  Analog Control Elements

With MIDIbox SID V2, analog control elements like pots, faders and joysticks are natively supported. Everything you can find in the forum about such an extension for V1 is obsolete, especially because a dedicated driver is used instead of MIOS_AIN for optimized performance.

This feature has to be explicitely enabled within the setup_*.asm file by setting DEFAULT_J5_FUNCTION to 1 - once you did this, all unusued analog inputs must be clamped to ground in order to prevent random values! This is especially required for the slave modules, when the master firmware will be transfered to the slaves via ECAN (clone feature).

All 8 analog inputs are sampled with a frequency of 125 Hz. Multiplexing (-> MBHP_AIN module) is *not* supported! So, 8 inputs are maximum.

The firmware currently only uses the first 5 inputs of J5, the remaining 3 are reserved for future features.

The converted values are forwarded to the knob handler. This generic approach gives you all advantages of the knob concept: value changes can be forwarded to two sound parameters, a Min/Max range can be specified, and the converted values are also available as modulation source!

You've got 8 analog inputs.

You can do whatever your coding skills are capable of.

I have never coded anything in my life (except a website...)

Does anyone have an example of the code that would tell one of the inputs to be used to control cutoff or resonance?

You simply have to enable the Analog Inputs. (All the information on how to do this is online. The only thing you have to do, is to do a minor change in the source code and recompile it, so that in the end you've got a new hex file you can upload.)

The rest, like assigning the knobs to specific parameters, can be done in the menu of your MB_SID (KNoB-Menu, search the manual for that.).
