Hello,
i want to control my little old korg m3r by my vmb64/mb64
The sysex bytes which are neccessary to change the programm parameters are described very well in the manual. But I’ve no idea how to make my mb64 send these metaevents. I think it’s not very difficult but i just don’t know how to manage it. So perhaps you can help me with this problem. :-/
Hi,
there are some examples in mb64_meta.inc
But the virtual midibox doesn’t support meta events, so you have to build a real one, first
Best Regards, Thorsten.
Hi,
o.k., I’ve built my mb64 :)
and now?
How can I create my own Metaevents?
Alright, now the fun begins 
Did you take a look into mb64_meta.inc? Then you could change the SysEx example for AN1x for your M3r and try it out.
Best Regards, Thorsten.
o.k.
I took a look into mb64_meta.inc.
My Problem: I’ve build an “old” midibox without MIOS. :-/
So, I have to buy a new F18 PIC and modify my mb for MIOS?
Well, this is something which you haven’t mentioned before. Yes, it makes always sense to upgrade the box to MIOS. Just order some free samples at the Microchip homepage and exchange the crystal - it costs you maybe 2 EUR, but brings you a lot of additional features 
Best Regards, Thorsten.
One last question before I replace the PIC: Is it possible to change the metaevents by changing the Sourcecode of the Pic16? Would that work? An if the answer is ‘yes’:
which editor do I need?
Yes, this is also possible, but more difficult because of the PIC16F quirks (banking, paging) and the very limited memory (I guess 50 bytes are free…
I just sent you the firmware via email, meta.inc has to be edited with a common text editor and it has to be assembled with MPLAB V5.xx from the Microchip page
Best Regards, Thorsten.
