Nord User Forum

Hello everybody, i've a question that make me crazy at all, cause i can't find no answer!
i've search in some olds topic but no one talk about what i'm 'looking for.
I've a nord rack 2x and i want control it (program change filter etc) with my octatrack, here's the problem: I can control al the filter frequency range, (from 0 to 127) and some other parameters i want control but when i try to use the cc's parameter to program change, nothing happen!
When i switch pattern nord lead switch pattern too, i mean, i'm on pattern 4 on the octatrack, and the NL2x too, if i switch to pattern 13, NL2x switch to patter 13 too, but i want to have more control about this, i want decide which pattern of octatrack match with patter of NL, using cc on first parameter pages of the octatrack.
Hope i've explain all trasparent, thank you nord users!

Hej Lelesss!

I guess you need to send both bank & program change ... are you doing that?

EDIT: ... and p128 and forward in the Octatrack manual?

both bank and program change? i don't know what you talking about hehehe
can you explain quickly? thank'z
(i'm pretty sure all the octatrack parameters are ok)

Don't use the CC parameters to change the Programs on the Nord, that's not the right way to do it. Instead, you should send your Program Change and Bank Select messages from the MIDI Tracks in the Pattern.

Look at the Octatrack manual page 114. Here it shows you how to send Program Change and Bank Select messages to the NL2x. If you look at the first diagram, you will see where to put these messages, in the MIDI Note Setup page for a MIDI Track in the Pattern. Put your Program Change number in the box marked "PROG" and the Bank Select message in the box marked "BANK". This will allow you to select any Program or Performance from any Octatrack pattern, which is what you want to do.

So, what is Bank Select? The Programs and Performances in the Lead2x, like most keyboards, are divide into "banks" of Programs or Performances. If you just send Program Change messages, the Lead2x will only change Programs or Performances within the current bank. In order to select a Program or Performance in another bank, you need to send a Bank Select message to change the bank. Note that you need to send *both* the Program Change message and the Bank Select message for this to work. You cannot send just a Bank Select message by itself, nothing will happen. This is just the way MIDI works.

You will have to experiment with sending Bank Select messages to find out which Bank Select number selects which bank on the Lead2x.

If you just want to change Programs or Performances within the current bank, you don't need to send a Bank Select message.

Also, you may need to set the MIDI settings correctly on the Lead2x for all this to work properly. Unfortunately, I don't own one so I can't help you further on this. Try the suggestions above and come and ask again if you are still having problems. Good luck!

I didn't know that it was possible to use cc's to change programs...?

It isn't possible. Bank Select messages are cc's but Program Change is its own message type. I suspect his Octatrack has some default Program Change messages set somewhere.

Whew! For a moment I thought that perhaps the midi spec had changed without telling me...
