Jack is very nice! You should use 'realtime lsm' kernel module to get realtime priority, and enable' preemptive kernel' in the kernel config. I also use zynaddsubfx soft synth and specimen sampler, together with my korg ms-2000R hardware. I use ardour for multitrack recording.

MC-50 is a very standard sequencer, and it syncs perfectly with seq24 midi, but not the other way round, and that is what I want, because the MC-50 has a nice turn/search wheel, which sends midi messages of his track position. Seq24 still can only synchronize with jack-sequencer and not with midi sequencer, so what I actually want to do is: 1. syncing jack-sequencer with midi-sequencer (doesn't work), 2. seq24 with jack-sequencer (works allready). I was wondering if PD could to the first task (stand between midi sequencer and jack sequencer), or any other tool. Is pure data ok? What can/do you do with it? I allready tried it a year ago, but seemed too complicated for me :) Greatings Hendrik >=20 > greetings, flo >=20 >=20 > "hwo...@pa..." <hwo...@pa...> schrieb am 07.11.05 18:16:5= 8: >=20 > On Wed, 2005-11-02 at 17:05 +0100, florian grassl wrote: > > hello there, > >=20 > > new to seq24 i of course have to draw my head for the creator of seq2= 4. it does exactly what i need - no bloated package running unstable and = such - cries out for being used live (and hell yeah, that's what i gonna = use it for). excellent! > >=20 > > I was wondering whether there was a way of starting and stopping seq2= 4 from a external source. usually, if the port of the device is known, th= ere is acertain message one can send to the device for a certain funcitio= n. > >=20 >=20 > I have tried the same to start seq24 with my Roland MC-50 sequencer, bu= t > I had no luck.
