Hi all,

Always in search of ways to make fat distorted filter sounds, while maintaining a 'smooth' response, i.e. avoiding the rythmic choking "WUB-wub-WUB-wub" sound you get when you send detuned oscs through distortion circuits.

Here's a couple of ideas -

1. The patch uses a HPF before the main distortion filter to remove the fundamental, and then uses a hard-sync'd sine osc to mix the fundamental back in after the distortion, so you get a smoother response when you sweep the filter down to low cutoff fc's.

2. Instead of detuned oscs, it uses a pair of pitch shifters after the distortion to generate the fat detuned sound, which avoids the problem of sending detuned oscs through a distortion circuit. Includes controls for detune amount & detune level, which also adds stereo separation.

Panel controls are assigned, but no variations. Enjoy!

Nice, Dave. You can really hear this technique working when you make the release time longer on page C2. Like you say, very smooth. Here's another earlier technique...

Yeah, that's some smooth distortion alright! Two thumbs up! Very Happy

I'm just wondering - how come the sine osc is hard synced to the saw?

Thanks! About the sine osc, it is hard sync'd to the saw osc to assure that it always has the correct phase relationship to the saw. Simply tuning the two oscs to the same frequency does not assure that they will always be in phase.

Why? An odd thing about the NM (and the G2? Anybody know for sure yet?) is that every time you load a given patch, the oscs are set to some random phase relationship. This doesn't matter at all when you are purposely detuning the oscs, but if you want multiple oscs to play at exactly the same frequency and always be in phase, you need to use hard sync. Otherwise, the oscs may be out of phase the next time you load the patch, and it may sound completely different. BTW - this tip is especially important when making bass sounds!

Ahhh I understand. I've noticed the same thing with other synths (like the DSI Evolver) when the oscs are tuned to the exact same interval. Each note press sounds different as the phases are different.

Thanks for the sync tip!
