Filtering/converting just some CC messages?

Hi there - newbie here so please be gentle!

I'm in the process of re-purposing a Steinberg CC121 controller. Along with a bunch of buttons and controls it has 12 dedicated knobs which are hardwired to Cubase's EQ controls. I want to repurpose those knobs to control other parameters, and I've succesfully done this - capturing the ouput from CC121 and ouputting converted values to Bome virtual port.

What I want to do now is allow all other CC121 MIDI data to merge with these translations, just blocking and converting the repurposed controls. I'm sure I'm being slow but I can't find an easy way to do this. If I connect the CC121 out to Bome In on the router it ignores my previously set up rules.

Please help!


I assume you put in a MIDI Thru path for all the controls you want to pass through.

My guess is that your CC translators are properly modifying the incoming message but since a thru path is set, the original message is still getting through even though you have "swallow" set.

The thing about swallow is it only works if the outgoing action executes so if you have something in rules like

if xx=yy then exit rules, skip outgoing action

In the above exampe, since the outgoing action is not triggered the original message will still pass through even if swallow is set.

To solve this, add a translator with the same incoming action that you do not want to pass through and then an outgoing action of NONE.

If this doesn't make sense, please post your project file, and I will be happy to show you.

In summary, swallow only works if the outgoing action is triggered (even if the action is none).

Hi Steve,

Thanks for your reply - it was me just being a klutz with the thru routing and getting ins and outs the wrong way round.

Anyways, project succesful - encoders (along with coding accelerated inc dec) and buttons repurposed, leaving the rest of the unit functioning as before. I'm absolutely delighted - MTP is the total shiznit!

Glad I could be of help!
