I can provide the tape assembler code to you if you would be interested in looking at it. But honestly, why?

 Subject: [korgpolyex] Demodulating and Encoding the Audio/Tape Data
   
    Hi,

Does anyone know if the encoding scheme for the audio/"Tape" program or sequence data is publicly known? I recently pulled out my Poly800 for tinkering and modding, and I was thinking I might try to figure it out if nobody's done so already. 

Thanks.
