Supplier's Notes:
The JHS Pedals 3 SerieThe Bree6 is a polyphonic analog synthesizer that features a fully analog sound generation. It offers six voices of polyphony, each equipped with a single voltage controlled oscillator (VCO), and a sub oscillator. The signal path includes a mixer, a 4-pole low-pass voltage-controlled ladder filter (VCF), and a voltage-controlled amplifier (VCA). The control signals are digitally generated, incorporating one low-frequency oscillator (LFO) and two ADSR-type envelope generators. Additionally, the Bree6 integrates an effects processor with chorus and delay.

The Bree6 interface is engineered for straightforward and intuitive use, featuring one knob per function and ensuring ease of access to its robust features, including MIDI connections, USB, balanced stereo audio outputs, headphone output, and CV inputs.

The signal path in the Bree6 is entirely analog, including a single VCO per voice, a sub oscillator, a mixer, a 4-pole low-pass ladder VCF, and a VCA. The control voltages are digitally generated, comprising one LFO and two ADSR-type envelope generators. It also features a stereo digital effects processor with Delay and Chorus.

The Bree6 features a single VCO plus a sub oscillator per voice. The oscillator includes sawtooth and pulse waveforms, with pulse width modulation control that can be modulated by the LFO. The oscillator tuning can be adjusted, and modulation can be applied from the LFO. The sub oscillator generates a square wave one octave below the main oscillator.

The Bree6's filter is a 4-pole ladder-type low-pass filter with resonance control. It can be modulated by EG1, with velocity affecting the modulation depth, and can also be modulated by the LFO. It can also be controlled by the modulation wheel and aftertouch.

The synthesizer offers a stereo ensemble type chorus effect. It simulates a string or vocal ensemble using multiple delay lines modulated by their dedicated LFOs. The stereo delay can reach a maximum delay time of up to 1 second.

The Bree6 contains one LFO with selectable waveforms (triangle, ramp up, ramp down, square, and random with sample and hold). The LFO's frequency can be set from 0.1Hz to 100Hz, and modulation can be applied to the VCO, VCF, and VCA.

There are two ADSR-type envelope generators in the Bree6, designed for precise control over the dynamics of both the filter and the amplifier.

The synthesizer supports MIDI Polyphonic Expression (MPE), facilitating detailed performance dynamics when used with compatible MPE controllers. The Bree6 has been carefully tested with Osmose, Linnstrument and Geoshred.

Supplier's Notes:
The GS e7 is a subtractive synthesis polyphonic analogue synthesizer. The sound generation is carried out in a total analogue way. Each voice has two voltage controlled oscillators (VCO), a noise source, a mixer, a voltage controlled filter (VCF) and a voltage controlled amplifier (VCA). The control signals are digitally generated by a microcontroller, which is capable of processing three low frequency oscillators (LFO) and two envelopes (EG) of the ADSR type. In addition, it incorporates an effects processor with chorus and delay.

The GS e7 interface was designed to be simple and intuitive.

It also has MIDI connections, USB, balanced stereo audio outputs, headphone output and CV inputs.

Signal path

The signal path is completely analog, featuring two VCO per voice, a white noise source, a mixer, a 4-pole low pass VCF and a VCA. The control voltages are digitally generated, including 3 LFO, 2 ADSR-type envelope generators. Finally, it has a stereo digital effects processor with Delay and Chorus. LFO 1, LFO2 and the delay can be synced with the MIDI clock using a user selectable subdivision.

Oscillators

It features two VCO plus sub oscillator per voice. Each oscillator has 3 different waveforms: triangle, sawtooth and saw-tri (triangle+sawtooth). There is a fine-tuning adjustment and a transpose option, allowing tune adjustment up to +/- 2 octaves. Tuning can also be modulated with any of the three LFOs and EG1

Furthermore, each oscillator has a pulse wave that can be turned on or off, which is mixed with the other waveforms. Its pulse width can be modulated with LFO1 and/or EG1.

Oscillators can be hard synced, with oscillator 1 being the master and oscillator 2 the slave.

The autotuning algorithm takes about 2 seconds to complete. All the voices are tuned in parallel, making a lot faster than usual.

Mixer

The mixer can control the levels and mix the two oscillators, the suboscillators and the white noise or the external input (when the external input is connected, the white noise is disabled).

Filter

The filter is a 4-pole ladder-type low-pass filter with resonance control. It can be modulated with EG1, this modulation an also be affected by velocity. It can also be modulated with any of the 3 LFOs. On the other hand, it features keyboard tracking and it can be controlled by the modulation wheel or aftertouch.

Chorus

There are two types of chorus available: basic and ensemble. The Basic algorithm is subtle and allows you to add some spatiality tothe resulting sound, while the Ensemble algorithm adds a different dimension to the sound, simulating a string or vocal ensemble. The Basic algorithm uses two delay lines, while the Ensemble uses 4 delay lines. Each delay line has its own internal LFO. There are controls for rate, depth and mix.

Delay

The delay can be a stereo delay or a ping pong delay, with its maximum delay time being as long as 1.35s. It is possible to sync the delay to the MIDI clock too. If the delay is synced, the delay time knob controls the time division instead of the delay time. There are controls for the feedback and mix too.

LFOs

There are three LFOs available. LFO 1 and 2 have 5 waveshapes: triangle, ramp up, ramp down, square and random with sample and hold. LFO 3 has the first 4 waveforms and is activated with the modulation wheel and/or aftertouch.
LFO frequencies go from 0.1Hz to 100Hz. Additionally, LFO 1 and 2 have different modes:

Monophonic: The LFO is in phase for all of the voices.

Polyphonic: The LFO is generated to a slightly different frequency for all of the keys pressed. This allows an interaction of the phases, generating more complex modulations.

Keyboard Tracking (KB Tracking): The LFO frequency varies according to the note played following the chromatic scale.

Keyboard Sync (KB Sync): The LFO is restarted when a key is pressed. Each voice has its independent LFO.

Clock Sync: The frequency of the LFO is synced to the MIDI clock signal. The e7 automatically detects the BPM of the clock signal. It can be configured to generate different rhythmic figures.

Keyboard + Clock Sync: The LFO frequency will be a sub-division of the MIDI clock signal. Also, the LFO will be restarted each time a key is pressed.

Envelope generators

There are two ADSR-type envelope generators. There are controls for attack, decay, sustain and release. Attack and release can be modified by velocity and the envelope times have keyboard tracking.

Stereo

By default, the voices have a stereo panning from left to right. By adjusting the stereo spread, it is possible to set all voices to the center or set them from right to left. There is also a stereo motion option that allows this stereo spread to be adjusted by an LFO.

Presets

The synth can store up to 640 presets, 128 of them being multitimbral presets.

Multitimbral

The synth can have up to 4 multitimbral parts. Each part has its complete sound configuration, assignable MIDI channel, keyboard zone, velocity zone, transpose setting and MIDI filter. Additionally, each part can have different voice assignments and/or share some voices.
MIDI Polyphonic expression

MIDI Polyphonic expression is supported by the GS-e7. It was tested using GeoShred, allowing independent pitch control and cutoff for each voice.
