WoodScaper combines into one unit the 4 classic guitar effects : phaser, chorus/flanger, wah-wah and tremelo. Besides the familiar controls each effect has some extra not-so-commonly-found options. The 4 effects can be routed in series (pedalboard mode), parallel (DAW mode) or some combinations of those modes. Panning or the Stereo control can create stereo sounds from a mono input source. WoodScaper is both stand-alone and an AUv3 effect. - All LFO’s can be set to different waveforms : Sine, Square, Saw Up, Saw Down, Triangle. - All LFO frequencies can be set to a bar fraction (1/4, 1/8 , …) of the BPM or can be set free to a specific rate (independent from the BPM). - All LFO phases can be reset with a button. - All effects have an On/Off (parallel routing) or On/Bypass (serial routing) switch like on a pedalboard. The switches can be toggled by Midi CC’s. - Phaser has settings for number of poles, frequency range and modulation flavour. - Phaser has second LFO to modulate filter Q. - Chorus has feedback, HighPass, LowPass and Saturation. - Wah-wah control can be LFO, Envelope, Envelope + LFO, side chain, Midi note velocity or Midi CC 1 (mod wheel). - Wah Envelope has Attack, Release and Threshold or Sensitivity controls. - Wah can go up or down. - Wah filter type and Q can be set. - Tremolo has 3 types : Amplitude, Ring or Harmonic. - Harmonic Tremolo has cross-over frequency control. - Tremolo has a Threshold control to have more tremolo when the signal increases. - Tremolo has “Biased Tremolo” mode to get more tremolo when the signal decreases. - Has a global Input and Output Gain control. - Has 2 extra LFO’s to modulate most parameters (rates, depths, …) - Modulation LFO’s have their own slew rate control and a random mode. - Presets can be stored in iCloud Drive (makes them available on all your devices). - Presets can be switched with Midi Program Changes or a Midi CC (up or down) - Major controls can be set with Midi CC messages.
