Starting on the redesign of the instrument. The integration with the huge soundcard was not viable and there would be (audio) cables connecting them anyway, so I decided to just integrate the filters and the raspberry together.

I also added a touchscreen and i'm still deciding what buttons, sliders and knobs to use. 

Will focus on the main functionality first, audio routing, spatialisation and analogue filter control, using external midi controllers for key/knob input.

The analog modules could maybe be stacked and the input/output connectors would line up nicely as left/right input/output. But it would become quite fat:)

Here are some of the examples of hookuppable controllers. Yes even a joystick:>

Now let's get coding:)  I will use JACK as the sound driver, the wonderful linux stack will take care of the drivers for all connected soundcards and my own C++ based synth/router/mixer.
