Hello all,

I'm trying to write a patch that begins an effect every time the adc~ input registers a new note. The only way I can figure out to do that is by seeing if there is an increase in sound volume of the input (this would work for all acoustic instruments that would be fed into [adc~]. Essentially, I would be very happy with [change] if [change] would only trigger when there was an increase.

I'm trying to use a table to read the previous value then after the comparison write to the table, so it can be read again, but I can't get that to work.

Any suggestions?

@aelmore Try this as a starting point........ sigmund_change.pd..... it will write the note values (midi notes) to an array.

Or if you really want to trigger by volume level (and not frequency) you should work your way through this thread......
http://forum.pdpatchrepo.info/topic/10539/audio-triggering-samples-with-env .....replacing the playing of the wav file with the triggering of your effect.
It has some patches using [threshold~] which you will find useful.

@whale-av Thank you for your help! You've unblocked me.

I will begin using the note value solution for now to get my patch functional. I'll post my solution to the volume level trigger when I get around to that bit.
