LC and Midibox link?

Design Concepts
1

The Logic control manual says that a whole midiport is required for each Logic Control, or Contrl XT.

Is this the case for our clones? or can the midibox link be used to put two LC’s on one midiport? Or is there another way?

BTW, this is not so urgent, I still have to build my second LC!

Well the reason I asked that /\ question was because I’m running out of midi ports. So it will either be Midibox link, or connecting one of the LC’s via the midibox to com method.

Anyone got any hints before I embark on this? I’ve read the pages on LTC, and MB to COM, and as far as I can tell, it is just a matter of removing the 6N138, and connecting a MAX232, between the PIC, and the COM port, and installing one of the serial port drivers into windows? (no real need to make the LTC PCB?)

Thorsten, let someone else answer this, this time :wink:

thanks, from Steve :slight_smile:

Alright :wink:

Best Regards, Thorsten.

P.S.: Hint - no, it doesn’t work due to the limitations of the LC protocol

thanks for that ‘Hint’, Thorsten :wink: I thought that may be the case.

Hey Steve

Yup, u could breadbrd the max232 chip between the pic and com port or just use a LTC and leave out the HC00’s. However, I’ve tried the to-com option on my LC (which has 3 cores chained) and I cudnt get logic to behave proper with it :frowning:

Dan,

 thanks for that reply!  and thank-you for saving me from spending time trying to get that to work! So you have 16 channels and one master fader? (re: 3 cores)

…Steve

I wonder if you could create a midi to com interface, by connecting the Max232 to the midimerger project?

Hey Steven_C

If you look at the MIDI information send by a mackic controler or XT, you will see that the fader are

send as Pitchbend on ch. 1 to 9, so each controler need a midi port at your pc and in the sequencer software.

A MIDI merge will not work, sorry.
