Forgive me if this is a newby question but I am new to PD.

I really need a master volume pedal to control my [output~] object.
I added a midi [ctlin] for an attached foot pedal but it is not working.

It changes the slider on the output object but does not actually
affect volume. I used autoscale to get the values into the
0-1 range which seemed to work fine.

The slider moved but no output change. It seemed to zero
out all output and break the [output~] object.
(I am using the output~ version which has the slider and DSP
mute included)

I have tried opening up the [object~] and attaching the
[ctlin] to various inputs within the patch but am not getting
anywhere fast!

Thanks for any assistance.
Is there is another object or way to approach having a midi
pedal controlling the final volume?
I would appreciate any advice!

I have attached one attempt to make this work..

Thanks very much

This is a weird one. The reason why is because the [hslider]s send and receive name are the same. This seems to have the effect of setting the value instead of setting and outputting. So just change the name of one of those in the properties window.

Also, instead of [autoscale], I think it would make more sense to just use [/ 127].

thanks so much for your help! I changed the names of the hslider send and receive symbols and now the [ctlin] affects the actual volume!

I also used the [/ 127] which is very nice- thanks for that. I have developed another odd issue however which is that the slider(and volume now) move opposite what I would expect. When the midi sends 127 the volume goes to 0 and vice versa. Is there a simple way to flip this? I think there is something basic I am not remembering perhaps.
It is excellent to have midi control over [output~] ! Very cool.

That doesn't make much sense to me. Are you sure it's actually sending 127, or do just expect it too? Try sending the output of [/ 127] through [expr 1-$f1] and see if that helps.

You are so right. It is my controller doing something odd.
I am using an X-Session to get this going while I am traveling
away from my midi pedal system.

The slider is sending opposite numbers than it appears to send
on the controller itself......pretty weird for sure. PD logs it
as running 127 to 0 rather than the other way around.

Everything else seems OK so I am not going to worry too much.
Thank you so much for your help with all this!

I hope to have an performance Saturday using PD and Oboe and some other hopefully interesting things.

It's great to have the master volume pedal to [output~] option.
I was not going to figure that out on my own for sure !
Thanks again!
