To add: I'm using Windows 10, and I was on Synchron Piano Player version v1.2.116 (updated this morning to 1.2.118 but haven't been able to test it out yet, but I did try reinstalling the Player yesterday, before .118 was released). Tried in both standalone version and hosted in Cantabile.
A few more details, which lead me to suspect that this might be a bug in some versions of the Synchron Piano Player:
1) The effect of the 4th pedal seems extreme. I wonder if somehow the effect has been fully or partially applied to some or all notes when the pedal is off, then gets doubled up when the 4th pedal is turned on/depressed.
2) In addition to the bass, the upper treble also seems a bit restricted in dynamic range.
3) Really, it's the mids/upper mids that seem to dominate. Possibly D4 in particular is louder than other notes?
4) On those bass notes in particular, it really does feel like I'm hitting some sort of limiter at around 3/4 of max velocity. Very little if any change in volume or tone at that point. (I checked and velocities are definitely registering correctly in the Synchron Piano Player.)
I'm just an amateur pianist, so I'm not able to dive into MIDI or apply EQ to any meaningful degree, and I don't want to start editing this piano note by note. But if anyone else on the VSL team can walk me through how to provide more info, I'll do my best to supply it.
This instrument has some great qualities, and I really want to love it, but right now I can't see myself using it for much of anything composed after 1800 or so.
Best,
Mike
