Fixed Filter Bank |

I start really to agree that such a module must return in the G2 just because its so impossible and over expensiv to patch such a thing on the G2..
I also dont see the NM1 Filterbank as so bad sounding anymore...its really not too bad in relation to the amount of bands...
However..here is a minimal version that just needs around 20% ! oh oh... :-/
It still nowhere as steep as the Nm1 version and has less bands...but..
duo some phase changes in the circuit it gives a quite nice exciter fx...
I tried to tweek it for reasonable sound quality..and being related to the Nm1 filterbank to become a module in the patch converter...
However..if anybody has better tweaks for such a thing bring it up..just..
It should stay below 25 %...

Wouldn't the approach described by Rob on his tutorial pages be cheaper? He describes a simple method for cascading filters. Or would this differ too much sonically?
This is a pic from his site showing the idea:

Thanks for trying it out G2Ian, I was typing with one hand and juggling my 3-months old in the other, so I couldn't do it myself _________________ Spinning at ~0.0000115740740741 Hz |

Has anyone of the Experts tryed to build a Filterbank with 16 bands and steep angles ?
VA load is NO point. ( space also )
( sorry, i was never into building filterbanks, and since i used my G2 no more for a long time i hope you got maybe allready one patched. )
Is it possible to patch something with sonic qualitis near to the one in the spectralis ? |

You can just expand Ian's one and then make the filters steeper and change the frequency settings to you likings. _________________ Jan
also .. could someone please turn down the thermostat a bit.

When you want to use control signals to dynamically alter the volumes you could do that yes, or use the Level/LevMult instead which probably is a bit cheaper.
When you just want static volumes you could chain another MixFader to the one already in the patch. _________________ Jan

Me no expert, but this is just a simple extension of Ians patch. No idea about the sonic qualities of the spectralis either. Let us know how it compares according to you.
edit: ah, I see Blue Hell proposed already what I patched up, well, at least you don't have to do it yourself then . It's no rocket science anyway, but nice to play with. Also nice to use a couple of morphs on several overlapping sets of bands, for nice effects with a few knob turns. Trying out on a laptop/with the demo now, so I am curious how this sounds on the real thing with some audio going trough...
