for learning more about sound lib MINIM
( @GoToLoop NO, the question is not about the library )
i play with sound synth, using these “natural frequencies”
you can hear about in esoteric / meditation videos… but also when you
dig about the MALTA Hypogeum and its sonic resonance
but personally, i like the interpretation here:
Have fun, create and experiment, and don’t let standards hold you back!
now in that kind of meditation/healing videos like this
you hear not only one tone, but also not like a melody?
( sorry long intro )
question:
am i supposed to play several of that tones/frequencies at the same time or only ONE and find some fitting chords for the actual one?
my start code:
// taken from MINIM examples:
/* how to patch more than one UGen to a Summer. AM*/
/* frequencyModulation FM */
/* how to use an FFT to analyze */
// natural frequencies ?

someone play this already?
