128 Analog inputs

MIDIbox HUIs
1

Hi Forum,

i was searching for about 2 hours now, i cant find the answer.

i want to midify an old audiomixer, which has 128 analog, and 96 digital buttons/pots/faders

is it possible to connect 128 analog inputs ? i dont understand that core slave stuff. is it possible to connect 2xAINX to one core, 2xAINX to another core, and then connect the 2 cores? if this will result in 2 different midi outputs, or is it one ?

i read about the midibox NG, wich allows connection of 128 analog inputs, but i cant find it anywhere. is it dead ?

thanks in advance

Hi zeh,

these are some good questions:

  • I found the answer in the C function-listing:

up to 64 pots can be connected via AIN multiplexers

So only two AIN-modules can be connected to one Core.

basically, the two cores are interconnected and the midi stream gets “tunneled” so you only have one MIDI I/O. The downside of it is that I doubt linking is supported by any prewritten MB Midi-Controller application (like MB64/E), so you’d have to program your own app. But the linking-features are nearly all handled by MIOS, so if you got some minimal experience in programming, it shouldn’t be a big problem…

You may want to take a look at the function listing to get an impression:

As you could use the source of the “ain64_din128_dout128” application as starting point, I think it’s a manageable task :slight_smile:

See C-Applications on bottom of the download page.

  • and I can’t find anything about the NG, too. sorry  :-\

hope this helps a bit :wink:

best regards,

Michael

of course, this helps. its time to start coding mios stuff i think. i have managed to never code any line of mios code until now :slight_smile: but i think the time has come. i will try it. many posts will follow :slight_smile: but i will build the hardware stuff first.

thanks!

The only time I found references to the MIDIbox NG it was used also referred to as the LC, could the two be the same? I can’t find any references to how many AINs the LC can handle when you’re not using motorfaders, at least in the time I have available at work while my boss is out of the office…

I can’t find any references to how many AINs the LC can handle when you’re not using motorfaders

Furthermore: I also can’t find anything that even a single AIN is supportet in the LC.

I think AIN was never the intention of the LC.

Watch out though - the pots in the mixing desk are likely to be logarythmic taper, and MIOS requires linear taper.

What’s the desk?

One workaround would be to let the two cores work independantly and connect them via Midi.

I actgually pulled an old Spirit Folio apart last night for the same purpose. Never occured to me about the logarithmic taper ???

Any workaround?
