 and I've done some research and read all the posts referencing it here but I still have a couple questions and would like some opinions.

My intended use would be to make MIDI sequences of things beyond my dexterity and then have the Disklavier perform them.

It's my understanding that the MX80 has the worst sensors and the fewest gradations on things like velocity and the smallest polyphony (16?). It seems to me that these things would be detrimental if I was trying to transcribe a performance on the keyboard into MIDI but I would think that I would be able to get sufficiently much variance in velocity and pedaling for playback. Yes or no?

I'm going to check this piano out on Monday. Does anyone have a MIDI file that would be a good test of the entire piano? Like something that does pianissimo to fortissimo across the entire range of keys with lots of pedaling. I don't care if it sounds like music or not. I would just like to evaluate the instrument without taking up too much of the seller's time.

Also, what sequencers are most of you using to create sequences (on the computer, not record from the keyboard) and/or play them back via the Disklavier? I'm particularly interested in what Linux users are using but am also curious to hear what people are using in Windows.

Anything else I should know about the MX80 that might not be readily apparent? Like if there was some major design compromise or there's any sort of problem they tend to develop over time.

Thanks for reading!
