Manatee User Manual - V1.0
Introduction
A note from Fred

Thank you for choosing Manatee!

You have just adopted the most advanced and flexible digital synthesizer from Fred's Lab!

Drawing inspiration from classics of the early 2000s, Manatee combines nostalgic elements with modern twists. Beyond its ability to recreate iconic Pop / Dance / Trance / Electro / Ambient sounds, Manatee stands out with its extensive modulation options, full MPE support and built-in effects.

This project embodies three years of dedicated hardwork with much research and development, resulting in a completely fresh design with unique DSP algorithms, crafted from the ground up. Combining my best efforts and knowledge, Manatee is intended to be intuitive to operate, fast to brew original sounds with while offering very rich synthesis capabilities.

After trying out the factory presets, I encourage you to take time to explore the instrument. I hope it surprises you and sparks new ideas for your music!

Love from Bonn / Germany!
Fred

A note from Till & Bert

The Manatee desktop synthesizer was conceived, designed and programmed by Frédéric Meslin, Fred for short, with great attention to detail and the courage to innovate. Fred himself is a keyboardist in a jazz band and has many years of experience in programming and developing synthesizers in his own company. Before that, he worked for two well-known European synthesizer manufacturers after completing his studies.

Manatee User Manual - V1.0
Introduction
Preface
Manatee is a purely polyphonic & multitibral digital synthesizer offering 10 to 16 voices - depending on sounds complexity - which are shared among four parts. Latest MPE - MIDI Polyphonic Expression - standard and regular polyphonic aftertouch are also supported.

But what exactly is a "Manatee"?

Manatee is the English name for one of the nicest marine mammals. With a round tail and being mostly herbivorous, it's sometimes referred to as a "sea cow". These water-dwelling animals can be found in the Caribbean and on the Atlantic coast of Brazil and Venezuela, the Amazon and in waters of West Africa. Their population is classified as endangered on the IUCN list.

Risk of Hearing Damage

The Manatee, like any musical instrument used with headphones, earbuds, speakers, or PA systems, can produce high sound levels across a wide frequency range. Your hearing is extremely sensitive and can be permanently and irreversibly damaged by excessive volume.

Please always protect your ears, and those of your audience, by keeping volume at safe levels.

Manual Notations

To ease the reading and understanding of explaination found in this user manual, a few conventions were used:

• CAPITAL LETTERS denotes a sound engine or system parameter.
• <KNOB> denotes a physical knob.
• [BUTTON] denotes an illuminated switch or a button.
• -LED- denotes an LED - Light Emitting Diode.
• "DISPLAY" denotes a text or representation on the display.

Editing Philosophy

The Manatee user interface was designed with two objectives in mind:

• Allowing quick creation of effective sounds.
• Simplifying live edits with one hand.

To achieve this, the layout does not closely follow traditional synthesizer conventions. Instead, the controls are arranged to make the operation fast and easy. Some modules are intertwined, and some sections may not be where your muscle memory expects them, at first. Please do not worry, after a couple of hours practicing it will feel simple and logical. This manual is here to guide you through that learning curve.

Some things to keep in mind: there are specific sections with dedicated knobs, LEDs and buttons and there is the central section with the LCD display and the 3 macro knobs located below it. While physical controls from the specific sections always edit the same parameter from the selected part, the <MACRO> knobs always edit the parameters being displayed on the screen. Up to 3 parameters can be displayed at a time, depending on the selected editing page.

Manatee User Manual - V1.0
Basics
Front Panel

Let us have a first look at the synthesizer front panel:



The front panel of Manatee is organized into five main sections: Envelopes, Sources, Macro Knobs, Filters, and Mixing + Effects. LFOs and advanced modulations share the the Macro Knobs section controls. At the top of the instrument, are found all the connectivity options, while the central section allows you to select the currently edited part and access deeper setting menus via the ALT button.

All knobs on the Manatee are potentiometers, not encoders. This choice was made to offer precise control and an analog-style tactile feel. However, this also means that the physical position of a knob does not always reflect the current value of a parameter, especially after loading a preset or switching between multi's parts. This is also particularly noticeable in the Macro Knobs section, where parameters change depending on the currently selected page.

No need for great concern: each potentiometer can operate in one of three modes, JUMP, OFFSET, or CATCH, allowing you to tailor the response to your editing style. These modes will be explained in detail later.

Pay close attention to the navigation arrows located just below the Macro Knobs. These arrows are used to navigate between parameter pages or to select the current Preset or Multi, depending on the context.

Manatee User Manual - V1.0
Basics
Front Panel

The layout flows from top left to top right, like the shape of a smile. It begins with the contour of the sound (Envelopes), moves through timbre and movement (Sources and Macro Knobs), continues into the body of the sound (Filters), and finally reaches the ambiance stage (Mixing & Effects).

One distinctive characteristic of the Manatee is its shared envelope design. While there are two separate envelopes, one for the filter and one for the amplifier, some of their time parameters (ATTACK, SUSTAIN, and RELEASE) are initially linked. This shared control makes it quick and intuitive to shape the overall contour of a sound with just a few adjustments. When more detailed shaping is needed, the envelopes stages can be individually enabled or disabled, allowing more independence of the envelopes.

With the exception of the three LFOs and the Modulation Matrix, each synthesis block has its own section. The edition of these modules is performed exclusively through the <MACRO> Knobs. Dedicated buttons labeled [LFO•1], [LFO•2], and [LFO•F] are provided, allowing you to quickly jump to the corresponding editing pages without having to scroll manually.

