I came up with this idea some years ago back when I was searching for a decent sampler/midi sequencer/composer.
Building a whole setup with laptop, midi controller, soundcard, usb cables, etc.. seemed very laborious and time consuming to me so I started wondering why do I still need a laptop for using ableton. It would be nice If I had one solid unit with a touch display, rotary buttons, faders, push buttons but also audio ins/outs,midi in/out. The MPC came pretty close to what I was searching for but I found its user interface pretty outdated and time consuming also my mpc1000 is very limited when it comes to looping, visual feedback on pads and it has no synthesizer built in for example.
So my idea was to build an interface which has all the ableton synths, fx, samples, sequencer etc.. like Ableton in a (real) box or something like that.
I still have some drawings I made for this concept.
