ok - i'll do the update next week and also the fft stuff. i've been learning sage recently. it's really amazing. a big new gun to shoot at math problems....

for example, i could solve the energy normalization for a multipass butterworth filter (for scaling the cutoff frequency as function of the butterworth order and number of passes to normalize...

and we can also quickly plot stuff - even online: https://sagecell.sagemath.org/?z=eJyVkMFOwzAQRO_-ilU41A4ObsIBCSmnKsfkE0Cm2aaGODYbtzR8PU4KAlUcwBePx9Kb0bS4g-0huN2ucWR1b96ReCOhFvcM4umghFyNrxR4IRaHMBxoAN498KxQtchyEVWueJE2QjDWRiIOSN30O7GKRG_STlureQ1ZxBeqEYo3X574FNnyA9eQi3Q0A4_P1Bs1p_woElm5qhg7auLJlAhm9amZW69nVZ-V98sNcAXuiDRq63uEU3SCA6tfEDSM1rmwRwLfu8A2c80oblt-uY8EfpK5nHOE5NNZ1kKC83prwlSub-4kbF3vqFw99QdcSTgafEMqk7AnxOcxkQv80TszhLH0XrDqO_Byvn8FErYx7w-Bm7hs9QFr8pmx&lang=sage

finally i have found some use for the gamma function. haha! ```cpp template T rsPrototypeDesigner::butterworthEnergy(int N, int M) { T k = T(0.5)/N; return T(PI*tgamma(M-k) / (N*tgamma(M)*tgamma(1-k)*sin(k*PI))); // The formula...

nice - i like how you arranged the trisaw waveform parameters - two rows for upward and downward halfwave parameters. and also the icons for the shape parameters. no numeric...

> I wonder if you could make 0 sigmoid be a sine and 1 sigmoid approach a square. hmm...did you try my sine-to-square patch in liberty? > another thing that...

TriSawToSine.xml - a ToolChain preset. tweak "Boost"

wtf...yes... i just verified...your directory is missing a lot more patches when did you pull the last time?

oh - no - the "Presets" repo is obsolete. i have now created a new repo with all support files (presets, samples and more): https://github.com/RobinSchmidt/RS-MET-Data

as said - put it in you app-data folder and rename it appropriately (remove the "-Data" from the dir name)
