You get one Square module with three simultaneous outputs.
You get one Saw module with three simultaneous outputs.
You get one Sine module with three simultaneous outputs.
Add them up and that makes nine simultaneous outputs which you can patch any way you like, because it’s a full modular system.
The Behringer Neutron, for example, is a semi-modular. There are two Oscs with various waveforms, but only one audio output per oscillator is available for patching at a time. It is what it is, but for some people it may be the right choice for them.
The 400 sells for $500 and contains 14 modules, which averages to a whopping $35.7 per module. Oh, it also includes a sturdy sheet metal enclosure, patch cables, etc. and can run on batteries.
