Three distinct flavors of distortion available simultaneously:
-WRAP performs a modulo operation on the input.
-ROUND performs an integer division operation on the input.
-SPIKE outputs a small trigger whenever a new wrap is generated.
Four voltage controllable parameters each with a dedicated attenuverter or attenuator:
-WRAP controls the harmonic multiplication amount of the wrapping effect, with the maximum wrap range being set by the high/ low switch
-BIAS adds a DC offset to the input signal, allowing a second signal to be mixed in or for the input signal to be clipped.
-FEEDBACK sends the output of the wrap effect back into its input causing self oscillation, ultrasound burps, higher wrap amounts and generally chaotic behavior.
-TRACK makes the wrapping effect follow the signal better or worse, also allowing the output signal to be completely turned off.
Portal utilizes high quality parts throughout:
-Power supply is reverse power protected with high quality TPS7A series voltage regulators reducing any power noise from other modules.
-Entire audio path uses OPA1654 op amps.
-Internal VCAs are Cool Audio SSM2164
