Combine effects work with two pictures: the module’s own image and a second picture read from an AUX bus.
- Morph turns the image into the picture on an AUX bus.
Datamosh can also take its movement from a picture on an AUX bus.
The bus is read as it stands where the module sits in Chain, so the module
that sends to it must sit to its left. Until something has been sent to the
bus, the effect passes its image through unchanged and its panel says so.
