"Hello everyone!

Here's to you my 'No talking demo' of this FREE emulation of the Ensoniq SD-1 developed by Sojus Records, which brings back to life this iconic synthesizers!

This VST3 plugin is a faithful, hardware-level emulation of one of the most unique digital synthesizers of the early ’90s.

Originally released in 1990, the Ensoniq SD-1 comes from a lineage of evolving Transwave wavetable synthesizers, following the ESQ-1, SQ-80, and VFX series. It combines additive-style waveform layering with powerful modulation, placing it alongside classics like the PPG Wave and Waldorf Microwave in the world of hybrid digital synthesis.

This "MAME-based" VST3 plugin brings the SD-1/32 to life inside your DAW for the first time. Despite being a proof-of-concept, it is already fully functional and incredibly deep.

The demo showcases some of the presets created directly from the engine – from lush pads and evolving textures to digital timbres and analog-style patches. Each patch can layer up to 6 waveforms from the original ROM, shaped by dual multi-mode filters, complex envelopes, LFOs, and an extensive modulation matrix. The built-in effects processor adds classic reverb, chorus, flanging, and delay.

Key features of the plugin include:
• Full VST3 support (Windows & macOS, Intel + ARM)
• Complete MIDI implementation including polyphonic aftertouch
• Full VST automation (all controls)
• Import of original VFX / VFX-SD / SD-1 SysEx files
• Resizable GUI with multiple panel layouts
• Support for original disk images and cartridges
• Optional multi-output routing (main + aux)
• Built-in sequencer support (with original OS disk)
• And much more...

⚠️ Important: This plugin requires original Ensoniq SD-1 ROM files (not included for copyright reasons). Please check the documentation for setup instructions.

⚠️ Note: Due to the nature of the emulation, CPU usage can be high and only one instance can run per DAW session.
