Anyone has a crossfader for crossfading 4 outlets?

    Hi,
    Anyone has a crossfader for crossfading between 4 outlets, and with the volume distributed evenly?
    Cheers

      haha, that belong to the things on my to do list.
      this is extremly complicated, and there is only one way
      how to start with it: the whole thing needs two modes,
      one which crossfades/crossmixes, and one with crossfading
      turned off so that you can move only one slider.
      why? because only when you can also move only one slider,
      you will be able to set a difference between them.
      but when you do, that also will change the sum/average
      of all 4 - which is needed to do the calculation for
      the crossfade mode...
      i have invested about 3 hours during the last years to
      finish it but it still does not work. if you dont use java
      or make a custom external, you will need tons of "prepend set"
      with different outputs and gates. you will see what i mean
      once you started!
      one more thing: first make one with 2, then with 3, then
      with 4. this way you will find out how the logic has to
      be built for x.

      This is the first thing that came to mind, it works, but I'm not sure if its really what you want, I just noticed you need the volume evenly distributed.
      The 4-pan_2 abstraction that's included was done by somebody else on the forum (can't remember who), I picked it up in a thread about using pictslider to control the pan4s abstraction.
      You might be able to distribute the volume more evenly with this patch by altering the genPan4 subpatch in pan4s. You may have tried this way before with no luck, but here it is anyway.
      Actually I just noticed that there's a bug in the patch somewhere to do with the pictslider input. When the cursor is at the top left corner it cycles through each output really quickly rather than panning smoothly. I'll have a look at it.
      save as 4-pan_2:
      crossfading - I'm pretty sure that pan4s is included with max5:

      here is a simple solution using the great vbap external.

      Nice patch! Although what bothers me about both these patches is that you can't crossfade from 2 to 4 without passing through 3 etc.......I would find that really useful.
      I'm gonna mess around with vbap and see if I can manage to sort that out. See if I can't come up with an abstraction that allows crossfades from any input to any other, with an argument for the number of inputs.

      as for the GUI, you would need to prive two XY sliders, one
      which goes like
      12
      34
      and one which is goes like
      14
      23
      and just connect both to the abstraction your going to build.

      I have this one made using an lcd for mixing the four sources.

      The same patch, fewer objects:
