Here’s some initial feedback.
First - it is a lot better. Update was no problem, all voice cards at 0.64 (main board at 0.61).
My goal was to take an init patch (all VCOs off, VCA envelope at 0,0,127,0, VCF fully open, clean OSC ON, slop 0, detune 0) and start from there.
I will concede there may be user error, but creating that patch and then attempting to save it was a mess. I still don’t know why I can’t save and recall something reliably. It comes back either not saved at all, or partially changed. Again - I concede it could be user error, especially since I wasn’t looking at the manual and there’s no confirmation when you save or load. It also could be I have a different patch auto-loading on boot (forgot to check that).
Anyway, back to the testing. If all DCOs are at 0 and the Volume pot is turned up and you press a bunch of keys, you hear a high pitched whine very clearly. Less noticeable with only 1 or 2 pressed, but adding keys really makes it obvious.
With any oscillator or noise turned up, you can’t really pick it out.
I will state, but not swear to it, that initially I thought all voice volumes were consistent, but after running through the DCO and VCF calibration I do hear some variation between voices, but it is way way better than before but still noticeable.
Again - not sure of the interaction between the newer voice board OS and the older main board, so doing any of the above could have overwritten/negatively impacted the voices.
My summary though it that the volume between voices is more consistent, the overall levels on the Parva are easier to control to get a good output gain, and the tuning is still stable. The filter resonance still comes on strong between 105 and 120, but either I’ve been away from it for a long time or it’s been changed a bit, but the filter in general sounds nicer inmost of the modes than before (yes, very subjective comment). Don’t know what else I was supposed to test since I didn’t see a list.
