Pure Data has strong community spread over varous listservs, fora sites and fb groups. One hotspot is the pdpatchrepo and there i found this “lavalamp” Patch. This inspired me to create a simple sine machine. It evolves with the ‘lavalamp’ gaining the oscilators while another oscilator modulates the spacing between the frequence of the sines. This creates continuesly rising amd falling harmonics that go in and out of tune.
