Re: [Rosegarden-user] Midi Mixer problem

2016-01-20 Thread Home
Hi Ted, Michael, Abrolag,

Thank you for all your responses on this.
 From Ted's guidance below, I was able to remove volume controllers in 
the matrix editor.
This has given me back the ability to create my own mix.
I'm blown away by what I can do with Rosegarden, now that I better 
understand its subtleties.

Thanks again,
Paul.

   Yeah.  It's never a reliable guide.  You never really know what'll 
run until you try it.

Just poking my nose in (again)

As I remember ARM cores manage significantly fewer clock cycles per
instruction, so CPU frequency is not such a reliable guide.

   It should be.  However, rg is still somewhat wasteful of CPU, so it 
might not work well.  A MIDI sequencer should run fine at 900MHz on a 
single core.  I run CakeWalk on an old 1GHz machine with no problems at 
all.  Lots of CPU left over.

I haven't tried, but I think it's probably pretty straightforward.  I've 
cross-compiled other Qt applications for two different ARM platforms. 
Building the core application should be quite simple; especially since 
you can build it from within a running environment.

I'm not completely sure about the many dependencies, but it seems likely 
that they're all achievable.

To test this, I fired Rosegarden up on my rather faster quad core and 
opened just a stupid number of editor windows.  I monitored my CPU 
activity, and it seemed to be distributed pretty well across the cores.

Ted Felix reduced Rosegarden's CPU usage very dramatically since the 
last time I tested on lower spec hardware.  I probably could have 
managed to make this go a few years ago, and today, the chances are 
considerably better.

I'd go for it.  It will probably work.

[Rosegarden-user] Rosegarden on Raspberry Pi

2016-01-20 Thread Todd Pierce
Hello All,

Forgive me if this has been asked before, but has Rosegarden been ported to
the Raspberry Pi ARM processor?

People have been worried that the Pi wouldn't be powerful enough, but don't
you think that a quad core 900 MHz processor  with 1Gb of RAM is good
enough?

Any advice is appreciated.

Sincerely,

-Todd

The Rosegarden group is:
https://soundcloud.com/groups/rosegarden

To post on it, you need to create an account with soundcloud, then when you
upload a track you have a choice of also joining a group.
