make att-rel calculation with [fexpr~] instead of a subpatch with block 2
fine-tuned all params (with C1 from Waves as reference)
cpu-optimized (use less tilde classes); changed fontsize 7 -> 9
put DSP part into own abstraction (for reusability)
use abstraction for DSP part
started working on r4mbc
added r4mbc
added 4-band frequency splitter
worked some more on the frequency band splitting gui
netpd-ized frequency splitter GUI (freq1)
netpd-ized frequency splitter GUI (freq2+3)
GUI layout of single band defined and created
abstracted gui stuff away -> r4mbc-sbcg.pd
finished gui abstraction
add all gui instances; added solo logic
basically working / without finish
stole default attack and release times from C4
finalized GUI (xfreq display and other stuff)
switched back from fexpr~ to reblocked vcf~ based att-rel algorithm

the fexpr~ formula is way too CPU expensive (why?)
