Several questions on LC...

Regard!

I from Russia, on this beg pardon for my bad English

::slight_smile:

Hopes that You my questions not will shown too foolish,

"…I not magician, I only teach…"© (from old russian film a “Cinderella”) 8)

I wants to build MIDIbox LC, but on the strength of determined reasons I can not put (deliver) motofaders, from here questions:

  1. Possible put (deliver) usual faders instead of motofaders, and, if “YES”, must I change a microcode?

  2. What type Jog&Shuttle needed, and as its connect?

  3. I has found GLCD on KS0108 128x64 producer Data Vision Int. Correct it will work with core module in given desksides (I will have one LCD).

  4. Correct will work LC without USB and LTC moduls?

From Russia with love, Viktor

hi viktorG!

ill try and answer the q.s i have a.s for  ;)

if i understand you properly..

  1. non-motorised faders connect to AIN.so no need for MF pcb.s

  2. u want spring-loaded(return-to-center) ? it is possible..find YOUR solution(as TK says..its up to you now)

  3. im fairly sure you can use that GLCD on its own.

  4. again, you are right/

\cheers

To 2: in this case not, the host expects common incremental/decremental events. So, you can use the same rotary encoder like for the V-Pots, but a bigger knob (datawheel) should be prefered

Best Regards, Thorsten.

Hi!

Enourmous thank you for Your answers…

Today has delivered last exam :stuck_out_tongue: and will now occupy LC in thick… 8)
