Re: [disklavier] Re: MX80 Testing and Sequencers

2010-08-08 by Spencer chase

i wrote the keyboard program after searching for something similar. there might be something now but there was nothing like it when i wrote it. you can sweep through all the notes at different velocities and can set timed repeats. i wrote this specifically to test player pianos quickly and easily. it finds both player and action problems easily.

Hi Spencer,

Thanks for your reply.

Yeah, I was planning on taking a laptop with a MIDI interface. I'm not looking for software to send MIDI data though. There's a lot of that freely available for Linux.

What I'm hoping for is that someone has already made a midi file that just runs through all the keys and pedals at all the velocities so I can just quickly test the complete range of functionality of the piano much more quickly than I could by hand. I could make such a file myself but I'd hate to spend the time doing unnecessary work if there's already a resource available.

Also, I don't remember how the pedaling works. IIRC, full pedaling is on one channel and partial pedaling is on another channel but I don't remember what those channels are or what data to send on them.

Thanks!
