Analog modeling synthesizers simulate the behavior of the original electronic circuitry in order to digitally replicate their tone.
This means that many of them, especially the more modern models, can produce as many polyphonic voices as the CPU on which they run can handle.
Modeling synths also provide patch storage capabilities and MIDI support not found on most true analog instruments.
