Twin Bass is a bass synthesizer designed to deliver rich mid-range bass textures alongside a powerful sub bass foundation. It features a unique double filter architecture, allowing for flexible sound shaping with two filters that can operate in parallel or series. This setup enables the creation of deep sub basses with one filter while crafting intricate mid-range stereo textures with the other. The synth also excels at producing vocal-like timbres, expanding its sonic palette beyond traditional bass sounds.

Equipped with two oscillators offering classic waveforms including sine, saw, ramp, triangle, pulse, and noise, Twin Bass provides a wide range of tonal possibilities. The second oscillator can also process external audio signals, adding further sound design options. Its filters include multiple low pass, high pass, and bandpass types, with the second filter featuring stereo capabilities and independent cut-off controls for each channel. A feedback loop and a distortion effect with both hard metallic and soft tube-like modes enhance the tonal complexity, and the distortion can be applied selectively before or after filtering.

Twin Bass incorporates extensive modulation options with three LFOs synchronized to the host, three ADSR envelopes, and a modulation matrix with five slots connecting numerous sources to destinations. It supports monophonic and polyphonic modes with glide, and offers individual outputs for each filter, making it easier to process sub and mid-range signals separately in a mix. Additional features include MIDI learn functionality for quick automation, a visual structure display to track signal flow, and helpful pop-up hints for intuitive control navigation, making Twin Bass a powerful tool for crafting dynamic bass sounds.
