Crumar Sorrento is a dual-manual physical modeling spinet organ, manufactured in Italy by Crumar Instruments. Each unit ships with the BURN rotary speaker simulator pedal connected via a single ONE-CORD cable that carries both audio signal and power simultaneously.
Three sound engines and an independent bass output
The Sorrento is not another B3 sample player — it houses three distinct physical modeling engines in one instrument. The first is a full console tonewheel engine based on VB3 algorithms; the second is a vintage spinet with the specific tonal character of rock and progressive organ from the 1970s (Genesis, Pink Floyd); the third is a transistor organ with its own edge and grit, unavailable in tonewheel emulations. Each of the two 49-key manuals has octave shift functionality, giving the effective range of a full console organ without the physical footprint of a console. Nine real mechanical drawbars — not encoders — and two drawbar presets per manual with a quick storage mode. The bass section is a separate monophonic physical modeling synthesizer with independent Volume, Tone, and Decay controls, routed to its own dedicated 1/4" output. Bass to Lower mode routes bass playing to the lower manual. An onboard fully analog distortion circuit (Level, Drive, Tone) and ring modulator add a further layer of expression without any external processor.Modularity, ONE-CORD and integration with BURN
The Sorrento intentionally omits built-in reverb and rotary simulation — those functions are handled by the included BURN pedal, connected via the ONE-CORD RJ45 port. The modular approach means BURN can be replaced by any other rotary effect, a real Leslie cabinet, or a guitar amplifier. Three independent mono outputs — ONE-CORD (audio and power to BURN), main organ output, and bass output — allow full independent signal routing for each source. MIDI IN/OUT (5-pin DIN) and USB Type B for computer connectivity. Expression and sustain pedal inputs. An OLED display with built-in editor and navigation handles all parameter editing directly on the instrument. Boot time is instant — no operating system startup delay.KEY FEATURES
