Tone2 BiFilter2


Tone2 ® is proud to present BiFilter2, a high-end quality stereo filter module. BiFilter2 drastically extends the 'filter plug-in' concept to provide today's creative musicians with an extremely powerful multi-effect tool.

Years of research were necessary  to create the ultimate filter module for today's musicians. We are certain that you will find it to be a useful and powerful tool in your musical arsenal and have a lot of fun making music with BiFilter2!

BiFilter2 offers dual multimode filters with 47 unique and different sounding filter types. 8 additional distortion types, FM, AM, wave shaping and lo-fi effects create new and unheared sounds.

A high precision display shows the frequency response of the filter in realtime. This makes BiFilter2 very easy to use and understand.

BiFilter2 features:

  • 47 unique, different sounding filter types
  • 8 warm sounding distortion types
  • FM, AM, Waveshaping, bit crushing, resampling, comb filtering, vocal filtering, equalizing, reverbaration
  • Excellent value for money
  • High precision, real time frequency response display
  • Paramtere smooting, click-free knob movements
  • High-end quality filter algorithms, anti-aliasing, oversampling
  • True stereo architecture, works in all known sample rates
  • Easy to use interface
  • 100 presets
  • Midi and automation support
  • High performance

Distortion types:

  • Off – When this mode is selected, the distortion module will be bypassed.
  • Volume – Drive controls the volume of the signal.
  • Tube Amp – A 'soft knee' saturated distortion.
  • Transistor – An asymmetric 'soft knee' distortion.
  • Presence – A 'soft knee' saturated distortion with falloff at higher levels.
  • Hard Clip – A 'hard knee' clipping distortion.
  • Bitcrush – This distortion type reduces the bit rate of the audio to 'lo-fi'.
  • Waveshape – This distortion type adds additional harmonics by using round nonlinear amplification of the audio signal.
  • Pow2 – This distortion type adds additional harmonics by using edged nonlinear amplification of the audio signal. It is similar to exciters.
