ChannnelStrip is a modeled tube preamp with 3 band EQ and a simple oscilloscope available as AUV3 and standalone app. Controlling dynamics with saturation is an often overlooked technique in music production. ChannelStrip is intended as an end-of-chain effect giving you smooth modeled tube saturation combined with an oscilloscope to monitor how the waveform is compressed. The integrated 3-band equalizer will furthermore help you apply gentle, unobtrusive tone-shaping. Even as a simple distortion effect or equalizer, ChannelStrip will make a great addition to your FX collection. Features: - Modeled tube saturation with character control - Gentle 3-band equalizer - Oscilloscope - Adjustable oversampling factor (WARNING: uses a lot of resources on higher settings and may cause audio dropouts)
