I attempted to download these with both lynx and links2, and was told both times 'please enable javascript', also that the download site was busy because Premium (paying) users were downloading. I doubt that wget can be made to download from sites requiring javascript.

I will try with Opera some time, but I don't have it set up to work with mplayer. Is this streaming ogg? If not, do you know how to post streaming ogg at 32KB/sec or so? Or would this not be good enough quality to learn anything?

I ran across 'grip' to create OGG files, also ffmpegtotheora (theora is ogg) and ripit and 'Ogg Vorbis Encoder 1.0b4 for Linux' and Cakewalk and crip. What program did you use and does it work with BL?

A friend is recording his LPs to aiff (which I think is uncompressed). I might try recording to ogg.

Your files are:
1.9MB, 605KB, 1.3MB, 2.9MB and 2.5MB
I download at about 6MB/hour. I might try listening at a friend's house where there is broadband.

Am I correct that you have played these files with OPL2 and OPL3 and XG (software synthesis) and recorded them to wav and then converted to ogg, which you uploaded to this free file-sharing site?

as promised; some recordings of FM synth the way it was -supposed- to
be done... in these tunes each voice of the OPL chips are controlled
directly... stereo/echo/reverb/polyphony and even the instrument
parameters themselves are all done manually... nothing is preset...

I will try this out as soon as I put together a computer that has a
working SB16 sound card, a working IDE controller, and a modem.
I am currently online via Toshiba laptop/pcmcia.

these are ogg vorbis files... you dont need a specific soundcard...
just one that works...


first a very old tune... composed just for the OPL2...
http://rapidshare.de/files/18539280/adlib_ticktock.ogg.html
the OPL2 is mono and has only 8 voices...

http://rapidshare.de/files/18538281/adlib_cheatengine.ogg.html
this one is also for the OPL2... with a little more interesting
instruments.. not sounding quite like general midis fm patches
anymore.

playmidi -f ? As opposed to playmidi -4 for the one below?
I will also try playmidi -f on the OPL3 file.

these werent/arent midi files... playmidi wasnt used... but you could
think of it that way... the opl3 does support 2operator mode just that
it has more options like stereo... that can be used in two op mode...
the above songs are mono and 2op only because thats all the opl2 can
do...


http://rapidshare.de/files/18534740/adlib_oldschool.ogg.html
now for the OPL3 ... a stereo chip with 18 voices and more waveform
options... 'reverb' was of course done manually... the width of the
variable width pulse used as the lead at the beginning and end can be
changed as the note is playing... not quite GMs domain...

http://rapidshare.de/files/18540187/adlib_encore.ogg.html
again OPL3... and the most complex of the tunes... so much so that the
artist said that they wouldnt ever try something like this again...
see if you can 'name the tune'....


and just for good measure (no pun intended) a demo of another
apparently obsolete chip... the yamaha XG...

http://rapidshare.de/files/18540947/yxg_xgtechno.zip.html

I think I have this chip in the Win98 laptop! It starts up with some
message about Yamaha XG Softsynth. I can try listening to your three
files with Windows/Yamaha. (Turns out the PCMCIA slot is okay, the
Winmodem 'cannot open port' so is probably dead).

softsynth is the software version of the XG... to be honest... its
what i used too.. an old copy of S-YXG70 that came included on the PC
version of final fantasy 7.... unfortunatly it only works in windows
9x... if anyone out there knows where to get an NT version im all ears
but i think this is the wrong list to ask this on...


How would I set up the Yamaha XG sound card to work in linux (after
shrinking Windows with Partition Resizer or Partition Manager)? If it
needs ALSA sound, would it be simpler to install SW10.2 (and will it fit
into 500MB without source code or compiler?)


I gave up on the sound chip in the Toshiba and Hitachi laptops (some cross
between MSS and SBPro for play and record) but got the video working
(similar config for both). This Win98 laptop has Neomagic video, which
might be a pain to set up for X but is not needed for playing with sound.

================================



I also just realized that the essolo1 PCI sound card in the Win98 desktop
played at full volume through some really cheap unpowered speakers, which
implies that my other card (in the linux computer with powered speakers
turned up full) has a dead amp on it.

depending on how the card is built you might be able to replace it...


the XG seems to be like a hybrid of directly programmable chips and
general midi... the file is zipped with both the .ogg and the .midi
file that was played to get the ogg... while technically the midi file
will play on anything it wont work right on anything other than the XG
due to the extended instructions XG has that general midi doesnt...
see how it does with the clavicorda keyboard...


PS my apologies for the 'buzz' in the background... the sblive that
was used for recording seems to have problems when its line-in is
connected to the line-out of other soundcards... seems very sensitive
to groundloops... even if the ground isnt connected...
