WoodScaper vs TfxEcho

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.

TfxEcho is an echo effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). BBD is used in various analog delay unit and is known for its warm and dark sound. The delay line uses fixed length buffer and an artificial clock to sample input signal in variable sampling rate. When the delay time is changed, the delay line can produce pitch change effect which is similar to the behavior of the BBD based analog delay unit. The delay line is inspired by BBD, but it is not emulation of the any particular BBD. Unlike the typical BBD based delay unit, frequency range of the delay line is not limited. The delay line is capable to capture signal in higher frequency up to about 22KHz. Features AudioUnit Extension - Delay Time: From 20 ms to 1200 ms - Feedback: From 0 % to 100 % - Adjustable lowpass filter and high-pass filter. - Modulation rate: From 0.01 Hz to 10 Hz - Modulation width: From 0 ms to +/- 10 ms - Delay time can be synced to tempo provided by the host application. Host Application Host application uses system audio input as an audio source and processed audio signal is routed to the system audio output.
