Model 15 App interesting routing trick

[Sawblade Painter]

I recently had a weird idea about splitting pink noise in half, and flipping one of the halves' polarity so they are mirrors of each other, then using the mirrored parts to create hidden noise that can be brought out by varying the reversible attenuators with a control signal. We route like this:

Pink Noise out -> Amplifier 1 in (lower right hand corner of the app)
Amplifier 1 out 1 -> Reversible Attenuator 1 in (set to +8)
Amplifier 1 out 2 -> Reversible Attenuator 2 in (set to -8)
Reversible Attenuator 1 out -> VCO 921A Frequency in 1
Reversible Attenuator 2 out -> VCO 921A Frequency in 2
VCO 921B 1 Rectangular out -> VCA 902 Signal in 1
VCO 921B 2 Rectangular out -> VCA 902 Signal in 2
VCA 902 Signal out 1 -> LPF 904 Signal in
LPF 904 Signal out -> EQ 907A in
EQ 907A out -> Mixer in 1
Output + -> Trunk Line 1
Output - -> Trunk Line 2

Then for pizazz:

VCO 921 Aux out -> Reversible Attenuator 1 Control in
VCO 921 Rectangular out -> Delay Time Control in
Envelope 911 1 output -> VCA Control in

Set VCO 921's Coarse Range to Sub-Audio and frequency to +5, range 8', scale +/- 6 oct. Aux out waveform is fourth from far left. Adjust rectangular width for fun tymez.

Crucially, Amplifier 1 at the bottom right should have its gain set to just above 0. Any farther and things will fall apart because the hidden noise will decohere.

To add a delay before decoherence:

Envelope 911 2 output -> Reversible Attenuator 3 in (the topmost one, next to the mixer)
Reversible Attenuator 3 out -> Reversible Attenuator 2 control (the bottom-most one)

Then set the Envelope's attack to a second or two, and set the topmost attenuator to no more than +1.

This patch creates a dirty sound that after a few seconds turns into an even dirtier one, but still sounds musical and not so grindy if you keep the amplifier (that acts as a gate for the pink noise) at a very low level. By modulating delay time with the LFO then you get weird echoes of the notes that ladder around in the background. Super cool.
