| MIDI (musical instrument digital interface) is a signal that describes a note being played. It contains really very little information:
duration of note (how long)
frequency of note (what note)
attack of note (how hard it is hit)
I think that's it - that's all that's coming readily to mind, anyway.
You need a processor to convert those signals into sounds that resemble instruments. The processor will have stored "samples" of what a real instrument sounds like (or an imaginary instrument), and will then play that sample back in the manner you described using your MIDI controller.
A MIDI controller could be:
a keyboard
a footpedal
an electronic flute
a bass with MIDI pickups
a violin with MIDI pickups
etc.
If you plugged a MIDI keyboard into your computer, your computer could process the MIDI signals and convert them to sounds. You could send the resultant output to your bass amp, yes.
