It would be easier to troubleshoot if you could tell us what sounds like its out of sync? You hear a delay from the time you press start on the clock source to when The NDLR starts playing? Or does someone get a beat off tempo?
The NDLR doesn't "regenerate" the clock, it uses the external clock ticks as they arrive to drive the parts, just as if the NDLR were generating them internally. So if the external clock isn't perfect, The NDLR won't be either, but it will be in time with the clock source (for better or worse). The trade-off to this architecture is, the NDLR practically "hangs" when there is no incoming ticks. MIDI is always the priority and the heartbeat of The NDLR so it won't move forward without them.
When using external clock, the clock display on NDLR is a real time BPM meter. It accurately reflects what it is receiving. The BPM calculation happens very frequently and there is no "smoothing". Its what you see is what you get. We've compared the BPM display to several other measuring tools and its actually more accurate and faster than most other hardware devices. For instance, if you apply external clock to a Beatstep Pro, there's a delay before it shows the clock, and probably some smoothing going on so its not jumping around a lot. We thought about doing this too, but we liked having the real time measurement and the decimal place.
On the other hand, if there's a tick with a severe jitter and The NDLR BPM meter happens to sample it, it will show it. However, you will never hear that as its a fraction of the 24 MIDI clock ticks that make 1 BPM.
Do you hear something that makes it sound like its out of sync?
