I tried to make my own Electro Harmonix MOD REX pedal by using different plugins for each block. I experimented a little on the order of the plugins. I am blending three square waves each tuned to a different octave of "A" to give the originating sound a little more depth. I start with the blended tone and then switch to the chain with the plugins emulating the EHX pedal. These plugins do not clock to the master BPM and I hope they get updated to do so.
