No input mixer

May 05 2013 | 6:15 pm


Anyone out there tried to simulate no input mixer behaviour in Max or have any sources they could point me to to explore that?

well, a no-input mixer setup involves analogue circuitry, since that’s your noise source to feed the whole thing.

Some simple noise and a ton of filters, delay and spades of feedback would be a great place to start.
The main thing to look at is separating the emulation of the sound, and the emulation of the mixer interface – remember that they *are* a work-around, and dedicated systems to reproduce those sounds might have a more useful interface.

To get specific, most no-input things start out as just sinewaves, tuned and then faded in and out – at that point we’re close to Berna, really:

Thanks, Wetterberg. I hear what you are saying about the mixer interface not being the best way of manipulating the sound. I will keep in this in mind. Now, by "spades of feedback" are you referring to….using envelopes to attenuate the feedback amount? Or? That Berna thing looks great, by the way. I have been working on some feedback using some delays and a sine wave. I’ll clean it up and post it. I would be curious to see what you would suggest.

I made a max patch around the idea many years ago.

It’s not really possible to do it in max since real digital feedback will eventually crash max (as I found out). So you have to use limiters in the feedback loop, and on the output.

Not to mention you have to use a delay, though now with gen, you can use a delay of 1 sample (instead of one vector as before).

Thanks, Rodrigo. It seems like a pretty fun patch.  Any instructions on how to look into the content, e.g. p feedback core?

The core is just 4 delays, with some control over a short delay time, and limiters in the patch of each.
