Anyone know anything about Roland's short lived Digital Control Bus ? As found on the Juno 60. Has anyone done any work on interfacing the midibox to this standard?

Hi.

You can find the DCB specs from:

Massive bump..

Could this be a job for midibox? I guess more info on the communication protocol would be in order eh?
I'd be interested... maybe Sasha would too with his Juno 60 refurb.

I've got a stupid amount of DCB connectors too, for anyone who is interested.

Regards

Had a quick look at the specs... seems like a pair of unidirectional serial busses... If I were doing this, I'd be making the DCB-facing hardware a small PIC, and use it as IIC_MIDI, so the whole DCB thing would be transparent to the midibox core.

UP!

Dear Midiboxer,

I tried to send "DCB string" (keycode 0xfe,data 0xa4 note on C2, 0xff end of the string) trough MIDI out in my JUNO60.
Like DCB protocole is 31250 hz communication ( same as MIDI BAUDrate ) i hoped that my Juno 60 played some note, but nothing happend.
I believe that the clock signal have to be send too, i'm right?

I reed this Wikipedia article about DCB protocole here
and i dont understand what's the "Busy Data"

Is there aénybody how could explain how interfacing DCB protocole with MIOS8 core

Thank you
