The YDP-131 manual is not very clear about it, but the only place where it mentions that data from the MIDI IN is played is in the section where it de...

There are no padding bytes. Many (meta) events at the beginning of a track have a zero delta time. Please show an example hex dump. They only wa...

This depends on what programming languages you're comfortable with. "Control" is rather vague. What exactly do you expect the platform/library to d...

[quotePost id=18825]if you look at the structure of the four bytes making up the Header Length or Track Length, you'll find (as in so much with MIDI 1...

Historically, MIDI files have always used big endian, and this has always been the more common byte order for interchange and network protocols.

Hardware errors would happen randomly, not always after 5 seconds. But I know of no other setting that might help.

Then please also try to disable USB selective suspend.

This indeed sounds like an overzealous power-saving "feature". What is the exact name of the setting that you tried to disable? "USB selective susp...

The velocity affect's a single note's volume (and maybe other parameters). The expression (CC 11) affects the entire channel, and should be used by t...

You can use any host that allows to connect a USB device and has MIDI ports. The UMH-10 from DOREMiDi is such a device, but any other USB MIDI host sh...

The USB MIDI protocol (and all other USB communication) uses all four pins. But it is certainly possible to use USB to power devices. Please note t...

The bank number is a setting of the channel, so in theory, you do not need to repeat it for other Cx commands on the same channel x. But in practice, ...

Some software uses the range 0...127, some uses 1...128 (and this might be different for different parameters). You have to check what range your soft...

For Roland's list of these MT-32 instruments, see p. 186 of the SC-8850 manual. (The SAM probably does this for SoundCanvas compatibility.) The MT-...

The XK1 uses a 3.3 V supply. At that voltage, 120 Ω + 22 Ω actually is too much. And the inputs always should use 220 Ω. (The noise filtering is fine,...
