I'm working on a patch that need to randomly mix four (currently) sources of audio into four audio channels. Mathematically I think the problem is how to choose a group of random numbers with a particular sum (

My current solution is basically a cludge that reduces the random range after the first channel and then makes sure that the random number chosen (which reflects the amount of the audio source in the channel) is never more than 1/3 of the source. This has many problems, particularly if the first random number is very low.

Can anyone suggest a different way of going about this task. I wonder if there is a simpler way to mix the audio (perhaps randomly mixes the signals regardless and then reduce the amplitude until it's below 0db?) or simply throw and sum, throw and sum until it's correct?

I've added the patcher that is doing the distribution.

Wow that works very well and is quite elegant! My most recent attempt throws randoms replacing the highest number in a list until the sum is =
