Hi Robin,
When I saw your shelving based MB compressor, I also set out to make a
generic N band and M channel version of it. :)
I ran into the same problem, and came up with this solution:
https://github.com/magnetophon/faustExperiments/blob/shelfComp/N_band_Compressor_N_chan.dsp#L47
Hope that helps.
Is your WIP also online already?
Cheers,
Bart.

Thanks for the confirmation that what I'm currently doing is not far
off
the beaten track. Similar concepts are also in filters.lib.
The actual use-case is to directly "pipe" the output of the analyzer
into a custom filter-stage:
```
_ :< bus(2) : (an.analyzer (6, freqs), _) : filters (freqs);
```
This works with for a **fixed** number of N bands, which defines the
number of gain parameters as M = N+1:
```
filters(fq, g1, g2, g3,..,gM) = _;
```
I would however prefer a generic implementation, that works for any
number of N > 0 bands, as explained at
https://gist.github.com/x42/eeb2aa9f9cc4a9083fb2cf2d86645c9a#file-mcomp-dsp-L43-L54
I'm not sure if this is possible in FAUST. But since it is trivial in
C/C++ it probably is and I just don't see it.
Cheers!
