MIDI Forum

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...

MIDI streams do not contain timing data. You have to parse all incoming messages in order to get running status at the output correct. And you have...

To send individual messages, use a tool like SendMIDI. Bit it might be easier to record the entire light show as a .mid file, and play it with a tool...

Here, "=" does not really mean "equals". NRPNs (and RPNs) use an additional indirection to allow more control numbers. You use controls 98 and 99 ...

… but very few devices support it. I know only of software synthesizers.

It resets all parameters, so it should come before any other message sent to the device. It does not really matter whether it comes before or after so...

Can you attach a .zip with both files?
