Problems writing the correct path for controlling reverb effect parameter..

I am having difficulty getting the path right so that I can control the Effect Mix parameter by setting its value from an integer received from some data from the camera. See below:

Can anyone put me on the correct path (pun intended heh heh)

I suggest you go over the Live API reference page again because it seems that you got quite a few details wrong.

For starters; you access devices the same way you access tracks. Why would you use "tracks 0" and then also try "devices Reverb-Wide Ambience…." ?

‘live_set tracks n devices n chains n’ where n is a number from 0 to x which corresponds with the number of the track or device or… yet starting at 0 (the first track is tracks 0, the first device is devices 0, and so on).

Most of all; you cannot use names in a Live path.

I suggest trying the LOM.Navigator. Its a M4L patch which allows you to "travel" the Live Object Model where it will also display the correct path at the bottom of the patch.

Speaking of which… Some time ago I blogged about the LOM; an article some people found helpful. May give you a good heads up as well…

Okay I see where I was going wrong there..complete schoolboy error on my part, I was shattered and obviously wasnt thinking properly. Thanks very much for the navigator too!

So, I now have: live_set tracks 0 devices 0 chains 0 parameters 8

But, Im still not getting the thing to respond to the float its receiving. I have modified the Live Tempo Automator v1.0 patch to ramp the value of Dry/Wet of Effect Mix parameter but there is something I keep missing in the patching.

Please see below and advise..

Too many possibilities to determine a cause here..

Start by checking the Max window (and optionally Max runtime window (right click on a patch titlebar and select "show max window")) to see if you can spot any error messages.

Also; you are using a rack of some sort (instrument, audio effect, …), right ?
