A very simple (stereo) subtractive low pass filter patch. Using 2 oscillators. Macro’s available are for the oscillator shape (moving towards saw), the filter cutoff and reverb mix.
I have started to include formula’s to introduce a slight stereo off-set between the left and right channels (formula’s B and C).
Formula F is used to bring in the reverb (see also the EaganMatrix cookbook page 35: Recirculator Offsets (Reverb/Delay).

As I do not understand half of what is described in the Eaganmatrix manual, but I want to prove with these patches that experimentation and trial and error actually are good ways in exploring the Eaganmatrix.
This patch doesn’t come close to the quality of the sound of an analog synthesizer but it demonstrates the simple filter and ability to run different settings in the left and right channels.
