Audio Examples

The Avalon from Abstrakt Instruments is a high quality analogue bassline synthesiser and sequencer.

The core circuitry of the Avalon is based on the revered Roland TB-303 bassline synthesiser, to which a new layer of analogue and digital circuitry has been added to position the avalon as the premier bassline synthesiser.

Core analogue and digital circuitry based on TB-303

Incorporates layout and parts from the original bassline, including carbon film resistors, United Chemi-con electrolytic capacitors, poly foil film capacitors, original IC's, and Sanyo/on semi & Mitsubishi transistors.

Synth Cartridge System

Compatible with the cartridge system in the form of filter plugin cards.

Extensive Analogue Control

In addition to the six analogue controls of the original bassline, the avalon includes controls for sub osc/ext input level, filter tracking, accent decay time, VCA decay (normal to full off), utility envelope attack & decay time, utility envelope to VFC and VCA modulation depths, frequency response select (normal and full range).

Extensive Digital Control

In addition to backwards compatibility with the TB-303 pattern write pitch & time modes the avalon incorporates new progamming modes making extensive use of (16) step LED switches. Patterns can be up to 64 steps in length (up to 4 sections x 16 steps) and each pattern can have numerous scales including triplet modes. Real-time editing includes slide time select, utility envelope trigger mode, pattern step skipping, pattern reverse, rotate, random, & shuffle. There is also an arpeggiator that can be performed real-time or recorded directly into a pattern.


Sync source can be selected as internal, MIDI, or DIN Sync, and the Avalon sends both MIDI & DIN Sync.

Audio Inputs & Outputs

Includes main & headphone outputs, saw and square outputs (+/-5V), external input, and filter and VCA outputs.

CV Inputs & Outputs
