The software at the heart of the M700 became its legend. It was not merely firmware; it was a narrative engine. Developers built layered abstractions: low-level DSP kernels that handled sample-accurate timing and alias-free oscillation, and higher-level modules that stitched those kernels into expressive instruments. The architecture felt like a city of rooms—some raw and industrial, others domed with warm reverb—each room a node in a living patch bay.
