Acrobatics Forbice (version 1.0.3 - 23/10/2012)

A stereo filtering module providing maximum tools for audio cutting and mangling,
whether they are drumloops, voice or instrument recordings or audio samples.
The full-stereo and flexible architecture allows complex configurations of parameters
and true musical interaction of envelope and filters with user audio input contents.

Two channels -12/-24/-36/-48 dB LowPass filter is driven dynamically through a fast
AHR envelope, keytracked and modulated by a synchronized/free running full-featured LFO.
Also available are high-pass resonant filtering, bitcrushing and distortion stages.
The effect unit features full VST & MIDI control and a flexible routing of signal
with additional balance, mix and dynamics fine-tune processing.

Tech notes:
32bit ultra-optimized code, zero latency, low filter phasing,
samplerate independent engine, all sample rates supported.
Each control is fully recordable and automatable in host.
Most knobs & switches receive external MIDI control changes.

Overview on controls (back):
--------------------------------------------------------------------------------------------------------------------------------------------------
	Keytracking		Keyboard action controls the opening of main filter
	Keytrack Action		Half or full action of keytracking on filter values
CC1	HPF Frequency		High Pass filter cut frequency
	HPF Resonance		High Pass filer resonance factor
	High Pass Filtering	Bypass or activates the HP filtering
	HPF Routing Kind	Chooses if HPF applies only on envelope input or on main signal too
	Test Loop		Activates/deactivates test audio loop (automatic off on preset change)
	Filter Emulation	Chooses between three different filter models: Ladder, Butterworth, Chebyshev
	LFO Shaping		Chooses between sine or triangle oscillator waveform
	LFO Synchronization	Host syncs LFO to host timing, free let the LFO free run
	AC POWER		Effect power switch simulator (act as a gate)
	Bit Crush Resolution	Chooses the number of bits for quantization of signal
	Bit Crushing		Bypass or activates the bitcrushing

Extra Controls infos:
--------------------------------------------------------------------------------------------------------------------------------------------------
	When "Keytrack" switch is ON:
	Filter openings are conditioned by the note played from the MIDI sequencer,
	where the knob position represents the top frequency playable
	(in order to use plug-in keytrack mode, you have to activate a dedicated
	MIDI track in your sequencer and assign the MIDI output to Forbice).
	You can additionally select "half" o "full" action on the KT action switch
	to regulate the amount of keytracking applied to the patch.
