I would like to know much more about MIDI controls

[IrionDaRonin]

I'm making electronic music since i was 14.
Then i started to make more seriously music in my computer since i was 20-21.
I always used my ears to make sounds, tracks, etc. Always from audio resources.

But now, i need to improve my knowledge about MIDI.
I know the basic about MIDI, note on, note off, velocity, what means, how to use, etc...
But now i'm aware that there are too many other parameters and terms which i don't know very well, what means, or how to use them. And i would like to improve that knowledge. I like to learn so much.

For example, Aftertouch, Breath, Expression and these kind of "strange" things.
I tweak some of them in some softsynths, but i can't hear any difference in the sound.

My question is easy. There is anywhere over the net, a guide about the meanings of each MIDI control? About how to use them? about how works? about how affects the sound in a synth? Etc...

It would makes very happy to learn more about all this and improve myself, going beyond my knowledge about MIDI controls.

Have a good day and thanks in advance

you wouldn't hear any difference unless you'd assigned those instructions to a target that takes their meaning; just as you wouldn't hear a note on without an instrument that knows that code. MIDI doesn't do anything without an object to carry out the instructions.

the meanings ascribed to CCs in the original MIDI protocol had everything to do with hardware synths and the way they were hard-wired; CC1 was for the modulation wheel; Roland made an 'expression pedal' so CC11 was called 'expression' and it did something for the synth. The meanings are more or less fluid now. You have continuous controllers over a range and you have switches, on/off. EG: CC 64 'sustain pedal' is up, off, or down, on. You can't make CC64 do more than this.

There is MSB and LSB, most and least significant bytes, suggesting 'coarse' and 'fine'. EG, 'CC33 mod wheel' may have meant something to this or that manufacturer. It has no meaning in a software sequencer; there are 0-127 values for either. The meanings are what you make of them, restricted to some extent by the design of the synth that is the target, depending.
