Re: Recording my Yamaha dtx500 - how?
Wow - where to start?
First of all, midi is not audio. You use the midi out to connect to an external device like a computer or another module to trigger sounds from those.
To record audio, you use the audio out jacks. If you're using a computer, you need an audio interface. Connect cables from the audio out jacks to the interface, select the interface in the recording program, set levels, and record enable the tracks you want to use.
But first and foremost - read the manuals.
Then do some research on audio interfaces, and the rest of everything involved. It's not easy starting at the beginning, but that's where everyone starts.
