MusE and Jack-MIDI

as on this page seem to respond the professionals, I answer my question here too. <!-- sWink --><img src="{SMILIES_PATH}/icon_e_wink.gif" alt="Wink" title="Wink" /><!-- sWink -->

It´s that I got problems with my ALSA-MIDI connections. If I use them, they make a cracking noise. So I would like to connect MusE just in Jack-MIDI. But I´m not able to do that, neither with a2jmidid. a2j creates in Jack (Jack-MIDI) a port called "MusE sequenzer [130] (playback): MusE Port 0". But in MusE in the settings in Midi-ports doesn´t appear that.

So I´m not able to send MIDI to MusE via Jack-MIDI, nor am I able to get MIDI from MusE and send it to an instrument via Jack-MIDI. In ALSA-MIDI I may do that, but as I say, I got some troubles with ALSA-MIDI (not just using MusE, also with other programs), wich I don´t have with Jack-MIDI.

On the main page of MusE ( is written, that MusE supports Jack-MIDI. That means, that it should work even without a2jmidid, rigt? How could I do that?

Thanks and greets, Nils.
Hi Nils,

I can't check exactly how this is done until I get home. Until then I just wanted to make sure you are using MusE 1.1 ?

Oh no, now I see, that it's just 1.0.1 - Sorry for that. Seems as if in the default repository of Ubuntu Studio (Maverick Meerkat) only 1.0.1 is available.

I will update and report. But at the moment I'm not at home neither.

Again sorry and thanks for the reply.

By the way: I think the 2.0 version is still not recommendable for a newbie, right?
Hi Nils,

no problem at all <!-- sSmile --><img src="{SMILIES_PATH}/icon_e_smile.gif" alt="Smile" title="Smile" /><!-- sSmile -->
It's a bit of a problem that old versions still exist in various repositories. If you are in contact with the ubuntu-studio folks I would not mind if you asked them to update the muse version.

As for 2.0 my feeling is that it is already quite good, many new features and pretty much as stable as 1.1. If you know how to compile you are quite welcome to try it.
We will release a beta soon, this weekend hopefully.

Hi again,

read your original question again and thought I would ask about the crackling noise.
What exactly happens, could you describe what you do when this happens?

I have not heard that there should be any such problems..

Hi Robert,

as I wrote it's not a problem of MusE. It also happens with rosegarden or with ZynAddSubFx, when I connect them in ALSA-MIDI.

The cracking noise appears when some MIDI-Information is going through (in my case note-on and note-off). When I press on my keyboard a lot of keys at the same time (means a lot of MIDI-Information), then it's worse. When I press the keys and hold em down (f.e. with some organ sound), then all the time the keys are pressed no noise appears. Just when MIDI is going through. Maybe it's the MIDI-Information that becomes for some reason audio.

Sorry, but I'm absolutely not in contact with the guys from Ubuntu-Studio, but I will write them anyway. I'm absolutely new to music with Linux (for one month now), before just worked on other platforms. I'm at the moment studying in Berlin and constructing a 7-channel 3rd-order system and decided to do it in Linux. But until now I never compiled. But if you release beta this weekend, then for sure I'll try it.

Thank you again and I'll write here when something new happens with my things.

And of course: Thank you very much for the program. MusE is an excellent sequenzer.

MusE 1.1 got what I needed. After a short test everything seems to work and the programm seems to run quite stable.

Cool thing. <!-- s8-) --><img src="{SMILIES_PATH}/icon_cool.gif" alt="8-)" title="Cool" /><!-- s8-) -->
Great <!-- sSmile --><img src="{SMILIES_PATH}/icon_e_smile.gif" alt="Smile" title="Smile" /><!-- sSmile -->

Happy sequencing!
