YYS is a super useful spin on the 4x2 matrix mixer. Instead of comparatively boring unipolar attenuators to send to the destination channels, attenuverters were used. This allows combinations of DC signals that can cancel each other out to make interesting new waveforms, and with audio signals can cause strange stereo cancellations. dsp.coffee also included inverted outputs and bipolar LEDs as a bonus.

Features:
- 4 inputs with 2 attenuverters to send to output A or B
- Inverted outputs that follow A / B
- Bipolar LEDs for monitoring
