All-in-one bass, lead, and drum voice

The BLD-2 packs a complete, premium synthesizer voice into a single module, meticulously optimized for impactful percussion, heavy basslines, and cutting leads.

This comprehensive analog voice couples a highly malleable oscillator and noise source with a multi-mode filter, dual envelopes, and a saturated VCA. While the architecture functions perfectly as a unified, pre-patched synthesizer, the Mk2 revision opens up the signal path, allowing you to use the oscillator, filter, and envelope generators completely independently within your system.

The oscillator core offers continuous blending from triangle through pulse and sawtooth shapes, with specialized pulse-width deformation controls taken from classic Cwejman designs. You can switch the pulse wave between odd or even harmonic biases, while the main gain stage drives from clean tracking into deep saturation before hitting the filter section. The onboard noise generator routes flexibly to the filter or the VCA stage, providing the essential grit needed for acoustic drum modeling or industrial textures.

In use, the filtering and envelope options deliver precise control over transient impacts. The filter switches between low-pass and band-pass shapes with selectable 24dB or 36dB slopes, reacting instantly to the onboard AR and AHR envelopes for tight, punchy dynamic sweeps. Dedicated velocity, accent, and calibrated 1V/Octave tracking inputs turn this module into an expressive live performance centerpiece, anchoring your rack with maximum acoustic weight and authority.
