So it's either: Low pass, or High Pass or Notch. Plus the bandpass or inverted bandpass from the same filter. |
All the "notch" is is the lowpass and highpass combined. If you treat the LP, BP, and HP as separate outputs of the filter, you could think of them as 3, especially since you can set the levels independently. A classic notch filter would be if you set LP and HP to the same level, but you certainly don't have to set it this way. You could set LP, BP, and HP to different levels (or modulate the levels!) to create all kinds of funky filter slopes, all from one filter.
For a series filter configuration, you're "limited" to Notch->Filter2 or BP->Filter2, but once again "notch" is just the post-mixer LP and HP levels mixed. So, Notch->Filter2 could be "LP->Filter2" or "HP->Filter2" or "some LP and more HP into filter 2" or what have you, based on the HP and LP mix levels.
You could even turn up LP, HP and BP all together and get an all-pass filter. One limitation is, you can't route all-pass thru filter 2.
You can also turn LP, HP, and BP all to zero and then you have a no-pass filter.
