Previously a paid purchase but now available for free for a limited time, Flintpope describes FOUR as a warm analog-sounding synth that uses four different types of oscillator to create rich sounds from warm basses and pads to metallic leads and LOFI soundscapes... all via eighties style synth keyboards.
They say that the synth has just received its final update to V1.5 to include a step sequencer, a pitch sequencer/arpeggiator, a vinyl crackle effect, a noise gen and ten more presets using these new add-ons, bringing the snapshot total to 70.
