its definitely a bit of a challenge at first, but give it a little more time and experiment with it. try turning the filter resonance all the way up and filter close to all the way down, and turn up the amp and filter LFO, then fuck with the lfo speed. the arp is also fun too.
also keep in mind that when you have the oscillator faders more than half way up, that it overdrives the filter and gives a harsh sound. if you keep them under half way, you can get a smoother, more vintage sound
