Connection issue keyboard & electric drums

Win 7 64 bit

I have connected my keyboard and electric drums via midi/usb. Commuter has detected them and installed drives and is ready to use. However, in my sound setting only my pc speakers are there. There is nothing for keyboard or drums in sound settings or on Audacity. Please note I only use my PC for normal usage. I have played drums for many years but this is my first solo effort. Please forgive me in advance for lack of PC knowledge/terminology.

Audacity isn’t a MIDI application. You can record the analog output with an appropriate connection.

Some keyboards support both MIDI and digital audio via USB and you can check your user manual.
