White noise hats

Yes already in my demo video, the sound is not very good (old camera :slight_smile: ), maybe rather listen in my “modular track” playlist (not in the 1st part it’s a bit old now) for a better sound recording.
But otherwise it is a very very simple module and it would surely require some modifications to be able to also adjust the frequency, but it do the job

There’s also the CMOS noise bell, very versatile

and maybe some idea here too
