Hi Ralph and fellow Jamstix users, Very Happy

I've got a strange problem, which never occured before.
I'm working on a song in Cubase SX3.1 and use Jamstix combined with DFHS for the drums.

The song is in 130 bpm (fixed tempo, no time track) and when I play it everything sounds fine and in sync, but when I export the MIDI and then reload the MIDI part in my song, the tempo of the drums has changed slightly... the beginning is in sync, but near the end they are almost half a beat late!? The tempo of the drum part must be about 129.95 BPM. Shocked

I've tried everything, rebooting, restarting Cubase, reloading Jamstix (it's version 1.81), but nothing helps.
I haven't got a clue, I always work like this, but this has never happened before...

Does anyone have a suggestion?

Thanks in advance,

Wim

Wim,
is it possible that you have a plugin in that project that uses PDC ?
Compressors, gates and the like (everything that uses lookahead) are suspects, as well as all DSP card based plugs and teleported stuff.
Don't know if that's the reason for your problem, but it wouldn't do much harm to try inserting audiom8.dll into an empty audio track and activating DSP offset in the mapping page. Worth a try ...
And then you might want to take a look at JS2 when it is released on Monday, timing accuracy with PDC was very important to Ralph during the Beta phase and it's rock solid here in Cubase 4 and 3.1.1.
(don't get me wrong, this is not meant as the usual "we don't know what causes your problem but simply buy the new version" crap Rolling Eyes , just as background info that might be of interest)
Hope you can solve the issue,
Rhino

Hi Rhino,

Thanks for your suggestions, they didn't work however.
I took the radical approach and deleted everything and started again from scratch. Now everything is fine and works like I expected...

Cheers,
Wim
