Midi Feedback Loops with BCF2000

Midi Feedback Loops with BCF2000

(or any other motorized control surface for that matter)

Hi

I gave up on this a while ago after much frustration, but with my slightly increased knowledge of Max I decided to give this another go, but can’t seem to deal with it!

What I want is a parameter that can be changed by the controller, and in return if that parameter is edited with the mouse, for it to return the data to the controller WITHOUT accepting the controller’s immediate response to this. (i.e the feedback)

I’ve tried with trigger (maybe I’m doing this wrong), and I’ve looked at some other patches but they only seem to recall banks of data.

Thanks for any feedback (or not – crap pun i know!)

Something like this?

Probably not, as this would mean, that you’d have to mouse-click or
bang the slider if you wanted the changes you make on the external
controller to have any effects on what you’re doing…

Hi,

With the BCF2000 (with last firmware) i have no feeback problem.
So i do it without the [prepend set] and it works pretty well!!

You have to break the feedback loop just for the UI part:

If you want functionality also without the BFC attached, use the second
version.

As the controller feeds back its input, you just need to connect the
output of [ctlin 77] to whatever you want to control. The downside is
that if you don’t plug your MIDI device, you can’t use the mouse to set
the value anymore. But I just see Stefan already posted a solution for
that :-)

Not necessarily – if you connect _both_ the output of the “ctlin” and
the out put of the fader to whatever does the work, then changing
either will have the same effect.

Thank you all for your very helpful responses. I’ll have a go and report back on how I get on

How stupid I am! Was just trying some stuff out thanks to your replies, and stumbled across standalone mode 4 on the BCF2000 which outputs incoming midi data from the other midi output. Voila!

Cheers for the help!
