Unleash the Beast – Bit Beast Synth Demo

February 11, 2013 · Posted in Uncategorized 

A demo song of the Bit Beast synthesizer. All sounds (including drums) are made with the Bit Beast and recorded into Ableton Live. Some minor FX were added to some tracks (reverb, delay, EQ).

The Bit Beast utilizes a method of tone generation commonly called ‘bit banging’. It turns a digital bit on and off at the frequency of specific notes. This method of creating sounds is typical of old videogame and computer systems. The processor that reads the MIDI signal and ‘bit bangs’ the notes is the same one used by the Arduino UNO (ATMEGA328P-PU). All the code is written and compiled in the Arduino software. This means that anyone with an Arduino UNO can edit and tweak the code. This will allow musicians to customize their synth to some degree, and expand upon the base functionality.

The notes are then chopped up and processed using CMOS logic chips. The effects created are common in the DIY realm, but seldom available in commercially available synthesizers.

The sound then passes through two analog voltage controlled filters. Both filters are unique designs that offer very different sounds. Filter 1 is a 12db state variable filter with low-pass and band-pass modes and overdrive control. Filter 2 is a 6db filter with low-pass and high-pass modes and a squelchy distorted resonance. The filters can be configured in parallel or two different serial configurations. Both filters have their own LFO and envelope generator.

The final step that the sound passes through is an analog VCA with a dedicated envelope generator.
