Ohm Force: Frohmage
A free and completely unique type of low pass filter.
Ohm Force was founded in 2000 by a couple of friends who were well-versed with digital music, and freshly graduated from engineering school. They had an ambitious goal in mind: to create an online collaborative DAW so that people all over the world could make music together. It did not take long to realise how complex a project this was, but far from surrendering, they decided to pursue their dream on a longer-term basis.
Whether you want to emphasise or attenuate some frequencies, or brighten, colourise, or dirty any source lacking character, Frohmage will assist you in many circumstances. Despite its deceptively simple interface, the possibilities are tremendous and you will have a lot of fun working with it. This multi-band resonant filter has fine controls over its low-pass and bandpasses for up to 15 additional bands, as well as built-in distortion with two routing schemes and delay stages on each band for unique phasing-like effects.
