The whole page flickers in Firefox on the PC. I think it's the images as that flickers in the feed too.

I bought the interface that would give me more options. I've not used the MIDI, but that is something I want to explore. A lot of devices use USB now anyway. I could set up multiple drum mics, but I have the Yamaha EAD10 that records the whole kit. That also does USB audio. My Roland e-kit does audio and MIDI over USB. I've really got all the gear I need to make music.
