Some thoughts about my plan

[OneLittleFonzie]

So my plan is to make a sort of Midibox 64 with Core32 bit a bit bigger. First I want to make a Jupiter 8V and a Prophet 5V controller with one midibox 64x. The next project will be a controller for the Arturia Moog Modular V.

The first one I can make with the supported 64 analog inputs and the 128 binary inputs. I'm already going to use NRPN messages.

For the modular I would need more inputs.

So, I'm considering using lines for the multiplexer for analog inputs. I'm surprised this is not standard as you would double the number. Is there something I don't know? If there is a reason not to do so I would like to hear that.

For the multi position switches I was thinking about using analog inputs and a few resistors with the switch to get like 3 postions. Or would it be "cheaper" to use 2 binary lines?

I'm really existed about this :-)

I've made a controller for the JV1080 10 years ago; Only using I2C. 128 pots :-)
