making SID music sound the same on 8580 & 6581

  • hi, i am just starting out with using goattracker to make some c64 music, and i would like to make music so that it sounds the same (or as close as possible) regardless of if using a 8580 or 6581 chip


    please could anyone tell me, which sound parameters/effects of the SID chip i should avoid using in order so that the music sounds the same (or close!) on all SID chips?


    thanks!

    ps ... if it is a stupid idea to try to do that let me know :)
