VCV Free – Detuned Panning Wind Chimes

An experiment using only VCV Free modules that demonstrates panning via detuned oscillators. The effect is somewhat subtle, and requires good stereo output.

Each chime ring consists primarily of two slightly detuned pitches. Both sine on the left, and one sine and one cosine (inverted sine) on the right. The detuned pitches go in and out of phase with constructive and destructive interference causing volume to swell and fade. Because the sine and cosine are 90 degrees out of phase, the left and right alternate as to which side is sounding and which is silent, giving a panning effect.

In addition to the primary pitch, each chime also has a very short duration inharmonic strike consisting of two additional triangle pitches.

So that makes a total of 4 frequencies per chime, times 6 chimes for the upper octave, and 6 for the lower octave. The grand total is 48 frequencies produced by 4 polyphonic VCOs.

A 12 channel polyphonic LFO clocks a RND to generate 12 random voltages to drive chime triggers. A COMPARE fires a trigger for each chime when the voltage is greater than 9.9 (1% of clock triggers on average). Each chime trigger also triggers a 2nd RND to determine random intensity for each strike.
