Well, it also features a vocal processor, sampler, and fx pedals. But the Parva was the only synth used on the album. You can listen here:
I absolutely love the slightly filthy, raw sound of the parva. In addition to being a good polysynth, when running multi-timbrally, it makes an excellent mono (bass, lead) as well! It’s great being able to route out each voice to different FX for tracking, etc. And this thing totally comes to life with a bit of pedal reverb/delay!
