Hi, is there an external device u can buy that let you control the drum machine that is included in the djay-app? As far as I can understand I can’t remote control the app’s drum machine from my Mixon 4 console? Is that correct- and is there a device/ console u can buy for the drum machine? (I’m talking about the preprogrammed drum machine that features Deep house-drum sound, Hip-hop, etc… Help please!!
