converting the old midibox16 to new midibox

[bosone]

while i was working around my new sequencer, i was thinking about the idea of upgrading my old midibox 16 with the old pic to the new MIOS system with pic 18f.

the old midibox 16 is nearly perfectly functional:

I have the "case" already there, with 16 pots, 8 buttons, the LCD, the buttons for navigating thru the LCD and the 4 switch for selecting the different banks.

the "nearly functional" refers to the fact that sometimes i have major jitters with 2 or 3 pots, i.e. they ouput random CC with no apparent reason. if i tweak them a little the problem disappears, but it's becoming annoying. maybe some "cold-solder" contact?

anyway, while looking at the schematcis for upgrading to the mios (core module+din+ain modules) some major questions arose:

1) i have 8 buttons for triggers and 4 for the LCD: can i use them in the same way with the new firmware?

2) the swithces for the bank the bank-change in midibox 16. i don't see anything similar in new midibox MIOS hardware. how can i "multiply" the 16 pots i have in order to have access to all the 128 midi CC? (they work in binary code, so i have access to 16 banks)

is there any use for these switches?

Hi,

the "nearly functional" refers to the fact that sometimes i have major jitters with 2 or 3 pots, i.e. they ouput random CC with no apparent reason.

This is more likely to be noise coming out from dusty/ worn (cheapish, carbon track) pot.. you can try to clean it with contact cleaner from electronics store.

1) i have 8 buttons for triggers and 4 for the LCD: can i use them in the same way with the new firmware?

Yes.

For question number 2:

I think that you can use switches with MIOS (for something), but old limits are gone (using bankstick.. but only one internal bank on MB64) so bank switching concept is changed.

Maybe you want to study bit more about MIOS based version, and change those switches to buttons (and fit some more ;))

Bye, Moebius
