Manufacturer's description
With great dedication and commitment, it is an honor for us at GS Music to present the Bree6 Keyboard version, our first synthesizer with an integrated keyboard, designed and produced in Argentina for the world. This instrument represents a significant milestone in our journey as instrument makers and reflects our vision to create tools for musicians who value quality as a non-negotiable standard.
The Bree6 Keyboard is built to deliver an intuitive and expressive analog experience, combining a robust architecture with a carefully crafted user interface that invites exploration and creativity.
Built upon a six-voice analog architecture, the Bree6 Keyboard delivers a powerful and expressive sound engine, capable of producing a wide range of textures, from solid basses and articulate leads to rich, evolving pads. Its carefully designed signal path, combined with an intuitive interface and a high-quality keyboard with velocity and aftertouch sensitivity, provides a direct and immersive playing experience.
Expanding beyond the desktop version, the Bree6 Keyboard incorporates an advanced arpeggiator and a built-in sequencer, significantly enhancing its creative capabilities. The arpeggiator features multiple layers of operation, allowing for complex rhythmic patterns and evolving sequences, while the sequencer enables users to capture and develop musical ideas directly from the instrument, making the Bree6 Keyboard a complete performance and composition tool.
Every aspect of the instrument has been developed with careful attention to detail, combining a refined aesthetic with a robust and purposeful construction. The Bree6 Keyboard features an all-metal build complemented by natural cedar
wood side panels, and is hand-assembled to ensure quality and consistency in every unit.
It incorporates a semi-weighted keybed with velocity and aftertouch sensitivity, along with pitch bend and modulation wheels engineered in-house to provide precise, reliable, and expressive control.
Immediate control. No menu-diving.
The Bree6 Keyboard version is designed to deliver an immediate and intuitive hands-on experience, eliminating the need for deep menu navigation. Its interface follows a one-knob-per-function philosophy, providing direct access to all key parameters for fast and precise sound shaping.
Expressive control is at the core of the instrument. Velocity can be assigned to modulate both the filter and amplifier response, allowing dynamic tonal variation based on playing intensity. The modulation wheel provides real-time control over LFO modulation depth, targeting the oscillator pitch and/or the filter cutoff for expressive performance.
The instrument features a semi-weighted keybed with velocity and aftertouch sensitivity, ensuring a responsive and musical playing experience. It also includes dedicated inputs for sustain and expression pedals, with the expression pedal
offering configurable assignment and adjustable response range for flexible control.
In addition to its performance capabilities, the Bree6 Keyboard integrates essential connectivity options, including MIDI, USB, balanced stereo outputs, headphone output, and external control inputs, making it equally suited for both
studio production and live environments.
Signal path
The Bree6 Keyboard version features a refined signal path engineered to preserve the character and integrity of its analog sound while incorporating modern control flexibility.
The audio path is fully analog, beginning with a Voltage-Controlled Oscillator (VCO), followed by a sub oscillator and mixer stage, then passing through a 4-pole low-pass ladder Voltage-Controlled Filter (VCF), and finally into a Voltage-Controlled Amplifier (VCA).
Control signals are digitally generated and include one Low-Frequency Oscillator (LFO) and two ADSR envelope generators.
A stereo digital effects section is integrated into the architecture, combining delay and chorus, maintaining a fully analog dry signal while blending in high-quality digital processing for added depth and movement.
Oscillator
The Bree6 Keyboard version features a single analog VCO per voice, complemented by a dedicated sub oscillator to enhance low-frequency content. The oscillator provides two primary waveforms: sawtooth and pulse. The pulse waveform supports Pulse Width Modulation (PWM), which can be dynamically adjusted and modulated via the LFO to create evolving textures.
Pitch can be finely adjusted, and modulation sources can be applied to introduce vibrato and other expressive variations. The sub oscillator generates a square wave one octave below the main oscillator, adding weight, depth, and richness to the overall sound.
Filter
The Bree6 Keyboard version is equipped with a 4-pole ladder-type low-pass filter, designed to deliver smooth and musical frequency shaping. The filter includes resonance control and supports multiple modulation sources, including Envelope Generator 1 (EG1) with velocity sensitivity, LFO modulation, and performance controls such as modulation wheel and aftertouch.
This flexible modulation system enables a wide range of tonal possibilities, from subtle shaping to more aggressive and resonant filtering.
Chorus and delay
The Bree6 Keyboard version includes a built-in stereo effects engine designed to enhance spatial depth while preserving the analog core of the sound. The chorus effect creates a rich ensemble character by simulating multiple detuned voices through modulated delay lines, resulting in a wide and immersive stereo image.
The stereo delay offers adjustable timing and feedback, with a maximum delay time of up to 1 second, allowing for anything from tight rhythmic echoes to expansive ambient textures.
LFO
The Bree6 Keyboard version includes a versatile Low-Frequency Oscillator that acts as a central modulation source. Selectable waveforms include triangle, ramp up, ramp down, square, and random (sample & hold). The LFO frequency ranges from 0.1 Hz to 100 Hz, enabling both slow evolving modulations and fast modulation effects. It can be routed to multiple destinations, including oscillator pitch and PWM, filter cutoff, and amplifier level.
Envelope generatora
The Bree6 Keyboard version features two ADSR envelope generators, providing precise control over both tonal and amplitude dynamics. EG1 is assigned to filter modulation, while EG2 controls the amplifier. Each envelope includes attack, decay, sustain, and release stages, allowing detailed shaping of the sound over time.
MIDI Polyphonic Expression (MPE)
The Bree6 Keyboard version supports MIDI Polyphonic Expression (MPE), enabling advanced per-note control when used with compatible controllers. This allows independent manipulation of parameters such as pitch, pressure, and timbre for each note, significantly expanding expressive capabilities and performance depth.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK, 'next working day' shipping is free if the order value is over £150, and £5 otherwise. We can also ship on a 'next working day before 12pm' service, which costs £6 for orders over £150 and £7.50 for orders under £150.
Shipping to mainland EU typically costs between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of DPD, Royal Mail and Parcelforce for the UK, and for international orders it's either DHL, FedEx, UPS, Royal Mail or Parcelforce depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we aim to dispatch the same working day if we get the order before 16:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes the couriers may come to collect a little earlier than scheduled which would also push an order into the next day.
Saturday/Sunday shipping
If you're in the UK and you order before 16:00 on a Friday then we can send something for a Saturday or Sunday delivery with DPD. This is FREE for order values over £350, £5 for order values between £75 and £250, and £7 for order values under £75. (NB: this applies to UK mainland addresses only). Please note that any orders placed after 16:00 on a Friday will ship on the Monday.
International shipping times
Since April 2020, the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer. There is absolutely nothing we can do about this, unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
