Hello All,
Jack Audio Connection Kit 0.2.22
Rosegarden 1.5.1
Ardour 2.1
Fedora Core 6 with Planet CCRMA sources.
Using Jack Transport as the control for Rosegarden and Ardour. (This is
my first project doing using Ardour.)
In Rosegarden, I have a BPM of 160. I'm using Rosegarden to send MIDI to
my external Roland Sound Expansion modules. The audio output of the
Roland synths is sent back to the PCM Audigy2-ZS sound card in the
computer. I'm recording into Ardour.
I start recording. Ardour is getting a BPM of 120, not the 160 BPM as
Rosegarden is set to.
The Qjackctl window of Jack shows a BPM of 120.
How do I change Jack to use a BPM of 160? Is this a command line
setting I should be using?
Thanks All,
Stephen.

With jack-transport you have to choose on of the clients to act as
time/tempo master. Per default (at least in my setup) Ardour is setup
to run as that.
So either you change tempo in Ardour by rightclick on the Tempo line,
choose Edit and set it to 160 or you disable Ardour as time master
(button below the sync setting, right of the secondary "beat" clock)
and make sure Rosegarden is set as master.

Only the first of these will work in practice, as Rosegarden does not
support JACK tempo master (nor, indeed, slave).

Thanks Peder, Chris,
This is my first time to use Ardour, and I mistakenly thought that the
Time Master button (lit green) was referring to which source to use as
transport control in the button above Time Master. The values of that
button are Internal, MTC, and Jack.
Chris, on Rosegarden's Configure Rosegarden-Sequencer-MIDI Time Code
Mode, should I set this to MTC Slave? Would that allow the BPM to be
controlled by Ardour?
Or should I be setting the MIDI Clock and System Messages to Accept
Start, Stop, and Contnue to have BPM control by Ardour?
I like using Jack Transport to control Rosegarden and Ardour, so on
Rosegarden I have Jack Transport Mode set to Sync.
Thank you,
Stephen.

Jack control and MTC are two different things with no (direct anyways)
connections to each other.
To enable Jack transport in Rosegarden you go to Settings->Configure
Rosegarden on the General page, under Behaviour (as per
http://rosegarden.sourceforge.net/tutorial/supplemental/hydrogen , see
also http://www.rosegardenmusic.com/doc/en/transport-external.html)
From Chris' answer, I'm not sure wheather Rosegarden honours Ardours
tempo or not; you might have to set them both to the same tempo
manually and just use jack transport to start and stop everything. But
you can always try setting different tempos in Ardour (with it as time
master) and see if Rosegarden plays along.

That's correct, unfortunately. There is no way to make Rosegarden
track tempo changes from any external source at all at the moment, and
no way to make it send its own tempo changes to any external
destination.
