I ran across some stuff on the internet about 528 Hz and other solfeggio tones.  Is it just New Age mumbo-jumbo? Who knows?  I made a patch using one MOTM-300 VCO and the Teezer VCO both set close to 528 Hz.  I let them be a little off.  Nothing is perfect, so why try to be?  I ran the sawtooth outputs of each VCO through a channel of the Cynthia Waveform Animator and then through a half of my dual MOTM-480 VCF.  I also mixed pulse waves from each VCO into each respective MOTM-480 channel.  (I got a pulse wave from the Teezer using my Mixer-Comparator.)  I put very slow sine wave LFOs on each 480 FM.  Then I added a bass voice by dividing the Teezer output by 16 with the MOTM-730 pulse divider to get a 33 Hz square wave.  This was run through a MOTM-440 VCF, which had another very slow LFO on its FM.  That was the basic patch.

A few days later I was working on a ring modulation patch for the Mattson VCA.  For that I used a second MOTM-300 VCO and the Morphing Terrarium VCO.  I utilized the J. Haible Trapezoid VCA to envelope the MT sine wave going into the Mod input of the VCA.  A MOTM-800 drove the CV input of the VCA.   I fiddled with the frequency pots of the oscillators to get a nice bell tone.

Now it gets eerie.  Both patches were running.  I had the 528 Hz experiment turned off in the mix.  I just thought, hey, why not mix the two.  Probably be very dissonant.  No!  It was very harmonious!  I checked the frequencies and without intending to I had set the MOTM-300 to 262 Hz (about 528/2) and the M.T. to 528!  How did that happen?  Must be the mysteries of the universe.
