This is my polyphonic setup with 6 Waldorf Pulses. It becomes a massive synth. It's almost like a Memorymoog with 3 oscillators per voice and 24db filter... "almost". You can also do different setups. Say you layer 2 Pulses for a 3 voice with combined patches. You have 6 arpeggiators at your disposal. with different clocks, octaves, sounds. The only downside is the space it takes to have it.
