Hi Ricardo, So simply running a line level source thru MSP then straight out gave you 50 ms? Interesting, thank you for the information, I've no way to test that myself -daniel
I got these results now, 11.dec.2000: G3/350 Blue- Motu2408 mkII Driver: ASIO PCI-324
In-out latency test: 2226 samples = 50.476189 ms
Delay lines: 74 samples = 1.678005 ms
I have also found the fact that midi behaviour is quite unstable when using OMS, the Miditimepiece(USB) MTP AV under Macos 8.6 and running MaxMSP.
