Filtoizza is multitrack filtering effect.

Here is the scheme showing how it works with signal [per track]:

Here is the scheme showing how it works with signal [whole machine]:

Parameters' Prefixes:

• G-... : Global. These are Global Volume [per machine], ADSsR (as envelope) & LFO (as gapper) [per track]
• F-... : Filter. These are base filter parameters
• FF-... : Filter Frequency modifiers
• FQ-... : Filter Q modifiers

ADSsR Parameters:

• ADSsR-A : Attack - Time in ticks/32
• ADSsR-D : Decay - Time in ticks/16
• ADSsR-S : Sustain - Time in ticks/16 or Infinity
• ADSsR-s : Sustain Level - Level in percent of Max
• ADSsR-R : Release - Time in ticks/16
• ADSsR-M : Mod - Multiplier

LFO Parameters:

• LFO-WS : WaveShape selection for LFO
• LFO-F : Frequency in cycles per tick/16
• LFO-RP : Reset Phase - Used when RoT=Yes, in radians (0,2PI)
• LFO-RoT : Reset On Trigger - Resets LFO on Global Trigger
• LFO-M : Mod - Multiplier
• LFO-A,D,S,s,R : Same as in ADSsR

LFO Wave types:

Simple
• Sine -
• Saw -
• Triangle -
• Square -
• FastSine -
  This is approximation of sine, so it's not so smooth as normal sine, but is a little faster.

Mixed (added)
• Sine + Saw
• Sine + Triangle
• Sine + Square
• Sine + FastSine
• Saw + Triangle
• Saw + Square
• Saw + FastSine
• Triangle + Square
• Triangle + FastSine
• Square + FastSine

Amplitude modulated (multiplied)
• Sine * Saw
• Sine * Triangle
• Sine * Square
• Sine * FastSine
• Saw * Triangle
• Saw * Square
• Saw * FastSine
• Triangle * Square
• Triangle * FastSine
• Square * FastSine

Attribute Trigger-OFF ACTION tells machine what to do, if TriggerOff event happened:

• 0. Does nothing. Just plays note as long, as ADSR is set to.
• 1. If Decay wasn't performing yet, jumps to Decay sequence.
• 2. If Sustain wasn't performed yet, jumps to Sustain sequence.
• 3. If Release wasn't performed yet, jumps to Release sequence.
• 4. Just cuts the note.

Few notes:

• Note, that you HAVE TO have patterns to hear anything, because this effect has to be TRIGGERED to play (and this must be done for every track!)
• Parameter F-Gain works only for filters Peaking, LoShelf & HiShelf
• If you experience clicks - try turning off F-RoT option, as it resets filter everytime trigger comes.
• Parameter 'Instant' sets (when 'Yes') all the parameters jump instanty to their destination value when machine is not playing. This is useful, if you want to prepare parameters before machine starts playing. If set to 'No', all the parameters are going to their destinations, but only when playing! This means, that if there's slide in frequency for example, and sound lasts for 1 tick, and then is 3 ticks of silence and then second sound lasting 1 tick, freq will go during this first tick, then will stop and wait during 3 ticks of silence, and then continue to slide during second tick of sound. If you want to prevent this, use 'Yes' in parameter 'Instant'.
• All parameters are inertialized, mostly by blending 0.5:0.5.
• Some filter configurations (Type+Freq+Q) happen to be unstable.
• It is based on Noizza Synth
• It can handle from 1 to 8 tracks, but be careful - it kills CPU :(
