[Linuxsampler-devel] LinuxSampler GUI spec.

[Rui N. C. <rn...@rn...>]

Hi all,

Here goes, at least under my point of view 8)


Preliminar specification for the LinuxSampler GUI application
-------------------------------------------------------------

According to current LSCP document draft (v.04), and the corresponding
iblscp implementation, the following notes apply as proposed requirements
for the primordial LinuxSampler GUI application.


a)  Each sampler channel maps to one strip on the main GUI control panel,
    whithin the main application window.

b)  Sampler channel strips may be stacked on either a vertical (like a
    mixing desk) or horizontal layout (like a studio rack).

c)  Channel strips are added or removed at will.

d)  Each sampler channel strip shall have the following GUI controls:

 1. Engine        : string  <engine-name>   : option list.

 2. Instrument    : string  <filename>      : button; fileopen dialog.

 3. MIDI Type     : "alsa"                  : option list.

 4. MIDI Port     : string  <midi-port>     : edit box.

 5. MIDI Channel  : int     <midi-channel>  : option list.

 6. Audio Type    : "alsa" | "jack"         : option list.

 7. Audio Channel : int     <audio-channel> : edit spinbox.

 8. Volume        : float   <volume>        : knob/slider; edit spinbox.

 9. Voice Count   : int                     : display.

10. Stream Usage  : int[]                   : display; chart.

11. Reset         :                         : button.


e)  The complete session state might be saved and loaded from the local
    file system, as plain LSCP script documents.

f)  The application setup options dialog include the linuxsampler server
    hostname and port specification with option to auto-start the server
locally (localhost), where the corresponding startup command-line may be
user editable.

g)  The main application window may follow the SDI model, with regular
    menu, tool and status bars. The proposed initial menu hierarchy:

    File

        New             Start a new session state from scratch.
        Open...         Load a session from an existing LSCP file.
        Save            Save current state to a LSCP file.
        Save As...      Save current state with an alternate name.
        -               -
        Quit            Quit application.

    Edit

        Add Channel     Add a new channel strip to current session.
        Remove Channel  Remove selected channel strip from session.
        -               -
        Reset Channel   Reset currently selected sampler channel.

    View

        Show Menubar    Show/Hide the main window menubar.
        Show Toolbar    Show/Hide the main window button toolbar.
        Show Statusbar  Show/Hide the main window statusbar.
        -               -
        Show Messages   Show/Hide the messages log window (debug).
        -               -
        Options...      General options setup dialog.

    Help

        About...        Self-credits show off.


Think this is enough, for the time being.

Yet again, another important question remains, which deals with the
"official" application name. My proposals goes to, in strict biased
descending order of preference:

    qsampler
    qls
    qlinuxsampler
    lsgui
    linuxsamplergui

Of course, those "q" prefixes comes from my reliance to Qt :)

So, make up your minds, ppl.

Cheers.
