OK. Great! Thanks for the info. I'll wait a while.
I also run MusE on an AMD 64, an Athlon. It is single-core, a bit old now.
With a Delta1010 ice1712 card.
I blacklisted my on-board audio because even when I disable it in BIOS, the
OS still somehow finds it and pollutes the daily ordering of device listings.
There is a MusE command-line debug switch -D which gives us information.
Sometimes it can be a plugin or soft synth misbehaving with us.
There are switches to turn off loading of the plugins and soft synths.
Hopefully these will help narrow it down.
I fixed a freeze or two recently, kind of obscure though.
Current release is 2.1.1, next is due out soon, plenty of great new fixes
and features, and new online docs. Would be cool if you could run a
recent version but it might require building source but it's not too hard.
We have removed the Doxygen requirement for example :)
As a midi editor she's fairly advanced, per-drum or note midi controllers
like poly-aftertouch for example.
But, gulp, we're about to face some seeerious competition on two fronts.
Oh, apologies for breaking in on this Bitwig thread, carry on.
And congratulations to the Ardour team expecting the new baby!

I'm looking for a simple tool where I can point it at an http audio stream, define a number of seconds to detect silence and exit with a non-zero status if silence is detected. It seems like this should be easy but I've been search high and low for such a utility and nothing simple exists. Unfortunately I'm not much of a developer, but this doesn't seem like it would be that difficult. Maybe it's harder than I think, hence no tool that I can find.
Thanks

I have obviously been a bit out of the loop not noticing this before,
but anyway, the Steem Source was released under GPL on July 01, 2011.
It's got MIDI in it which is why this is interesting for us. There are
lots of editors for antique synths out there (or for their emulations)
as well as a bunch of funny auto-composers (M, Ludvig) and other
MIDI-toys. The original Steinberg Cubase Light is still freeware if you
need a 16-track sequencer.

Hi all,
This weekend, starting a midnight (EST), Saturday morning (Mar 9), the
Systems Support Group at Virginia Tech has scheduled storage maintenance.
The storage that supports linuxaudio.org will be unavailable from
midnight until noon Saturday (EST) and hence the server will be offline.
thanks for your understanding.

Hi all
I have just installed the lv2 GxAmps,
but when I run the plugins on jalv, some messages appears on the terminal:
"cabconv.update fail.
cabinet convolver disabled
ampconv.update fail.
presence convolver disabled"
Does anyone know how to solve this problem?
Regards,
Andre
Hi all
i'm trying to sync arpage (jack synced arpeggiator) to Hydrogen:
in hydrogen i enabled jack transport + set hydrogen as master
Arpage gets triggered when i hit play in hydrogen, but it does not do what
i expect it to do (the tempo is all 'weird')
if i do the same with qtractor, ardour or the jack_transport utility as
jack master everything works as expected
now i'm trying to find an easy way to see if there is any difference
between the way hydrogen and the other apps start/stop/'master' the jack
transport, but so far i cant see any difference
is there any app/utility that can give me detailed info about jack
transport ?
i have logged a ticket (including a screen recording @ bottom of the
ticket) of this strange behavior :
https://github.com/hydrogen-music/hydrogen/issues/81
any tips ?
grtz

Hey all,
I'm currently attempting to stress test my setup of -rt kernel, rtirq
scripts, and a Jack client program I've been working on.
So my idea is to create a script that runs the programs, and also a
cpu-load generating program (cpuburn or alternative).
Then collecting stats based on Xruns, % DSP load, etc.
I intend to show (trough brute force) that an application is RT capable on
machine X with a latency of Y ms.
Of course this won't be 100% representative, but the stats will show some
RT-safe-ness.
Has anybody done this kind of profiling / stress testing with JACK before?
Hints / tips / advice / etc welcomed! -Harry
