x0x is a hardware and firmware effort to provide some of the capabilities of
the early Roland gear (e.g. 202, 303, 606, 707, 808, 909) in a modern form
through the use of microcontrollers and digital signal processing.
It is a collaborative effort between Steve Richardson (hardware & drivers) and
Noah Vawter (firmware & DSP).
Two prototypes have been built around an
DSP evaluation board, an Axiom
Manufacturing CMD-11 68HC11 single board computer, and a custom user
interface PC board containing buttons, knobs, and interface circuitry. Both
prototypes have been used in concert and recording situations with good
The driving philosophy behind the x0x project is to provide efficient and
powerful editing capabilities while the sequencer is running.
The x0x sequencer is a hybrid between a MOD-style editor, a pattern-based
vintage drum machine such as the 606, and a vintage seq/synth like the 202.
This combination makes it perfect for live electronic music.
