Yes, strange, but not unheard of: http://forum.cockos.com/showthread.php?t=45801

With ASIO4ALL I get the MIDI events recorded between, -202 (that's early!) and 440 samples (at 44.1kHz sampling) of the time they are sent. Some numbers in-between just to show how it varies: -138, 62, 184, 314, 395. So, with ASIO4ALL the range is 642 samples, roughly 14.5 ms.

And just to make sure... this is MIDI loop back recording. Also, this is with ASIO4ALL latency compensation set to 0.

Using the Lambda ASIO driver, numbers are more consistent: 138, 161, 184 (that's it, of the 12 tests at 3 different buffer settings only these three latencies turn up). So, with Lambda ASIO the range is 46 samples, roughly 1 ms.
