MidiBox 808: parallel wiring PIC/LPC cores

MIDIbox SEQ
1

Hi Midiboxers,

i like to put a PIC based core in addition to the LPC17 core in my Seq V4

to be able to “switch” between 808 and SeqV4 mode, depending on which core is powered on.

Would it work if i do a simple parallel wiring between the cores and the “external” parts/modules?

Or could this somehow mess up some connections?

Thanks for any hints

Best regards

This doesn’t sound very easy to me. You would have to switch your DIN and DOUT chains, your LCDs, and your MIDI jacks.

Here’s an idea: pcbatterij has been working on a TR909-style sequencer on the LPC core. Maybe you could get that running on your SEQ v4 hardware?

Hello nebula,

thanks for your fast reply :smile:

But I guess I expressed myself somewhat inaccurate:

I dont want to switch the whole LCD, DIN and DOUT chains, etc. but

connect them to both cores. To the PIC and to the LPC one.

Like a Y-cable connection.

Cheers

Short answer: NO.
