Here is easily one of the most amazing free modulation filters there are on this website, and I insist (INSIST, I SAY!) that everyone here get it and try it out!
If you are producing anything that requires textural modulation, you cannot go wrong with this plugin. It has really opened my eyes to a whole new approach of enrichment simply through the use of filtering. This plugin will demonstrate to you how filtering can be used to obtain effects that range from the definitive, to heavy modulation scapes such as flanging, phasing, delay and echo, wahs, panning, formant type vocoding, gating and tremelo...and all tempo synced...it is fantastic! You MUST check out the preset bank that comes with the download.
I think that coming across this plugin has made me truly understand just how little I new about, and appreciated, exactly what extensive filtering can do for you. Before this beauty, I would have been trying to modulate using several effects to acheive the same as can be done with this plugin alone, and yet, it's not some huge horiffic monster with a learning curve from hell.
I believe everyone who tries the Obertone Filterbank is going to appreciate this plugin tremendously, but most importantly, it serves, in my opinion, as a most esoteric expletive to the importance of attaining a surgical and familial understanding of the frequency spectrum.
I found out that the writer, Markus Feil, is presently at reFX. He updated the Obertone page, so for those who were asking, the plugin IS now available for downloading.
Now...lets see if we can get him to update this gem! I would GLADLY pay for a newer version if asked to do so...and so would you.
