JACK and Qjackcontrol
It is highly recommended to run Aeolus on top of the JACK soundserver. The following steps require that JACK is configured and running. Though that JACK is a command line application, it is recommended to use qjackctl as a frontend to control your audio system:
For the first two steps click on the button »Connect« in qjackctl. Choose the MIDI tab and connect your soundcard's MIDI input (or any other MIDI source generating program like Kmid or Muse) to the Aeolus input:
Additionally you can use a tool like aseqview to check if there is incoming MIDI data at all (don't forget to connect it to the same input as Aeolus like shown in the screenshot above & NOTE the channel numbering differs by 1):
Playing on your keyboard (or other source) now should show the incoming MIDI events as activity in aseqview.
Use the page »Audio« to connect the audio outputs of Aeolus to the outputs of your soundcard:
If you do not get any audio output, you can use an application like Meterbridge to check if Aeolus outputs audio:
As meterbridge needs some command line arguments to be started, here is an example:
In the Aeolus main window, click on the MIDI button. This dialog allows you to tell Aeolus which partition will respond to a certain MIDI channel:
In the section called "Keyboards", select which MIDI channel will play which division. A common setup maps MIDI channels as follows:
In the section called "Divisions", select which MIDI channels are used to control swell (MIDI CC 7), tremulant speed (MIDI CC 12) and depth (MIDI CC 13). The current instrument doesn't provide swell and tremulant for division I, but for divisions II and III. In most setups the same MIDI channel as for the notes will be used. The control channel (in the current instrument) is for controlling global parameters.
To save these settings, press the button »Save« in the main window.
Switching the stops
Finally, switch on and off stops as you like and enjoy playing Aeolus!
There are 32 presets in 32 banks. Use the arrow buttons to select a preset. Press the button »Store« to save the current registration. Press the button »Recall« to load a configuration form the currently selected preset.
