Ivory!...

...5th place was a surprise...



As is evident, the precise starting point is always a little vague but the picture should be clear, Ivory getting into its stride at around 10ms, pianoteq at around 14-15ms. Note, this is MIDI trigger to VST processing time only but the additional components (key depression, issuing of keyboard MIDI to PC - monitor-to-ear etc) being common to all VSTis, the variation in totals should exactly reflect the varation here.

My thanks to lolatu whose sterling work in quantifying typical AP latency aroused my curiosity about the relative performance of our currently most popular libraries. Though Pianoteq falls to last place in this test it should be clear from lolatu's overall estimate of 45ms for his AP - a result which ties almost to the millisec on the identical test I carried out on the AP here - that the extra two or three millisecs are relatively trivial.....contrary to what we might have been led to believe up until quite recently.

You'll have to give some detail about your latency measuring method for the results of your test to mean anything.

Pianoteq taking time to calculate sound creation shouldn't be surprising.
