I recently purchased a Yamaha Midi keyboard. I have been using Audacity for some time now so a lot of my work is saved as Audacity projects. I just found out that Audacity does not support Midi, which is weird because it’s just another instrument, and we are able to plug in other instruments to record so it shouldn’t be a USB issue… I really can’t afford to redo everything in a different program.
Audacity has some VERY LIMITED [u]MIDI capability[/u]…
which is weird because it’s just another instrument,
Quite a bit different from a guitar! 
Some keyboards support audio via USB (like a USB soundcard built-into the instrument) and Audacity will work with those. Some MIDI controller keyboards can’t make any sound on their own.
Many keyboard have an analog output (for an amplifier or headphones) plus a USB connection for MIDI-only. You CAN record the analog output with a line-input on a soundcard or audio interface. (The mic input is a bad match.)
MIDI is a different animal - With MIDI you are essentially sending “notes & timing” over the USB bus (or over a regular-old MIDI connection). MIDI files can be very small compared to audio files because any actual sound is generated by virtual instruments (software).
The virtual instruments are rarely exactly the same as the instruments/sounds built-into the keyboard and (as you may know) once you’ve got a MIDI file you can play it back as a piano or a trumpet, or anything else… You can’t do that with audio.

No it’s not. MIDI is machine control. You use a MIDI connection to play something else. Then you can use Audacity to record the music made by _something els_e.
There was a recent poster who wanted to record his MIDI sequence controller. My MIDI music keyboard has a headphone connection and that’s how I record it. This sequencer had no headphone connection. So they were forced to connect the sequencer to a music player and then record the music player.
MIDI is really good at hiding the fact that it’s not music. When you play a MIDI song on your computer, what you’re really doing is playing the computer’s MIDI interpreter software under the direction of the MIDI “song.”
Most of the time it doesn’t make any difference at all, but it can. If you listen to a MIDI piano song on three different computers, you will hear perfect notes, pitch, duration, and attack, delay, etc, but three different pianos. If you use MIDI software like CakeWalk, you can pick a different instrument for your song, everything else stays the same.
What you can do is make your MIDI song play the MIDI software inside the computer and then force Audacity to record “Music Playing on the Computer.”

If your keyboard does have a headphone connection, you can totally record that with a Stereo to USB adapter. That’s how I do it.
Sub your headphone connection for my sound mixer. That’s a good quality Behringer UCA-202 adapter. They are a little hard to come by because of the sickness. Their factory partially shut down.

bei mir wird ein angez importiertes midi morgen k d wm .mid nicht wiedergegeben,
ich kapiere auch nicht, warum kein link zum Verstehen der parameter im manual steckt?
habe das eingeben mit e m-audio keyboard noch nicht versucht,
ich habe 6 7 audio editoren ausprobiert, am weitesten kam ich mit cubase demo aus einer keys zeitschrift.
dort konnte man auf der win98 SE version funktion vieles machen, als aber yamaha
cubase erwarb, war ein support ausgeschlossen, wohl, weil das
erste cubase ST VST ? mehrfach 8x abstürzte pro Tag bei nutzung
einer ISis soundkarte mit breakaot box
etliche editoren wie z B samplitude silver sind nach 4 wochen noch immer kryptisch,
