FPGA-based algorithmic oscillator core sampled at 50MHz

Waveshapes: sine, sawtooth, square, triangle, noise, pulse

Can be hard-synced to DDS 1

LFO mode

Sub oscillator mode (can be activated when in LFO mode)

Pulse waveform with variable pulse width and PWM

LFO and envelope modulation of DDS 1 & DDS 2 pitch

Selectable ½ Super or full Super mode for DDS 1

Sister oscillator detune spread control for Super waves

Pulse-width control for pulse waveform

LFO and/or ENV 1 can modulate the sister oscillator detune spread for the Super waves and the pulse-width for the standard waves

DDS 2 to DDS 1 cross-modulation for deep FM Sounds

Stereo audio input that feeds through the VCA, VCF and effects section

Gate triggering of envelopes and LFO 1 based on audio input level with a variable-gain input stage

Main LFO with low and high-frequency modes, rate adjustable from 0.05 Hz to 20 kHz

Left-right phase control for stereo effects, harnessing the binaural sound engine

Can be free-running or reset on note press

One-shot mode allows LFO 1 to act as an additional envelope

Keyboard tracking mode for high-frequency LFO (useful for FM sounds)

LFO 1 can be mapped through the DDS 1 or DDS 2 audio path in either fixed or tracking high-frequency modes for use as a drone or a third oscillator

Can be synchronized with the sequencer and arpeggiator as well as an external clock

Adjusts the mix-level of DDS 1 and DDS 2 audio signals

When in X-Fade mode, adjusts split point on the keyboard of crossfaded DDS 1 and DDS 2 (or audio input) signals

The SSI2144 reprises the SSM2044 of legacy chipmaker Solid State Micro Technology, which many believe to be the best-sounding analog synthesis filter IC ever produced. Based on Dave Rossum’s patented classic improved ladder topology, the SSI2144 allows rich tonal characteristics that showcase the very best attributes of subtractive synthesis.
