Flame Black Filterbank is an analog moving resonance filter bank. 

The module is based on the Flame Curves and combines its most important functions in a more compact format. As a result, the individual outputs for the filter channels no longer found a place on the front panel. 

The filterbank includes twelve-channel and a pattern player programmable via a software editor. You can use a freeware "Curves editor software" (Win/Mac) for setup and user pattern editing. The module needs a clock to run in pattern-mode. It also features a reset input to set the sequence back to the first step. The memory in the module can save up to 99 patterns. The active pattern can be seen on the display and selected thanks to two buttons. 

When the Black Filterbank is in sequencer mode, the Envelope potentiometer controls the AR envelope, the Variation knob adds random velocity and release, and the Fill potentiometer controls the level of all the channels.
In manual mode, when the sequencer is off, you can select different filter-types with the Variation potentiometer: allpass, lowpass, bandpass 1-3 and highpass. Thanks to the Fill knob it is possible to sweep through the twelve filter bands. The Envelope knob smoothes the sweep by activating a second band next to the selected filter band. Thus the change from one band to another is not so abrupt.
It is also possible to play the twelve filters via MIDI like a drum module, thanks to the supplied MIDI to minijack cable. It even reacts to velocity.

There are several CV inputs for controlling Envelope, Variation and Fill parameters as well as the pattern number.
