This Bass Bot is fully functional and in great condition. It requires either 4 C batteries or a 9V DC center negative power supply (Not included).
The Bass Bot is an analog, monophonic synthesizer and sequencer, an incredible reproduction of one of the most sought-after analog synths ever, the The Roland TB-303. The sound is authentic not because of good sampling or modeling, but because it uses identical circuitry - classic transistor-based circuit design, using 21st century technology.
The sequencer uses classic step-entry programming, and stores up to 224 editable patterns, as well as 224 bot-generated preset (non-editable) patterns. The Bass Bot holds 7 songs of up to 127 bars, with everything stored in onboard flash memory - which means it will stay there when you turn the unit off.
It also includes an arpeggiator function and MIDI (as opposed to the DIN Sync in the original 303).
