Hi list!<br><br>I would like to open a thread about drum synthesis<br><br>I'm trying to make a tr909 emulator with an interface made with <a href="http://www.processing.org">processing</a> communicated with pd via OSC.<br>
I would like to make drum synthesis on pd based on chapters from fabulous sound-on-sound "synth secrets".<br>I'm not an expert on drum synthesis, so I'm making this work in order to learn about that. I know there is really expert sound designers on this community and I would thank a lot their help.<br>
Now, I'm trying to emulate a bass drum. I've take this scheme as example: <a href="http://www.soundonsound.com/sos/Feb02/images/fig13tr909bd.l.gif">http://www.soundonsound.com/sos/Feb02/images/fig13tr909bd.l.gif</a><br>
But I don't know how important for the final sound is the block VCO (sawtooth wave) + Waveshaping, instead of a simple sine oscillator. In synth secrets articles says:<br><br><font face="arial,helvetica">"The output from the oscillator then passes
through a waveshaper. This removes almost all the overtones,
transforming the sawtooth into something very close to a sine wave."<br><br>Another doubt is how accent has influence on amplitude envelope attack and decay, what's the range of pitch sweep (from 400 to 40-80 Hz?) and its envelope decay value (200msg?).<br>
And, finally I'm thinking about replaced noise generator + pulse generator with the trick used by roman haefeli on his 808bass (<a href="http://lists.puredata.info/pipermail/pd-list/2006-04/037663.html">http://lists.puredata.info/pipermail/pd-list/2006-04/037663.html</a>).<br>
<br>Any suggestion or reference???<br><br>Thanks!</font><br><br clear="all"><br>-- <br>Raul Diaz Poblete<br>*************************<br><a href="mailto:raul.lete@gmail.com">raul.lete@gmail.com</a><br>Barcelona [Spain]
