Re: Recording Electronic Drums
The way I record audio is using the Quick Recording function of my Roland. Not sure all kits have it but I assume most of them do.
1) Record the drums into your module using the quick rec function
2) Connect the module to your computer using the headphones jack of the module as "out" signal and the mic jack of your computer as "in" signal.
3) Press record in your software and the quick play button in your module
4) Mix the original track with your drum track and adjust the volume levels.
I find this very simple and the recording is done in great quality but of course will only work if your kit has that rec/play function.
Audio recording is faster but it's almost impossible to edit. MIDI is more complex and time consuming but you're able to edit the recording.
For your purposes I think audio recording is the way to go.
