Hi, theres a vst called Glitch and it has a Overall Probability and Passthrough controls and i was wondering how could i add probability to an event so if i set the control at a high setting it would have more chance of happening and if it was set to a low setting then the event may not happen. Has anyone got any ideas on how you could make something like this for green data in SM?

Create a module with 2 ins and 2 outs, the two ins are a 'do' trigger and a 'probability' float. The two outs are 'true' and 'false' triggers.

Connect the do trigger to a pseudo random number generator, there are a couple about the forum, make sure the output is between 0 and 1. Connect the output of this and the probability to a 'less than' module, so if the random number is less than the probability the output is true.

Make two connections from the compare module, one to a BSwitchTrig and the other to a 'not' then a BSwitchTrig.

Now two connections from the 'Do' trigger, first to the first BST then to 'true' and another to the second BST then to false..

With a trigger input you should get either a true or a false trigger output depending on the prob..

If you use multiple instances of the module, you'll need to set the seed to random in order to avoid repeating patterns..

Hope this helps
