Sound Character and Original Hardware Behavior
Model 72 is based on a monophonic synthesizer from the early 1970s. Softube says the software components were measured and matched to a hardware unit, so the instrument keeps its non-linear behavior rather than an idealized version of the sound.
One hardware trick is reproduced: routing the high-gain output back into the external input creates a raw feedback tone. Softube added this behavior to the Model 72 Instrument plug-in, so it can be used directly without external patching.
