Popsicle is a Multi Effects Processor built around 2 independent stereo effects engines each having access to a total of 24 different effect algorithms. Effect engines can be used in series or parallel configuration or split between stereo channels where one is affecting the left channel while the other one is affecting the right channel respectively. Popsicle features a powerful XY Pad capable of controlling one or more fx parameters per axis. XY motion can be recorded and played back in sync with the host tempo allowing for highly dynamic effects. In addition, a advanced mode unlocks a fully featured mod-matrix with an additional LFO and Envelope Follower allowing for even more dynamic effect combinations and performances. Included Effects: - Lowpass Filter - Highpass Filter - Bandpass Filter - Morphing Filter - Formant Filter - Comb Filter - Echo - BPM Delay - Short Delay - Reverse Delay - Stutter - Chorus - Flanger - Phaser - Tremolo - Auto Pan - Vibrato - Bitcrush - Distortion - Fuzz - Pitch Shift - Plate Verb - Hall Verb - Mod Verb Supports: - Standalone - AUv3

TfxMod is a chorus / flanger effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). The delay line is identical to the delay line of the TfxEcho except its buffer length. 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 chorus / flanger unit. Features AudioUnit Extension Chorus Effect - Delay Time: From 1 ms to 40 ms - Feedback: 0% - Modulation width: From 0 ms to +/- 1 ms Flanger Effect - Modulation Mode: mode1, mode2, and mode3 - Delay Time: From 1 ms to 20 ms (mode1&2), From 1 ms to 13 ms (mode3) - Feedback: From 0 % to 100 % - Modulation width: From 0 ms to 39 ms (mode1), From 0 ms to 19 ms (mode2), From 0 ms to 12 ms (mode3) Common - Adjustable lowpass filter and high-pass filter. - Modulation rate: From 0.01 Hz to 10 Hz - LFO Frequency can be synced to the tempo provided by the host application. - LFO Waveform: Continuously variable from sine wave to triangle wave. - Stereo Width: LFO Phase offset from 0 degree to 180 degree. Host Application - Host application uses system audio input as an audio source and processed audio signal is routed to the system audio output.
