hi, try the hydrogen-midi-clock branch.
http://svn.assembla.com/svn/hydrogen/branches/midi-clock

with this branch you can send and receive midi clock ,spp and midi-start & stop.
this make it possible to control external hardware like a korg kaossilator pro or a
mopho.
also hydrogen comes with a build in tap-tempo. its possible to map midi note or midi cc
massages to the different tap tempo functions.
hydrogen has two differnt tap tempo implementation.
1. normal taptempo with 1/4 tapping (AltGr + \)
2. advanced beat counter. 1/1, 1/2, 1/4, 1/8 tapping is adjustable( , key). also it's
adjustable, how many taps will calculate the tempo. minimum is two maximum is 16.

now you can tap the tempo in hydrogen and other jack transport or midi clock applications
and devices can follow your tapping.

i personal prefer midi clock to sync different sequencers.
1. because its the easy to use and most hardware devices comes with midi clock
implementation.
2. midi clock will also send if the trasnsport is stopped.
3. midi clock is independent from frame positions or song positions. it only send a
simple quarter note based clock rate. this keep you against many side effects you will run
if you try to use jack transport.

greetings wolke
