Would degradation be a problem?  A decent quality mp3 might "sound" right,
but how would it go for data transfer stuff?

I'm still yet to get patches to transfer properly via audio - the most I've
got is about a quarter of a set, which is all that's on my poly at the
moment...

Does anyone know anything about the data-to-audio / audio-to-data method that
is used?  ie., do you think it would be possible to make up some program that
could analyse a wav file and extract the patch settings from it?  Could be a
first step to creating a reverse process whereby you could program all your
patches using virtual knobs on your computer, write these settings to a wav
file, then dump it to the poly?

i thought of that to... so i suggest to encode in the highest quality 
possible (what was it again? 360khz or something like that)since 15 
seconds of mp3 will not get infinitely big....
i havent tried it yet, but will in the near future. personally i have 
a lot to do the next two weeks and will only be reading the posts here 
(with the occasional replies, of course ;) )  
so you´ll have to wait a little longer...

hm, strange... it worked the first time i ever tried it - no problem 
at al. then, of course, i might just have been lucky...
i do it via an aux send on my mixing console - the monitor is down to 
silence this meeeeeeeauwouwerahawaououueeeeee, the bus with the 
soundcard is up so that the max peak is 0 db and the aux send is on 
full. the tape selector is set to low. dunno, maybe this will work for 
you too...

interesting idea.... no, i don´t know anything about that.....
except that if such a software was developed it would have to come 
with a complete poly 800 emulation since only some knobtweaking 
resulting in a wavefile will give you absolute no impression on how 
the patch you are currently editing will sound like..... it would 
(given the editor has no sound output) just be senseless 
"let´s-turn-this-one-this-time".
but, as usual, you´re welcome to start this project ;)

so long for now, 
christian

I know there's a program that does that for MC-202 patterns.  Someone 
reverse-engineered the signals in the tape dump...very interesting idea but 
it's not too convient.
