How to route to soundcard? - papoy - 12-02-2012

How can I route output to the soundcard within MUSE?

Hi papoy,
There is a track type called Output, one should be created on startup, take a look in the mixer.
There's a button on the output strip with an audio jack icon, if it's unconnected it is colored red. If you hover the mouse over, it says "output routing"
Clicking on it you should show a list where the audio connectors are listed, select the correct ones for both left and right.

Hope that helps!

Under the output audio jack icon every channel is checked (that's channel 1&2, playback 1&2 for both channels). I don't know what these all mean.

Assuming you have started jackd before starting muse (you will get a warning if jack is not running), the channel 1&2 should probably named channel L&R. The listed items are the outputs that jack displays, this should correspond to the outputs on your audio card.
To preserve stereo you should only connect one output to L resp R.
As it seems there are already connections here the problem seems to lie elsewhere.
If you haven't viewed the video tutorials please have a look. They are for an older version but mostly relevant.

If this doesn't help you we can try some further analysis, just get back here.

It seems that channel 1 as well as channel 2 both invoke the softsynth (the sound is the same). For both channels there are checkboxes for L and R. How can I distinguish between softsynth and soundcard?

Could you describe what tracks you have created and what you want to be played through the output?
I must admit I'm a bit confused as to what you want to happen.

In general, MusE handles two types of data, midi and audio. Midi tracks do not produce any audio unless they play to an internal softsynth.
Channel 1 and Channel 2 should be the stereo output of your soundcard.
Maybe it's time for another instructional video <!-- sSmile --><img src="{SMILIES_PATH}/icon_e_smile.gif" alt="Smile" title="Smile" /><!-- sSmile --> I've been meaning to do that..

No, each channel (they are called that) has two checkboxes, which control the output to the left and right channel (they are called system:playback1 and system:playback2). This could mean that channel 1 and channel 2 are different soundcards, or the same soundcard.

I understand that one can use a softsynth to proceduce actual sound (and this works fine). Another thing I mean to try, is, the use of the soundblaster's internal synthesizer.

I have a midi track with the DX7 DSSI synth (hexter) set to channel 1. The output track is set to channel 2. I don't really know what this means. Even when I change the channel number, nothing changes. The configuration works fine though. The aim of this topic is how to use the internal soundblaster interface though.

Ah, ok, now I see what you mean.
First to try explain the channel 1,2 confusion.

When you have a playing softsynth in muse you will have a chain of "tracks" connected in MusE that lead to the soundcard.
Something like:
Code:
midi track -> soft synth -> output track (channel 1/2) -> system:playback_1/2
The output track is by default set as a stereo track and thus has two outputs, hence channel 1 and 2, in general these should be connected channel 1 to system:playback_1 and channel 2 to system:playback_2. It is possible to connect them any way you'd like but to preserve left/right stereo separation they should be set like this. Which also should be the default.

----
About your soundblaster card, it is possible to use this as a synth from within muse, I used to do it, but this was many years ago and I've forgotten most of what is needed to get it working.
One important point is that MusE does not contain any specific support for these cards. We talked about adding it long ago but in truth this configuration is not commonly used anymore so it has never been done.
I googled a bit now (the term 'awe synth linux' does give a bunch of results) and as far as I can remember you loaded soundfonts using a utility called sfxload, the synth itself should already be listed as a midi device in MusE if Alsa is properly installed.

I'd suggest an alternative path though.
The soundblaster synth is a soundfont player, there is a soundfont player available as software called fluidsynth, as it happens a muse-variant of this synth is already available within MusE. It's quite easy to setup and works very good.
Using the synth on your soundcard has it's benefits if your system is too slow to run softsynth properly, in most other cases the softsynths are easier to handle and work just as well.
One last thing to remember when using softsynths is that if you are going to play the synth live from a keyboard (which most people want to, when recording) you need to set the jack-buffers small or there will be a noticable delay between hitting a key and hearing the sound. I usually run with jack buffers at 128 when recording.

... lots of information to digest, hope it isn't too overwhelming!
