[Ardour-Users] Hydrogen/Ardour sync problem

[Mark Greenwood]

I think Arnold has the key to it actually - it might well be the 
Humanize controls in Hydrogen that are the problem. I've done quite a 
few experiments now, it's still not entirely clear to me what's going on 
but if I create completely new projects in Hydrogen and Ardour and don't 
use Humanize, the phasing effect seems to go away. I'm not 100% 
convinced yet though and I'd be interested Paul if you know of 
version(s) of Jack which exhibit the problem you describe.

Thanks all,

Mark.
