Robert Syrett has posted an updated version of the O-Toast, his Audulus clone of the Make Noise O-Coast. An attempt to make a version both more CPU efficient and closer in sound to O-Coast, as well as reflect his growth in understanding how to design things like looping function generators.
Along with the new 1-Toast, he’s also included µModular versions of the basic O-Coast building blocks, something that I think makes a lot of sense in the Audulus context. As he points out, there are also certain bits (such as the attenuverter) that are better out of the box – elements that benefit from being copied and used in multiple places.
Treating the component parts as separate modules is also a direction that Make Noise have taken with expansions on O-Coast core elements in their Contour and Dynamix modules.
