Re: [disklavier] Re: MX80 Testing and Sequencers

2010-08-10 by Spencer chase

as you know, windowz sucks. i wrote the keyboard program for windowz because that is what most people use. the timing of the repeated notes can be messed up by background tasks so if you really want to check for even repetition you should not have any other stuff running and don't move the mouse while a note is repeating. works fine on a relatively fast( 2ghz +) computer.

be warned that you will probably find all sorts of horrible things wrong with any dkv that has not be carefully regulated.

Hey Spencer,

Thanks again for your reply. I will boot up Windows someplace and check it out!
