Brad, I don’t know about others, but the reason I keep trying to point out these things is because I think the Parva is a great synth. If I thought it was crap, I would have sold it off long ago and been done with it.
However, I think you have something special with these oscillators. Even playing simple chords with a one oscillator triangle wave and filter wide open sounds very nice. It’s big and full and pleasant to listen to.
For me, the high pitched whine is the only kink in the synth. It’s not noticeable with 1 or 2 keys down, but if you set the OSC 1 volume to 30 or so and triangle wave and play some basic C maj chords below middle C you can hear how that noise is present in the sound.
Even if it required a hardware mod to the voice cards to reduce that cumulative noise, I’d be more than willing to send my cards in and pay for the modification (unless it was something we could do in the field).
In any case, don’t be discouraged by these comments - these are reports from people that believe in this synth and like everything it does to this point. Cleaning up some of these unfortunate sonic artifacts are (to me anyway) way more important than new features to this already full-featured synth.
