This happens when a file is written for a specific synthesizer, and the settings are not made with standard MIDI messages but a SysEx parameter dump. ...

ALSA's buffer size is shown in /proc/asounc/cardX/midi0 when the device is open, and is 4 KB by default. In general, you have to assume that the sp...

MIDI itself has no concept of tracks; there are only channels. If your file has two tracks with bank selects and program changes on the same channe...

Does this happen with all software? Can you show exactly what bytes are wrong?

What happens with two identical note-ons is not defined by the MIDI specification. (The SMF specification requires that every note-on has a note-off; ...

The resulting sound depends on the synthesizer. Was this file written for a specific one? What exactly do you mean with "2 notes in a row"? Some sy...

A USB/MIDI cable is not a simple cable (with nothing but wires), but contains some chips. So strictly speaking, it is not a cable but an interface. Bu...

Yes, you need a USB/MIDI interface. It requires a microcontroller to handle the USB protocol, but this can be integrated in a large plug. The only ...

MIDI is a current loop. At the transmitter, pin 4 is connected to power, and pin 5 is switched to ground to make current flow. At the receiver, the op...

Asking here is OK. There's nothing special about legato; only the device that actually generates sounds has to decide whether two notes are near en...

Yes. But reducing the overall latency from 1.4 ms to 1.2 ms might not be worth the effort.

Both classic MIDI and USB MIDI have a latency of about one millisecond, so it does not make sense to have a scan interval much shorter than this. Y...

The General MIDI 2 specification says that "The velocity effect on volume is not defined". But it does define the response to the Channel Volume and E...

Merging without SysEx is easy. A simple algorithm would work like this: * There are three states, for when port 1/2 is in the middle of a command,...

These tools can be called from a .bat file (or better, a .cmd file). But you still have to write that file. To get a .mid file, record the MIDI com...
