1) General questions:
Q I can't save in .XYZ format even though Awave claim to support it!
A Not all formats can store _all_ types of data. Ex: only very few
formats support saving whole bank files while most formats (supported
by Awave) supports saving single waveforms. What type of data you are
trying to save is determined by what kind of 'node' or 'item' in the
tree view list you have selected. See 'File Formats' in the program
help file and look at the export formats list for info about what
formats support what data types.
Q I try to load, audition or play this really huge file, but it takes a
very, very long time or the program just exits with an out-of-memory
message...
A Awave is currently limited to working only with files it can fit into
memory. To play huge files you may need a huge amount of physical RAM.
This is especially true for large MPEG audio files (BTW, the MPEG de-
compressor is not very optimized at all so don't even expect a 1/10th
of the speed of real time decompressors, e.g. XingSound).
Q The AudioPlayer doesn't work. It sounds really strange, or things even
locks up when I try to play certain, but not all, waveforms.
A Try dechecking the 'Device can handle arbitrary playback rates' box in
the Options->Program->AudioPlayer property tab (this can be necessay
because a few buggy audio drivers report that they can do things which
in fact, they can not).
Q Why don't you make a Machintosh version?
A With Softwindows 95 you can in fact run Awave on a Power Mac. For a
'native' version, see the next Q.
Q Why don't you make a DOS/OS2/Linux/Unix/Amiga/Atari version?
A Because I don't have the time or the motivation.
If there's enough people interrested interest (read "I'd register if
only you'd do an"), I might be persuaded to do a command line version,
stripped of the user interface and all editing functions...
Q Is there a batch convert function?
A Sort of; you can open multiple files (in the standard Windows fashion,
hold down Ctrl or Shift while selecting files) and then save all items
by using the 'Save all in multiple files...'function on the File menu.
This will save all instruments, or, all waveforms, depending on the
capabilities of the output format you choose. The items will be saved
as files with the name you choose, the last two characters in the
filename beeing used as an increasing index. Ex: Myfile00.Wav
Q When saving stereo data to a format that only support mono waveforms
or when doing an SDS transfer, how do I specify which channel of the
stero data should be used?
A In theese situation Awave always automatically merges the channels by
an 'arithmetic average' algorithm. However, you can use the waveform
item->Properties->Editor->Process wizard to specifically convert the
data to mono before you save it; there you can choose between 'average
of channels', 'left channel only' or 'right channel only' algorithms.
Q My synth doesn't support bidirectional or reverse looping, what can I
do about wavforms that uses it?
A Try:'wavform item->Properties->Editor->Process->Convert bidir into fwd
loop' or ->'Convert reverse into forward', should do the trick.
Q How do I unistall Awave and remove all the file type associations?
A Run awave, then Options->Program->Uninstall. Or, under Windows 95, you
can use the Windows 95 Control Panel's Install/Uninstall feature.
Q Where is all the audio processing functions listed in the help file for
the Audio precessing wizard? I only see a few of them!
A Some of them are only applicable to some sorts of data (like 'convert
mono to stereo' is only meaningfull for mono data) while other is only
implemented for some data types (like remove silence only works on mono
data) and finally, many of the functions requires you to select a range
in the waveform first. To do that,in the wavform properties editor tab,
press down a mousebutton over the waveform, drag with the mouse and
release the button. To unselect all, just click on the waveform again.
Q I can't move the position bar in the AudioPlayer!
A True, the |<| and |>| buttons are not working. But you can 'drag' the
bar (press down mouse button on the [] and move the mouse) booth when
playing and when its stopped.
Q For some synthesizers formats, Awave can only read 'disk images', why
can't it read the disks directly?
A Because they are not in FAT compatible format and thus are not readable
by the OS. This means that it would require some serious lowlevel
reprogramming of the floppy disk controller in order to read them.While
this is possible under DOS and perhaps under Win3.1, it is far more
difficult under Win95, not to speak of under Win NT, requiring (three
different) custom ring 0 device drivers (for the three resp. OS's).This
is not a project I care to embark upon... There are Shareware/Freeware
DOS programs for the resp. synthesizers that you can use to make disk
images instead.
Q How do I do to 'hear' the loop in the loop point editor?
A First enable auditioning. Backin the loop point editor,press the'Apply'
button to update the loop point. Then play it on your keyboard! If you
don't have an external midi keyboard and are using Awaves 'virtual
keyboard' then you'll have to use some other 'virtual keyboard' program
since Awave's doesn't work in the property sheet boxes (you need the
keyboard for typing in numbers there!). If you don't have one of the
supported wavetable cards, you may use Awaves 'Audio Player synth' but
beware that, due to interpolation artifacts, the loop point may sound
wrong (pops and cracks) if you do not play it at the midi 'root key'.
Q I'd like to be able to add a few audio file format conversion functions
to my commercial softwares,is it possible to license parts of the Awave
code from you?
A Yes it is, for more information look at my www page:

2) Problems under Windows 3.1:
Q Program complains about not being able to load COMCTL32.DLL when I try
to start it.
A You must have a Win32s version that supports the common controls
introduced in Windows 95.When this was written,this means Win32s v1.3.
Look in the WIN32S.INI file in the ...\WINDOWS\SYSTEM directory to
determine what version of Win32s you have. If you need an update you
can get it from Microsoft, or, you can dowload it from my WWW-page.
Q When I select the 'AudioPlayer', the 'Clipboard', or the 'MidiSDSDump'
virtual export format(s) in the Save as dialog, it complains about
'invalid filename' under Windows 3.1 + Win32s.
A That's right, it is an invalid name under the old 8.3 FAT.
Instead use the equivalent Edit menu commands.
Q The Midi SDS transfer and/or the auditioning stuff doesn't work.
A No. For some strange reason 32bit multimedia callbacks doesn't work on
a few Win32s systems, Sorry...
Q This automatic file association stuff doesn't seem to work.
A No. It is disabled under Win32s becaus
