Changes in Icarus v3.2
- New filters:
- LP Ladder 6dB: This is a 6dB lowpass Ladder filter with self-oscillation. It sounds analog and uses 0-delay technology.
- LP Ladder 12dB: This is a 12 dB lowpass Ladder filter with self-oscillation. It sounds analog and uses 0-delay technology.
- BP Ladder: This is a bandpass Ladder filter with self-oscillation. It sounds analog and uses 0-delay technology.
- BP MS-20 12dB: A bandpas filter with self-oscillation. It sounds analog and uses 0-delay technology.
- HP Digital 24dB: This is very a precise digital highpass filter.
- HP MS-20 12dB: A highphass filter with self-oscillation. It sounds analog and uses 0-delay technology.
- Phaser 3x +: Analog 6-stage phaser with positive feedback.
- Phaser 5x +: Analog 10-stage phaser with positive feedback.
- Phaser 2x -: Analog 4-stage phaser with negative feedback.
- Phaser 4x -: Analog 8-stage phaser with negative feedback.
- Formant 1x: Analog formant filter with soft saturation.
- Formant 2x: Analog formant filter with two peaks and soft saturation.
- Formant 3x: Analog formant filter with three peaks and soft saturation.
- Formant 4x: Analog formant filter with four peaks and soft saturation.
- New effects:
- Ring Modulation: You can find this new effect under the ‘Frequency shifting’ menu. It comes with a Damp control for a warmer sound.
- Amplitude Modulation: You can find this new effect under the ‘Frequency shifting’ menu. It has a more extreme sound than Ring Modulation. It works best for effects, percussive sounds and drums.
- Weaver Shifter: You can find this new effect under the ‘Frequency shifting’ menu. It works best for effects, percussive sounds and drums.
- New additive synthesis modes:
- Add Disharm 4: Plays 4 oscillators with a disharmonic relationship. You can use the ‘spread’ knob to control the type and level of detuning.
- Add Disharm 8: Plays 8 oscillators with a disharmonic relationship. You can use the ‘spread’ knob to control the type and level of detuning.
- Add Disharm 16: Plays 16 oscillators with a disharmonic relationship. You can use the ‘spread’ knob to control the type and level of detuning.
- Add St Dish 4: Plays 4 stereo oscillators with a disharmonic relationship. You can use the ‘spread’ knob to control the type and level of detuning.
- Add St Dish 8: Plays 8 stereo oscillators with a disharmonic relationship. You can use the ‘spread’ knob to control the type and level of detuning.
- Add St Dish 16: Plays 16 stereo oscillators with a disharmonic relationship. You can use the ‘spread’ knob to control the type and level of detuning.
- New GUI features:
- An XY crosshair is shown when you click with your mouse inside the EQ display.
- An XY crosshair is shown when you click with your mouse inside the filter display.
- New “Metal opaque” skin for the user interface.
- It is now possible to record filter cutoff and resonace with the filter XY-pad.
- New XY-pad for the waveform display:
- The XY-pad controls are available when you click and move your mouse within the wavefrom display. They add a new dimention of dynamic expression as you can now manipulate 2 parameters at the same time.
- Context-sensitive help appears as soon as you move your mouse.
- In wavetable mode the X-axis is assigned to the to the morph parameter. The Y-axis is assigned to the wavetable position.
- In granular mode the X-axis is assigned to start position. The Y-axis is assigned to the grain size.
- In sample mode the X-axis is assigned to start position.
- If you play back a single waveform the X-axis is assigned to the to the morph parameter.
- Various enhancements to sound quality and more.
Available in VST3 and AU plugin formats, Icarus 3 is priced €149 EUR / $169 USD at the Tone2 store and from distributors such as AudioDeluxe and Best Service.
