02R and HUI "Touch Fader" mode.

So i've managed to successfully get an 02R to emulate a HUI unit (faders only at the moment), along with a Novation Launch Control (with LED feedback) providing the transport controls and fader bank buttons. All with help from the wonderful members of the Bome Forum.

Yay! All good! Except...

When in any DAW I have written some automation, and go back to adjust, using 'Touch' mode, that's when the issue starts. The DAW feeds back info to the motorised fader, which can't be grabbed to overdub automation...

In a proper HUI unit, I have assumed that there must be a small pressure activated microswitch, which enables 'Touch Fader On' when the fader is grabbed, and disables 'Touch Fader Off' when you let go. As the 02R does not have this type of fader, even if you transmit 'Touch Fader' messages as part of the fader movement, the faders still fight back, as they are being constantly updated by the DAW, and seem to ignore the 'Touch Fader' HUI messages...

I thought about this, and have implemented a momentary button on my Launch Control, which temporarily disables the feedback to the faders (whilst held down) enabling you to 'touch write' automation. It's a crude but effective solution to the issue.

Has anyone else got a more elegant, or automatic solution to this issue, or am I missing something in my MTP project?

 

Thanks for reading!

 

Andy.

Maybe place a timer on the fader value change. Have a translator that disables input back from the DAW (or perhaps not send any message to the DAW)  while being moved.

When you stop moving the fader (after some preset amount as set by the timer). Have the timer fire of another action to re-enable feedback.

Edit: Not a tested solution, just a possible idea.

Hi Steve!

Thanks for the reply. I’ll test that suggestion, as my timer is working slightly different from what you suggest…
