Do you have access to either a KR-55 or at least some decent samples that <br>
you could analyse? The frequencies of the six free-running oscillators <br>
stand out as fairly prominent spectral lines in the TR-808 cymbal and hi-hat <br>
sounds, (despite all the clipping and filtering that follows the <br>
oscillators!)<br></blockquote><div><br></div><div>Good idea, potentially - but I wouldn't expect these frequencies to be quite as visible in the audio from the Korgs, since they are ringmodulated in pairs rather than just added like on Rolands. :-) </div><div><br></div><div>/mr</div><div><br></div></div></div>
