Hi

I just got a new soundcard (Emu 1820m) and it has a nice direct monitoring with effects section so I tried upping the latency to higher values than I'd used before.

The thing is that in a track I've done, the higher the latency, the more out of sync Jamtix gets with the other tracks.

Jamstix is triggering BFD (not internal).

It starts behind the rest of the tracks and stays behind, the amount depending on the latency.

This is in Cubase SX3.1. Any ideas?

This should not be a Jamstix issue as you are routing the MIDI output to BFD so Jamstix' involvement ends when the MIDI data is sent to Cubase.

I just double-checked this here and even at high latency the MIDI output recorded by Cubase from Jamstix is on time. Please check that on your end.

Hi Ralph

You're right, even at 100ms latency, the Midi track records the Jamstix output in time. Only when playing back "live" the delay is there.

I am assuming that there will be a delay of 5ms on a 5ms buffer too.

Cheers for the fast reply, so it's narrowed down to SX3 or the Emu....

Cool

Hi

I loaded Battery 2 and LM-7 into the project and the two of them are playing back in time, just not BFD.

I'm going to post on the FXpansion forum.

Cool

Update....

FXPansion confirm that there is no latency added by BFD.

I haven't had any replies on Cubase.net but I have tried loading BFD and Battery 2 into a new project and have Jamstix play them at high latency.

BFD doesn't show the same bad latency problem as with the other projects, but the drum rythms have very bad timing (although keep up with the tempo). Again, the recorded midi output is fine and Battery 2 plays fine.

I fired up the Cubase LE I got with my soundcard and worryingly/interestingly there are no issues with Jamstix playing BFD at high latency.

So it looks like its something fishy with SX3 and/or my setup, although without any kind souls trying to reproduce I can't be sure.

The reason for this problem has been discovered by another SX user....

Original thread

Basically, put Jamstix before BFD/whatever drum module in the VST Instruments rack and everything is hunky dory.
