More details


550,00 € tax incl.

x0xb0x is monophonic, with VCO (Voltage Controlled Oscillator) capable of 4 octave. Adjustable effects like tune, cut-off frequency, resonance, envelope modulation, decay and accent. All filter controls on analog knobs. Intuitive sequencer with piano keyboard for inputting notes, rests, slides, accents, octave-change.

This projec is open source, developed by LadyAda in cooperation with German patner, who reverse-engineered the original TB303 to faithful reproduce the analog circuitry. X0xb0x uses the exact parts (amps, transistors) found on the original TB303, with same circuit topology. Sequencer is instead totally new and intuitive, based on modern mcu (micro controller units), to easy and extend the note input possibilities.

Main features:

  • Syntesizer with analog (microncontroller unit controlled) VCO (voltage controlled oscillator).
  • Monophonic, 4 octave, can output square wave or saw wave.
  • Adjustable (via analog knobs) filters: tune, cut-off frequency, resonance, envelocpe modulation, decay, accent.
  • Microcontroller unit based sequencer. Note input on piano keyboard. Easy notes input (easier than on original TB-303). Edit single pattern, combine multiple patterns into a track. 16 memory banks for patterns, 16 memory banks for tracks.
  • Intuitive record & playback of pattern and sogns, with on-the-fly modification of pitch shift, octave change, note-to-rest, accent and slide.
  • Syncing with external devices via MIDI or Roland DIN (DINSYNC).
  • Standard MIDI IN/OUT/THRU + DINSYNC. Can play MIDI notes arriving on MIDI input.
  • Gate and CV ports, Mix Out, Mix In and Phones audio connections.
  • EEProm memory. Will retain pattern and songs without external supply or internal batteries.
  • USB connection for computer interface and control.
  • Firmware upgradable.
