I don't want to mix them for performance use. (Indeed, it's bye-bye to the Clav sounds. Ivory is so much better.)

I was just mixing them as a tool to assess the latency.

Mess with the buffers, Sample rate, etc on ivory's setup. You should be able to achieve 5.2 ms latency. Use presonus usb drivers instead of asio4all

Alpha: Ivory 1.5 has a buffer setting, but it's a memory buffer (small/med/large), intended for slower computers:
- Buffer size controls the Ivory performance by adjusting the amount of RAM used to generate notes.
- Slower computers will need to use a larger RAM buffer, while faster computers can use a smaller buffer.
- This setting does not affect latency.

Yes, I've been using the PreSonus ASIO driver. It offers these choices:
SYSTEM PERFORMANCE .. INPUT LATENCY ............. OUTPUT LATENCY
Highspeed ........... 93 samples .. 2 ms ...... 280 samples .. 6 ms
Rapid .............. 172 samples .. 3 ms ...... 365 samples .. 8 ms
Fast ............... 172 samples .. 3 ms ...... 815 samples . 18 ms
Normal ............. 300 samples .. 6 ms ..... 1337 samples . 30 ms
Relaxed Normal ..... 556 samples . 12 ms ..... 2181 samples . 49 ms
Relaxed ........... 1068 samples . 24 ms ..... 3069 samples . 69 ms

The default was "Normal" ... 6 ms latency, 300 samples.

Previously (with ASIO4All) I used 320 samples, and it worked well. When I tried 256 samples it would sometimes crackle.

But with the PreSonus I tried "Fast" ... 3 ms latency, 172 samples.

It works. I can hear NO latency at all.

Result!

Enjoy it! Play around with the resonance and room size and wet/dry settings. I love to play ragtime and upbeat pop on the C7 setting, I love to play classical and pop ballads on the Steinway (and Fazioli) setting. I don't much love their sampled Bosendorfer for much, unless I needed another drumkit

The Bosie tone is mellower, suitable for some things. I like the German D (Steinway?) better for most purposes. (I don't have the Fazioli ... this is v1.5.)

The room size is quite useful. I like "room" for Baroque, and "concert hall" or "recital hall" for most everything else.

I've always thought the dynamics on the Clav were too limited. Ivory does away with that limitation.

It also allowed me to correct the velocity curve. The Clav won't send the full 1..127 range for velocity. It only goes from the teens up to about 105. The correction in Ivory makes it much more playable.

It's already been said, but it bears repeating: Why can't Yamaha put a sound this good into the piano ... even if it were only one of the piano sounds?

Mac: If you decide to try Ivory 2, get Italian Grand, which is just the Fazioli. It is a cheaper investment and is very versitile. Ivory 1.5 is great, though, enjoy that for now!

They totally can, they just won't - even though it's long past due, particularly for their no-compromise high-end products like the AG.

Agreed - I bought a fairly high end Roland some six or seven years ago - poor investment as the sound became tiring and thin with time.

Fortunately it sends the full range of damper and volume control messages, and has a reasonable imitation of let-off at key stroke bottom.

I'm surprised that your CLP 240 doesn't send the full range of values as it's a full featured DP.

The Clav has half-damper. But Ivory 1.5 doesn't support half-damper. (The new Ivory v2 does.)
