PLEASE NOTE: This is a AUv3 plugin, use it with a compatible host App. GSi ECHO B2 is the digital recreation of a particular unit of Binson Echorec mod. T5E that, despite being more than 50 years old, still has its original tubes and has had very little service in the last 30 years. We don't know how this unit sounded when it was new, but this is how it sounds today, in 2022. The plugin features all controls found on the original unit, plus 4 extra knobs for adjusting the alignment of each head (aka Azimuth on tape machines), one extra knob to slow down the drum motor up to half the normal speed (to obtain doubled delay times) and one last knob to adjust the level of audible circuit hiss. All parameters can be Midi controllable. All Midi CC numbers can be freely assigned. Works with all major AUv3 hosts, including Camelot, AUM and Garage Band. Can be used standalone with an external audio interface.
