Oddities in Diva's sound at note start

[Synthbuilder]

Win XP SP3; Diva 1.0.1; Host Live 8.3.

I've noticed that the oscillator pitch lags behind the note on. In other words the envelopes are firing before the oscillators change pitch for the new note. This occurs on every new note if the pitch has changed in monophonic mode - alternate octave notes for example. Whilst in polyphonic mode it's noticeable on every note played on a voice that had previously played a different pitch.

The time interval between the start of the attack phase and the VCO updating to the correct pitch does seem to be very small, 3mS or so, but it does add a slight click to every new note played if the pitch has changed. In monophonic mode it's often not heard, but in polyphonic mode where you may be playing with both hands and thus a bigger pitch range, you do get a noticeable 'thwip' at the start of many notes.

Interestingly, you do get a similar effect on some DCO polysynths but it's unusual to hear it on a VSTi.

This is one of the artifacts we've mostly removed in version 1.1.
