dude, midi has come a long way since midi keyboards. a quick search for triggerfingers will show you a cracking bit of gear. and at only £100 it's hard for any young/new music producer to miss.
Not really what I want. I'm not interested in laying down beats- and I play keyboard so the best way I know to get notes into a sequencing program is via the keyboard interface.
That machine you linked to just now though- you should be able to easily make a virtual touchscreen version of that, suitable for tablets. I'm just trying to cut down on gear/junk. If you could get a serviceable touchscreen keyboard controller (with a practical emphasis on 'serviceable', and a drumpad type thing- and your control surfaces, etc... that would be very neat.
Ah right, no I agree a touchscreen MIDI keyboard would be useless, but as a control surface for showing a channel strip(s) or effect params or something or even as a controller like a Kaoss pad there are a bunch of ways a multi-touch tablet could be useful in a compact studio.
No, because it's not velocity/pressure sensitive. With real samplers/drum machines/electric drum kits, the volume (and possibly other parameters) of the sound is different based on the velocity of your finger hitting the pad.
