The Audio Computer parts from a personal exploration about the music computer which is an utopia that doesn't exist. Many people conformed with how the things are will tell you that if you want to make an audio computer, you just buy good quality computer and then you add the software, a sound card, a controller, etc.. But then we have a bunch of things that conform your own and personal attempt to make the audio computer which will have many disadvantages like the inability to share some specific software due to differences between the hardware (controllers/sound cards), the mess of cables, connectors, adapters, (unportable). Or the massive distraction due to unnecessary software, utilities, screen stuff, etc.. Clearly, an Audio computer should be equipped with a multichannel audio interface, high quality line/mic preamps, integrated hardware controller, midi interface, cv interface. Minimal LCD display for optional performance feedback and DSP chips easily addressable for a flexible hi-quality / low latency audio synthesis/processing. And all this must fit in a portable an efficient package that will allow us for portable setups/recording on the go and optionally a vga/dvi connector for the studio set up when/where we usually create the patches, sessions, sequences, etc that later will be used live.
