Midi Latency

I am using SONAR 2 with TASCAM 428 USB Midi Interface - so midi is being routed Mother Keyboard -> tascam midi-in -> SONAR -> tascam midi-out -> sound module.
Initially, this works well, but over time (eg 2 mins) a time lag is introduced making playing impractical.
Playback from SONAR to Sound module is instant, so my guess is it has something to do with the midi echo in SONAR.
The problem is solved by opening 'midi interfaces' and closing (thus reinitializing).
Please help.

You need to edit TTSSEQ.INI and add a line somewhere which reads:
IgnoreMIDIInTimeStamps=1
I can't remember the exact location, but it's documented in the SONAR README file.

Thank you so much - I have tried TASCAM, TURNKEY and even CAKEWALK themselves to try and solve this problem. NOw, after months, I have the answer - and will no longer have to record my midi in sections....
Thanks again, Steve
