if signal is greater then threshold close gate~ for period of time -> ?
Hey!
I've got simple problem but I can not find a simple answer.
I would like to make a patch which do this simple operation
each time an audio singal is greater then threshold close gate for 100 ms
It's not a big deal to make it like this
[>= threshold] - [gate~] - [edge~] - and bang from edge~ closes gate~
simple.
but how to solve the problem and stay in signal domain?
Thanks!

Not exactly what you asked for, but here's a useful "ducker~" abstraction I keep on hand, for suppressing signals below a specified threshold. I think you could use
This does what you want
Thank you very much John!
Hey guys, I've got one more question
cause I've got that feeling that I am missing something.
sah~ is ok if you want to sync your signal to other one with freq of control signal
but what if you wont to sync it to the event not to freq of control signal
or even worse - you want to mix those to approaches
for example you can send "clear" msg to dealy~ (John's example) but once again you are going out from dsp chain to shake hand with scheduler
so how to managed complicated logical msp systems which do not produce sound at all - only transitions from 0 to 1 to 0 and so on
have got any examples, tutorials, advices?
or maybe it is time to dive in gen~?
thanks once again!
OK, I won't ask why you want "to manage complicated logical msp systems which do not produce sound at all." :)
As you no doubt know, the logical operators such as >~, ==~, etc. generate 0 or 1 based on their input values. The delta~ and change~ objects are also good for observing what happens in a signal. And sah~ is good for sustaining an instantaneous sample value. phasor~ and count~ are good for cyclical/periodic recurrences at a specific interval of time, and delay~ allows you to offset a signal by a precise amount of time.
So it's all just a matter of imaginatively combining those to do whatever task you're trying to do. Here's a patch that demonstrates a few tricks, and also shows a solution to your original question.
(Oh, and yes, gen~ can be quite handy for this kind of stuff.)
Great examples Christopher! Cheers,
you can control gate~ with line~ or index~ /~
