I was talking about the number of<br>steps in a filter cutoff parameter - if you only have 7 bits in the filter cutoff setting<br>then you can only select 127 discrete cutoff frequencies. If you overdrive the filter<br>emphasis then it should turn into something close to a sinewave oscillator at the<br>frequency of the cutoff - the steps in the frequencies become audible which was a<br>ongoing complaint against these systems. The issue is that if you want to detune<br>the filter oscillating frequencies by a 0.1 HZ to get some phasing then you are out<br>of luck since the cutoff steps are too big. The same is true if you want to use this<br>filter as an extra oscillator (something that a lot of people did on the big synths to<br>get hammond sounds) then it doesn't tune that well,especially at the higher <br>frequencies where the filter was used as if it were another drawbar.<br><br>It doesn't mean the synth will not sound good, there are just some things that it<br>will not be able to do.<br><br>Regards, nick.<br> <br /><hr />Hotmail: Trusted email with Microsoft’s powerful SPAM protection. <a href='https://signup.live.com/signup.aspx?id=60969' target='_new'>Sign up now.</a></body>
