JAF Filter Collection

The Analog Filter Model Collection

This is a collection of analog modeled filters from the golden age of synthesizer technology.

We tried to emulate different well known filter models from famous manufacturers with all their quirks and none linear behaviours. We added saturation model, modulators and even implemented a powerful analog modeled unison oscillator, which makes this audio unit a highly creative noise generation giant.  

The audio unit is intended for manual parameter automation and does not include common parameter sequencers or such. 


What's this ???








The JAF Collection is an exciting set of digital modeled classic analog synthesizer filters (VCFs) . 

The emphasis of this collection of audio effects is analog sounding and optimized behavior with touchscreen usage, features that not many currently available apps and plugins do really offer. The apps and the included Audio Units are “universal”, so they work on iPhones and iPads the same way and also have basically the same appearance and functionality. 

Note: These apps are so-called “Audio Units” (aka plugins), which usually require hosting audio applications to operate. Although, they come with their own basic host applications,

The JAF Collection Filters can also act as a synthesizer module due to the fact, that there is an unison oscillator section (VCOs) built in for testing and for live performances. The analog modeled synthesizer has no advanced controls or modulators. It just runs the oscillators continuously and can be controlled by external MIDI messages to snap to MIDI pitches or being automated with the volume controller. 

The complete MIDI assignment is documented in the MIDI Implementation Chart for the JAF Collection.
