The enclosure is all-metal with natural cedar wood side panels, hand-assembled in Argentina. The signal path is fully analog: one VCO plus a sub-oscillator per voice, a 4-pole ladder low-pass filter, and a VCA. Control voltages are digitally generated, providing tuning stability without compromising the analog character of the signal chain. Available in blue and black colorways at $1,699 USD.\u003c\/p\u003e\n\n  \u003ch3\u003eAnalog signal path and ladder filter with key tracking and self-oscillation\u003c\/h3\u003e\n  \u003cp\u003eThe VCO per voice runs simultaneous sawtooth and pulse waves with adjustable pulse width modulation. A sub-oscillator one octave below fills the low end without consuming an additional oscillator slot per voice. The 4-pole 24 dB\/oct ladder filter with resonance tracks the keyboard at 1V\/oct — at high resonance and full keyboard tracking, it enters self-oscillation, producing a clipped sine-like tone that blends into the oscillator mix. Filter modulation is handled by EG1 with velocity-sensitive modulation depth, the mod wheel, aftertouch, and the LFO simultaneously. EG2 controls the VCA. The LFO spans 0.1 to 100 Hz with five waveforms — triangle, ramp up, ramp down, square, and sample and hold — routable to VCO pitch, PWM, filter cutoff, and VCA level at the same time. The onboard stereo DSP effects processor (32-bit, 48 kHz, 24-bit converters) delivers an ensemble-type chorus and a stereo delay up to 1 second, with the dry analog signal remaining available at any mix ratio.\u003c\/p\u003e\n\n  \u003ch3\u003eSemi-weighted keybed with aftertouch, sequencer, arpeggiator and MPE\u003c\/h3\u003e\n  \u003cp\u003eThe 3-octave semi-weighted keybed is velocity and aftertouch sensitive. Pitch bend and modulation wheels are designed and manufactured in-house by GS Music. Dedicated sustain and expression pedal inputs cover standard and configurable assignments with adjustable response range. The Keyboard version is the only Bree6 configuration that includes a built-in sequencer and an advanced multi-mode arpeggiator with double and triple operation modes, enabling complex rhythmic patterns without a computer. Full MPE (MIDI Polyphonic Expression) support allows per-note independent control of pitch, pressure, and timbre from a compatible MPE controller. 512 preset slots. Rear panel: power input, USB (data), 5-pin MIDI IN\/OUT\/THRU, balanced stereo L\/R outputs with mono option, and headphone output. Designed and hand-assembled in Argentina by GS Music, founded in 2014 and responsible for the E7, the first fully analog polyphonic synthesizer designed and manufactured in Argentina.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e6-voice polyphony, fully analog signal path per voice\u003c\/li\u003e\n    \u003cli\u003eVCO (sawtooth + pulse with PWM) + sub-oscillator per voice\u003c\/li\u003e\n    \u003cli\u003e4-pole ladder LP filter, 24 dB\/oct, resonance with self-oscillation, 1V\/oct key tracking\u003c\/li\u003e\n    \u003cli\u003e2 x ADSR (EG1: filter, EG2: VCA) with velocity-sensitive modulation depth\u003c\/li\u003e\n    \u003cli\u003eLFO 0.1–100 Hz (triangle, ramp up, ramp down, square, S\u0026amp;H); routing to VCO\/PWM\/VCF\/VCA\u003c\/li\u003e\n    \u003cli\u003eEffects processor: ensemble chorus + stereo delay up to 1 s (32-bit DSP, 48 kHz, 24-bit converters)\u003c\/li\u003e\n    \u003cli\u003e3-octave semi-weighted keybed, velocity and aftertouch\u003c\/li\u003e\n    \u003cli\u003ePitch bend and mod wheels — in-house GS Music design\u003c\/li\u003e\n    \u003cli\u003eSustain and expression pedal inputs (configurable assignment)\u003c\/li\u003e\n    \u003cli\u003eSequencer and advanced arpeggiator (double\/triple modes) — Keyboard version exclusive\u003c\/li\u003e\n    \u003cli\u003eMPE (MIDI Polyphonic Expression): per-note pitch, pressure, timbre\u003c\/li\u003e\n    \u003cli\u003e512 presets\u003c\/li\u003e\n    \u003cli\u003eAll-metal enclosure with natural cedar wood sides, hand-assembled in Argentina\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003ePolyphony: 6 voices\u003c\/li\u003e\n    \u003cli\u003eOscillator: 1 x VCO + sub-oscillator per voice (sawtooth + pulse with PWM)\u003c\/li\u003e\n    \u003cli\u003eFilter: 4-pole ladder LP, 24 dB\/oct, resonance with self-oscillation, key tracking\u003c\/li\u003e\n    \u003cli\u003eEnvelopes: 2 x ADSR (EG1 → VCF, EG2 → VCA)\u003c\/li\u003e\n    \u003cli\u003eLFO: 1 x (triangle\/ramp up\/ramp down\/square\/S\u0026amp;H), 0.1–100 Hz\u003c\/li\u003e\n    \u003cli\u003eEffects: ensemble chorus + stereo delay (up to 1 s); 32-bit DSP, 48 kHz, 24-bit converters\u003c\/li\u003e\n    \u003cli\u003eKeyboard: 3 octaves, semi-weighted, velocity, aftertouch\u003c\/li\u003e\n    \u003cli\u003eControllers: pitch bend + mod wheel (in-house design), octave ±\u003c\/li\u003e\n    \u003cli\u003ePedal inputs: sustain, expression (configurable)\u003c\/li\u003e\n    \u003cli\u003eSequencer + arpeggiator (double\/triple modes) — Keyboard version only\u003c\/li\u003e\n    \u003cli\u003eMPE: yes\u003c\/li\u003e\n    \u003cli\u003ePresets: 512\u003c\/li\u003e\n    \u003cli\u003eMIDI: 5-pin DIN IN\/OUT\/THRU\u003c\/li\u003e\n    \u003cli\u003eUSB: data port\u003c\/li\u003e\n    \u003cli\u003eAudio out: balanced stereo L\/R (with mono option), headphone out\u003c\/li\u003e\n    \u003cli\u003eEnclosure: all-metal + natural cedar sides, hand-assembled\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"GS Music","offers":[{"title":"Default Title","offer_id":53719003136337,"sku":"60096","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/GSMusicBree6Keyboard1.jpg?v=1778222342","url":"https:\/\/wrdtunes.com\/de\/products\/gs-music-bree6-keyboard","provider":"Wired Tunes","version":"1.0","type":"link"}
