I'm looking to get a Through Zero Oscillator (actually I think I need three for the thing I have in mind). Have seen demo's on YouTube for the Zeroscillator and while it is amazing it is just too much money. I'm in Eurorack Format and I've been looking at the Cyclebox and Rubicon. Are there any others that I should be looking at? What do people think of the Cyclebox and Rubicon? My understanding is that the Cyclebox would FM itself internally which would free my other oscillators for other things which would be good. I'm mainly thinking of bell-like sounds for the thing I have in mind. But with both of these options there would obviously be many other applications.
