I have a MIDI digital piano that connects to a computer via USB (it also has a normal MIDI out port too) and I'd like to browse for software that lets me play music through my computer's speakers. I want to look through the options (including open-source candidates).
I just want to pretend it's a real piano and play some sheet music.
I'd like to google for this, but I'm not familiar enough with terminology.
So my question is:
What is the term for software that will convert MIDI input to audio and play it back immediately?
The askers of these questions seem to be seeking roughly the same thing as I am: Piano midi software How to use my mac and MIDI keyboard as a simple always-on piano Very portable MIDI synth
Is the software that I'm looking for called a MIDI Synthesizer? Or a Sound Module? Or something else?
Another way to phrase it: Given a vanilla install of an operating system, what types of things would I need to install (or run) to get audio output from my piano?
Note: Unlike the other linked questions, this question is not "which software should I use?"
Rather, I'm looking for the terminology so I can solve the question for myself (using search engines).
