module to switch between two inputs without trigger by probability

Plugins & Modules
1

hi to all,

I need a module that can switch between two inputs to one output without a trigger, only by a probability knob.

Until now, I cannot find one.

Any ideas?

Is there a reason why it has to be in one module? There are plenty of switches and plenty of random generators with probability parameters.

yes simple reason is to save space.

I haven’t reda the documentation, but doesn’t the Venom Bernoulli Switch do that (if you use only one of the two outputs)?

5

The documentation says that a trigger is needed.

and without it, it does not work.

Hi Karl

lets say you put in one sine and one square wave to A and B and set the probability to 30 % what do you expect to happen and when ?

EDIT : Oh I think I know what you want , you want the probability to choose the A or B, so zero will be 100% A and 100 will be 100% B , you want to choose with the probability knob.

yes exactly that.

to switch a CV from time to time, a to v.

not mixing.

8

From what time to what other time, something has to create a rate in general and usually that’s a gate or trigger

I do not fully understand what you want. A switch always needs a trigger, either via cv or manually… it defines when to switch.

I do not think there is a module that automatically fires a trigger when turning a probability ratio: that would require an internal slope detector with a rather slow response/slew that only commits to a switch when not turning. This will never be exact.

i have two CV inputs, exactly pitch voltages.

now I want to fetch some pitch from a and sometimes from b. this will be the final pitch to play. a knob for the probability to fetch from a or b selects it.

i got it working with clock or phasor. but I wonder if it will be possible only with a probability knob.

pick any 2:

  • control “sometimes”
  • control probility
  • use only one module

If you choose not to control probability, this might be a useful module with the Pinning knob all the way up and mode set to Free:

You want the knob to say when to switch. But how will this knob “know” when to switch? My guess is only when you have reached the desired value. A knob gives a continuous/stepped signal, not an endpoint. Only if it is not turned, it “knows” and is able to fire a commit.

Your main reason is to save space. A trigger module does not take a lot of space at all, the construction with a slope detector only adds

14

Actually you could do a very crude “control” of probability with that module by patching the 8 inputs as AAAABBBB for a 50% chance or AAAAAAAB for a 87.5% chance of A.

Not to hijack but this reminded me of this nice technique:

Bernouli is one in to two out, he’s looking for the other way

17

Normally yes, but the Venom Bernoulli switch I brought up is 2 in, 2 out and if using only one output is 2 in, 1 out. But as Karl said it requires a trigger and that is not what he wants.

oh, I will check that module. i think it will do what I want.

thank you.

hello, i tried the module, but i am not able to set it to input a only and input b only. it seems to mix always. not what i want. any ideas?

Well, yes, it does seem that the Pinning knob does not do what the manual suggests or what you would hope it does.
