sounds like you have a plan ,, got a low level tablet free thru phone company ,,already had U-Mix Control pro2 ,, figured to set up a small mobile ri for fun ,,issues getting MIDI connection because of tab ,, so
best laid plans ,, the app for tab is realitvly in expensive ,,the software for laptop is also ,,unless you want to expand to full vid features /hid control/DVS /timecode control ,then Cross DJ will work ,, you can down load the free version ,,(no MIDI control) for software familization ,or the demo for time restraint usage ,
so any other
feel free to ask ,, use the search function in fourm for more topics related to what you are trying to figure out ,,good resource
welcome to mixvibes
if you purches the versions for computer/laptop ,,please regerster the software licence key in the forum ,,will save grief later
