Not directly related but, thanks to Adam Szabo, I recently discovered Roland’s technique of using a tracking HPF set to the fundamental pitch of an oscillator. This all but eliminates the aliasing frequencies below the fundamental but still keeps the higher enharmonics created and, to my ears ...

Hi Martin,
well i'd say it's a matter of taste. Maybe if you like to have it less digital and more analogueish style it'll become an issue.
Depending on the input source this "extra dirt" sometimes can be annoying. But you're right, in case of wave shaping it's less important than in other effects ...

This is a proof of concept of REDUCING ALIASING OF NONLINEAR WAVESHAPING USING CONVOLUTION
I recently stumbled over that conference paper and implemented the method in my upcoming plug.
However i found it surprisingly efficient compared to the cost of CPU (well, at least if done in C++ )
So i mocked ...

It might be because with add primitive you can parallelize the adding. If you just use plain connections the resulting code is equivalent with: out=((a+b)+c)+d
With add primitives you can arrange the additions into a tree: out=(a+b)+(c+d)
processor can then execute (a+b) in parallel with (c+d ...

Hi Aron,
this is pretty cool
What exactly are you doing with Flowstone in that environment?

As usual very cool and perfectly coded stuff!
Thanks for sharing your work!

Martin already did the hard work for you:

You owe him a beer...

Some ideas for optimization...
One general ruel is to take everything out of the stream what's not needed.
E.g. all LFO's are running though not all are used (level = 0). You could e.g. add the option "Off" in the wave menu to switch them off.
One other thing i noticed is your DC filter. A SVF for ...

Ahh, here it is:


15 years on tour with that little baby

Ok, then a more "construction set" description...

Consider one of the ZDF filter modules as one biquad filter. The Q value is the resonance part of it.
To get a flat response ( = 0 resonance) from your biquad filter you'll need the values from the quoted function.
If you use one filter module you ...
