Hi Bruno,
my setup is quite similar to yours, it seems.
Ok, here's my detailed setup:
Main PC: HP Elitebook 8570p, Windows 10 Pro.
Secondary PC: IBM Thinkpad T43. Windows 7 and XP.
MIDI interface: Emagic AMT8.
Audio + MIDI interface: RME Fireface 800.
Thing is, when XL7 is slaved to Nuendo via MIDI clock, still exhibits a +/- 1-2 BPM drift. Just tested.
On Windows 10 and 7, AMT8 and FF800, in all combinations. I'm baffled.
Nuendo shows a steady 127 BPM, and on the XL7 the display fluctuates wildly.
May I ask, how did you check the MIDI clock sent by your CS on the receiving side?
Regards,
Zsolt

Hi Zsolt,2017-10-29 1:28 GMT+02:00 Adsr Multimedia adsr.multimedia@... [xl7] <xl7@yahoogroups.com>:I use a VJ app, which is MIDI controllable. It is capable of MIDI sync, BUT can't act as master (cannot send MIDI Clock).This app, when slaved to the CS, displays horrible MIDI jitter. The really sore point is the music.I have a pile of MIIDI-clocked synth gear, and everything (including a second CS, the MP-7) is happily clocked with XL-7, distributing it's signal across four stacked Unitor MIDI interfaces. Apart from Yamaha EX5, which (with the OS I have) cannot reliably sync to the external MIDI Clock, any other synth is happy to follow the BPM dictated by CS. I would suggest to check your VJ app with another source of MIDI Clock. I recall having a jam session with someone using Ableton Live (it was version 6, IIRC), and we couldn't get it follow the BPM coming from CS. All was fine and dandy, when we were just checking if the app receives the clock, but it couldn't play in sync.If you don't believe the ~20 years old gear, simply use another computer with a MIDI sequencer running on it.Just to make it clear: I'm not going to defend CS until my honorable death on the battlefield. There are (known) bugs in its OS, but I would simply suggest examining all the elements of your setup. Also, what MIDI interface do you use? Are you sure it doesn't introduce any delay in clock messages?Bruno
