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

no-input-mixer

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.

I do sorry for replying for a post 8 years ago but -

Is your patch of the no input mixer is still available somewhere to experiment with ?

I just tried to open it and it wasn't recognized by Max, but I don't have any older Maxes installed on my system right now. I believe this is the (super old, and super messy) patch.

Thank you very much Rodrigo! I will look into that

Old max patches on Mac needed no file extension.

If you add .mxb to file name, max 8 would read the patch.

except for the extras menu, then you need to convert to json first.
