=== Basic Principles
|
|
|
|
Fluajho loads exactly one `.sf2` soundfont. A soundfont can contain several instruments, of which
|
|
up to 16 can be used simultaneously.
|
|
|
|
Each of the instruments can be loaded into one MIDI channel. To do this, first select a bank in a
|
|
channel (Bank 0 if in doubt) and then a program.
|
|
|
|
On the first launch a small standard soundfont is loaded, which is General Midi (GM) compatible.
|
|
|
|
Fluajho itself has no option to play notes. To control the sounds, you send MIDI data to our input
|
|
port via JACK. The channel is a property of the midi signal and is already selected in the
|
|
sequencer.
|
|
|
|
Each channel has two separate audio outputs in JACK: Left and Right.
|
|
|
|
Saving and loading your project is done by the New Session Manager (Agordejo). There you will find
|
|
a "Save" button.

== Description of the graphical user interface and its functions
|
|
|
|
Use your browser's search function to locate the individual letters like [B] and their explanation.

|
|
|
The *[A] File* menu contains "sf2 Soundfont load" (keyboard shortcut: Ctrl+O).
|
|
Only one soundfont can be loaded at a time. If you want to use several different soundfonts at
|
|
once, just start Fluajho several times. Saving and Closing is also here.
|
|
|
|
It is also possible to load an .sf2 through drag & drop from your file manager into the Fluajho
|
|
window.
|
|
|
|
The option *[B] Ignore MIDI Bank and Program Messages* only allows instrument changes via the
|
|
graphical user interface. It ignores all messages coming in via the JACK Midi connection.
|
|
|
|
This is sometimes necessary if you are dealing with midi hardware, like keyboards, which send bank
|
|
and program changes at startup and break our settings. You can also activate this option as soon as
|
|
you have set all instruments, because a program change unfortunately happens faster than one would
|
|
think.
|
|
|
|
The option *[C] Play test sound after selecting a program* can be activated to hear some played
|
|
notes right choosing a different instrument through the program change dropdown [G]. The test signal
|
|
is *not* played when changing an instrument through an external midi signal.
|
|
|
|
|
|
Channels are numbered *[D] Channel N* . MIDI supports exactly 16 channels, there is no adjustment
|
|
possible. More channels of the same soundfont can be obtained by simply starting another Fluajho
|
|
instance. Next to the channel is a small rectangle that lights up if MIDI is coming in.
|
|
|
|
*Play Test [E]* plays some test notes after a click. This can be used even if option [C] is not
|
|
currently activated.
|
|
|
|
The current *[F] Bank* is always displayed as a number. You can choose them from the drop down
|
|
list. Only the banks, which actually exist in the current sf2 are listed.
|
|
|
|
The current *[G] Program* is the instrument. It is displayed with its MIDI number and actual name.
|
|
Only the programs present in the sf2 are displayed.+ However, the soundfonts are often wrong in
|
|
that they display more instruments than they actually have. In this case you will hear a more or
|
|
less random (existing) instrument instead.
|
|
|
|
|
|
If you run Fluajho under Session Management, as intended, tere is no internal way to *close* it.
|
|
If you use the function of your window manager like [X], Alt+F4 etc. the graphical user interface
|
|
is only hidden.
|
|
|
|
To really close Fluajho you can use Agordejo (New Session Manager). Here you can
|
|
also restore visibility by showing the GUI again.
|
|
|
|
The current visibility setting is saved. This is because you normally only spend a relatively short
|
|
time loading a soundfont. Afterwards, the window would only get in the way.
