This is not done yet. also bad english and not fully tested.
This tutorial is about: external softsynths (hydrogen, zynaddsubfx)
It's very easy to setup this in MusE.
- start jackd with or without (qjackctl)
- start MusE
- start hydrogen and (or) zynaddsubfx BUT be sure you select jack audio output on both programs. (with zynaddsubfx you do this on startup with a command line tool) (in hydrogen you can change it in the preferences menu)
- next step is to trigger midi from MusE to one of the apps, that's easy.
- in MusE go into the "settings" menu and then "midi ports/soft synth"
- in the "soft synth configuration" dialog click on the drop down menu in the "Device Name" tab and you'll get a list of possible IN/OUT midi devices available on your system. select "hydrogen" or "zynaddsubfx" here.
- now that the device(s) are visable to MusE as midi outs you can close the "soft synth configuration" with the keyboard key "esc".
- no add a "midi track" in the canvas with "CTRL+J" and clicking on the "O-Port" should list a zynaddsubfx output. be sure you also set midi channel right. for hydrogen it's 10 in zynaddsubfx it's 1 in MusE for 0 in zynaddsubfx and "2" is for midi channel 1 in zynaddsubfx and so on.
- finnaly you can press the "rec" led in on the same line and all midi input is also routed to zynaddsubfx or hydrogen, whatever you chose.
- if your midi keyboard is set appropriate and MusE gets the midi input it'll forward it to the selected outputs (no need to go in record mode because you should be able to trigger the device already).
now we want to record it's output (audio) that's also easy
- first add a "input" and a "wave track"
- the input must have 2 channels (stereo) and you have to select which zynaddsubfx output is directed to which channel. (this is done by clicking on the "input 1" and then on the left below the vertical slider for input amplification there is the iR switch) select both channels.
- now you have to amplify the signal because by default it's -60dB and you won't hear even noise! trigger some midi signals and select the slider in a position which indicates that some audio output of zynaddsubfx or hydrogen is getting in the "input 1".
- after this it would be nice to hear the input. add a "output track" and calibrate the output amplification and the output channel (as above with the iR but this time you select the input1 as iR for both channels left and right)
- we have to set the oR (output channel, too) it's near by the iR switch. Set it to the alsa output of your soundcard and be sure you can hear anything comming from your computer. for example try "aplay anything.wav" and if you hear something then the mixer values are correct if not you might have to calibrate the mixer values with "alsamixer" in the console or "qamix" in the Qt gui.
- now call the mixer dialog with F10 and trigger some midi data again, try now to find out if the audio routing is done correctly and maybe you have to go to the "routing" dialog which is in the main menu of the mixer settings (yes the mixer dialog F10). There you select the aproppriate audio output for MusE out1 (if not done already in the "output1" oR setting.
