I have the 10-year-old Bösendorfer Imperial, and the new Steinway and Bösendorfer Imperial. On all of them I find the bass rather dead. At the moment I'm just redoing midi clips I previously have made of the last works of Bach, Beethoven and Schubert and posted on YouTube. I overcome this problem by selecting notes in the bass in the clips and raise their velocity by 5 to 20 V. (With the old Imperial I could set up two midi tracks with one to the bass and one to the treble; but I don't have enough computer resource for the new pianos. I'm currently using just the condenser, mid 2 and the tube microphones — and perhaps a high-sur.)
A much better way to do this would be with your new velocity editor, to make it so you could apply it to certain selected notes, just as one can with the EQ. For example, everything below C4 I would raise the left side of the velocity curve, and below C3 even more so.
It also makes me wonder if when the solenoids that apply the force to the hammers were developed, it was taken into consideration the fact that the hammers (and dampers) get progressively heavier from treble to bass, and thus more force needs to be applied. This would explain why the bass sounds dead. Even at a velocity of 127 the deepest bass notes don't sound very bright (sensitivity at zero or above). Nothing like they do on my 5'8" Baldwin grand.
I just discovered this update now. Are emails sent out for every update? Seems I didn't see one. Best, Phil
update: doing some more tests with this — recording the lowest three octaves at a velocity of 127 I discovered the Steinway has much more harmonics than the Bösendorfer. So possibly it's just the piano. But it certainly would be helpful to be able to raise the velocity of just the lower half or one third of the piano .
I also discovered that observing the velocity curve, that it didn't register the midi sensitivity. If the velocity was 127, it showed that whether the sensitivity was -100 or +100. Seems that should be rectified for it to be useful at all.
