I have the MTP 2 quad as a play around controller at home and I love everything about it!
The jogwheels are small but big enough to scratch, the pads for easy autoloop, loop in/out, set up to 4 hot cue’s(!), only downside is the effects (maybe just me).
But! the pitch isn’t inaccurate… (atleast not with vdj)
But I have never tried the RMX2 so I can’t give you an opinion on that… But if you’d ask me I’d say MTP 2 no doubt!
