The reason I suggested a used one is because you could get close to what you paid for it back if you want an alternative. Having Audulus available to your eurorack will allow you to explore various types of synthesis and use different tools in a pinch. I really like the idea of being able to use a rack on its own without the need for Audulus. But I also like being able to use Audulus for signal processing and a zillion other applications. Often I’ll see a digital oscillator or something coming out but then I just turn to Audulus. I mean you could have a polyphonic digital synth and all else that goes with it for the price of a used ES-8. That’s hard to beat. Just saw a used ES-9.
