+; FileMix (2010) for realtime Csound5 - by Arthur B. Hunkins
+;  requires MIDI device with 1-16(17) knobs/sliders; 1-4 files
+;  1-4 controls per file (amp, band-pass peak freq, peak gain, speed/freq)
+;  Quantity of knobs/sliders needed = number of files * number of parameters.
+;   An additional controller is optional Master volume.
+;  Files may be mono or stereo; can have different sample rates, may be a variety of
+;   uncompressed types including WAV and AIFF; also Ogg/Vorbis (with Sugar 0.86/
+;   Blueberry or later) but not MP3.
+;  They must be named soundin.1 (through soundin.4), and in the same folder as this file.

+; FileMixASC (2010) for realtime Csound5 - by Arthur B. Hunkins
+;  ASCII keyboard control (no MIDI); 1-4 files
+;  1-4 controls/parameters per file (amp, band-pass peak freq, peak gain, speed/freq)
+;  Files may be mono or stereo; can have different sample rates, may be a variety of

+;   Blueberry or later) but not MP3.
+;  They must be named soundin.1 (through soundin.4), and in the same folder as this file.

+#
+# version 1
+#
+#    Notes:
+#
+#    The four versions that comprise the FileMix utility series are:
+#    FileMix4, FileMix4ASC, FileMix and FileMixASC. FileMix4 and
+#    FileMix4ASC require 4 stereo soundfiles, while FileMix and
+#    FileMixASC can handle 1-4 mono or stereo soundfiles. The files
+#    can be of any sample rate and a variety of uncompressed formats
+#    including WAV and AIFF; also Ogg/Vorbis, but not MP3. The Ogg/
+#    Vorbis format is only possible when the Sugar version is later
+#    than 0.84, which excludes the XO-1 and SoaS Strawberry. The XO-1.5
+#    works fine with Ogg.
+#
+#    Actually, the ogg vorbis format (which is written by the Record
+#    activity) can be used by SoaS Strawberry (0.84) if libsndfile is
+#    updated. This can be done while connected to the internet by
+#    issuing the following commands in the Terminal:
+#      su <Enter>
+#      yum update libsndfile <Enter>
+#
+#    Students are encouraged to create their own soundfiles, especially
+#    to make their own nature soundscapes. (This is the primary intent
+#    behind these utilities. The four short "nature" files included here
+#    are abbreviated versions of those from the author's DUSK AT ST.
+#    FRANCIS SPRINGS [www.arthunkins.com].)
+#
+#    The natural vehicle for soundfile creation is the Record activity.
+#    This activity is fairly simple and straightforward; the only problem
+#    is that certain versions of it work poorly or not at all. The
+#    following versions of Record seem to work well or fairly well: v59
+#    (well) with the XO-1; v67 or v85/86 (fairly well) with XO-1.5; v64
+#    (well) with SoaS Strawberry; v66 (fairly well) with SoaS Blueberry,
+#    Mirabelle and later. (This is as of 9/2010.)
+#
+#    Soundfiles must be moved into the folder where this file resides,
+#    and be renamed soundin.1 through soundin.4.
+#
+#    Important: The controller must be attached AFTER boot, and BEFORE
+#    the version is selected. It is assumed that the controller is a USB
+#    device. The inexpensive Korg nanoKontrol is one appropriate
+#    controller choice; it can nicely handle either 8- or 9-slider
+#    renditions (but not those requiring more than 9 sliders). Choose
+#    Scene 4 on the Korg, and Channel "0" in the performance window.
+#
+#    It is also important, with all versions, to wait 3 to 5 seconds
+#    after pressing START, before moving any controls or pressing more
+#    buttons/keys. The utilities will not respond to these actions until
+#    after this time.
+#
+#    To facilitate performance of FileMix on the Korg nanoKontrol, its STOP
+#    button has been programmed as a Delay Start option (buttons on the
+#    device, by default, are not set to MIDI notes). It is conceivable
+#    that this feature could interfere with MIDI controller selection
+#    (Continuous Controller numbers). Solutions to this possible issue
+#    are discussed in the FileMix.txt document on the author's website.
+#    Other relevent items of interest may also be found in this document.  
+#
+#    On a few systems, e.g. the Intel Classmate PC, the specified sr
+#    (sample rate) of 44100 may not produce audio. Substitute a rate of
+#    48000 toward the beginning of each .csd file, using a text editor.
+#
+#    If you get audio glitching, open Sugar's Control Panel, and turn off
+#    Extreme power management (under Power) or Wireless radio (under
+#    Network). Stereo headphones (an inexpensive set will work fine) or
+#    external amplifier/speaker system are highly recommended.
+#
+#    The font display of this activity can be resized in csndsugui.py,
+#    using any text editor. Further instructions are found toward the
+#    beginning of csndsugui.py.
