From what I remember there is a plan to make Hydrogen available as an LV2 plug-in, so it could be used as something like NI Battery. Which means, in fact, that having a drum editor in Qtractor would be a good solution indeed. I've done quite a bit of syncing Rosegarden and Hydrogen in the past and the best way to do it was not to do it at all — I ended up using H2 as sampler, not as a drum sequencer, using Rosegarden's drum editor. This is because sequencing part of H2 is quite immature.
Rui,
