ECHO B2 vs spectwhirl

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.

"bells and whistles, literally" spectwhirl is a hybrid spectral audio effect. It can extract and rearrange sinewave components from input signal to make new sound textures and bell-like sounds. * input sound is converted to sinewave components that are divided into 4 groups: harmonic, inharmonic, 12-edo and other * each component is fed into a delay line with feedback * there is a group of frequency shifter and sample-and-hold effects before and after delay lines * each set of sinewave components can be filtered * all the parameters can be instantly automated with gesture recording !!! Please note that this effect consumes much CPU and requires a modern device. ====================== Quick Start: Top row of controls enables different parts of user interface: scenes editor ("scene"), controls switch ("edit") and "zoom" controls When "edit" is switch on, you can show or hide various controls (marked as "ctrl") and switch gesture recording automation for some of them (marked with ">") Main control surface displays sonogram with tracked elements. Colors are set accordingly to the group they are assigned (red-orange-green-blue are for harmonic, inharmonic, 12-edo and others). Each "lane" contains delay time controls. * Triangle facing left is for the start locator, it determines initial delay time * Square moves both start and end locators together * When left locator is first moved you can see the right locator with the same triangle. It shows the end of the selected region, the secondary delay time is determined by the difference between left and right locators * if you drag over the area of the region in a lane, the four-dotted/one circle indicator will change its appearance; this changes the arpeggio mode of the region. If set to leftmost position (one circle) the components go in-sync; if set to maximum value (shown as diagonal line with circles) - components are played sequentially * all settings can be stored as "scene" and multiple scenes can be switched sequentially; there is a set of button to move, add and delete scenes. All scenes will be stored as machine state; it can be exported / imported as a single file or as separate file with current scene in the "setup" view The standalone version always starts with output level set to -70 dB to avoid feedback
