OK, I could use some help in understanding & reducing some of the stuff in the Parametric EQ.
1:
Couldn't the 1st multiply be removed & just the Float result put into the 2nd mult.
2.
Would it be faster to Add a -1, or simply directly attach a -1 Float?
3.
Here, I replaced a Float Divide 40 with that Mult 0.025. Is my way faster?
4.
What does this do? In ASM, it gets rounded to 0.
5. In the EQ, the "Slow" EQ has alot of pre-calculations in green code... I'd assume that would be faster than all the calcs in Code like the "Fast" version.
cheers

I'll try my best..
1: Greens are only recalculated when a trigger/value change passes through so is't kind of irrelevant, I reckon it's this way as Stef can only remember pi and not 2*pi 😉
2: Neither Add/subract are faster, so this way is probably clearer
3: Divide is slower, in most cases it shouldn't matter with green code, but if you are going to be using large amounts of calculations it's probably better to use multiply..
4: Are you sure it's rounded to zero? It should be equal to 1e-12, This is an inaudible amount thet is added to the audio path to stop denormals. If you ever have a module with feedback something like this should be included.
5: The slow params take less cpu but do not have smooth transitions when controlled, and in some cases are unstable. You can use the fast params to adjust the controls, and when satisfied with the settings switch to slow params to save cpu..

Well, I imagine the OSM would be smaller with less maths.

Ah, that's a neat trick. But the ASM does seem to be 0:
thanks