Manatee User Manual - V1.0
Basics
Signal flow

Let's look at the signal flow. Aside from its unique Spectral Generator, multitimbrality, and MPE support, the Manatee’s architecture is quite conventional. It features two oscillators, two envelopes, three LFOs, and two filters with a distortion unit. What truly sets it apart are the innovative functionalities coming within each module, the powerful and flexible modulation system, and the high-quality built-in effects and mixing tools (EQs and Mix reverb).

When exploring the internal modules of the Manatee, it's important to distinguish between Voice, Part, and Multi level modules. Most modules operate per voice, meaning each of the 16 voices has its own independent instance. However, some modules are shared across voices within a part. These include LFO•1, LFO•2, the dual equalizer, delay, spectrum maker, and arpeggiator, all of which are per Part, producing a common output for all voices assigned to that part. Finally, the reverb module is at the Multi level, it is global, with only one instance shared across the entire instrument.

The Manatee is powered by two dual core DSPs, with the processing load being dynamically distributed between them. The resource allocator continuously optimizes performance to deliver the best possible results. To maximize polyphony, you are encouraged to disable unused modules, this frees up DSP cycles. As a rule of thumb, the simpler a preset is, the more voices it can support simultaneously.

Manatee User Manual - V1.0
Interface
Display

At the home page of a Multi or a Part, the screen top left indicates "MUL" or "P1" to "P4" respectively. One reaches the home page by pressing part buttons [1] to [4] or the [MULTI] button.

By default, if the synth is left untouched for 30 seconds, the display will automatically return to the currently edited part home page. This return behavior can be disabled in the system menu.

At a part home page, the configured MIDI channel is displayed after the "C:". The number of voices currently active is displayed after "V:". The percentage on the far right of the top line indicates the processors load. When using effects, this value can be greater than zero even if no notes are played.

The bottom line of the display shows the memory location of the multi (M1 to M16) or bank (A-D or I with the numbers 1 to 64) for parts, as well as the eight-character alphanumeric name assigned to the part and the category name with three letters.

If a Multi has been changed compared to the saved values, i.e. has been edited, an inverted "E" (for Edited) is shown at the top right of the display after "MUL" or the number of the part. An inverted I (for Imported) indicates that a Multi or a Part has been freshly received via SysEx and can now be tried out, but has not yet been saved. Without saving, multis or parts loaded via SysEx are replaced after the program change. This prevents accidental overwriting of data stored in the Manatee by multis and parts received via SysEx.

Interface
Macro Knobs

There are three <MACRO> knobs below the display. These are used to edit the parameters seen on the display, e.g. to select the memory bank and the memory number. Sometimes less than three <MACRO> knobs are used. Which <MACRO> knob does what is determined by the arrangement of the parameters on the display.

If you maintain pressed or lock the [ALT] switch while using a <MACRO> control, the value is changed in coarse steps. This eases the setting of bipolar parameters to exactly zero or some specific values.

Arrow buttons

You can navigate within the menus using the [ARROW] buttons to the right and left of the middle <MACRO> knob. The [ARROW] buttons can not only be used to scroll within menu pages, allowing access to the "advanced" parameters but also to click through from one section to another, as all menus are chained together, figuratively speaking. And once the last page of the last section is reached, another press of the [ARROW] in the current direction will jump back to the beginning, performing a full loop in the pages order.

There are some functions that can ONLY be accessed using the [ARROW] buttons.

ALT switch

The [ALT] switch grants access to advanced options and hidden features! You can lock the ALT mode by performing a double-click (two quick presses in a row) and unlock it with a single press. When ALT is active, the [MULTI] and part [P1] to [P4] switches become shortcuts to key menu pages like SETUP, MIDI, REVERBERATION, and ARPEGGIO. Additionally, pressing the [LFOx] switches while holding ALT gives quick access to the Modulation Matrix slots.

ALT is also used in combination with any knob to enable coarse parameter editing. A full list of ALT combinations and their functions can be found later in this manual.

MIDI LED

The -MIDI- LED above the left <MACRO> knob is context-dependent.
If a part switch, [P1] to [P4] below the display is active (lit red), MIDI note events received on the selected part MIDI channel will blink the -MIDI- LED. However, the LED does not take into account the selected note range of a part. All other MIDI messages on the channel is ignored. Aftertouch, controller change or MIDI clock messages are not displayed. If the [MULTI] switch below the display is active, all MIDI note events triggering one the four parts will blink the -MIDI- LED.

Key Combinations

Here is a exhaustive list of the button combinations one can perform:

• [ALT] + [P4] switch: scans all knobs at once and transfers their values to their respective parameters for the currently edited part. This is often called "manual" or "panel" mode. It synchronizes all potentiometers state with their corresponding Preset parameters value.

• [ALT] + [SAVE] button: opens the Utility menu. Right now, only the clock monitor is available. From left to right, this first shows the internally set tempo in BPM (beats per minute), then the tempo received via MIDI clock (rounded to compensate for fluctuations) and the tempo measured at the analog clock input. The internal tempo is configured in the SETUP menu on page 2 with the other clock settings. The prefered clock source and the PPQ (pulse per quarter) are also selected there.

• Hold [DRIVE] button: MIDI panic! All voices played by the Manatee are stopped. All MIDI controllers are also reset and the working memory of the delay is blanked. This function comes in handy when notes are stuck due to corrupted MIDI transmission or when you want to release on-going drones.

• Hold part [P1] to [P4] switch: sends a data dump of the part edit buffer via MIDI SysEx. Please refer to "Sending and receiving SysExes" part of this manual.

• Hold [MULTI] switch: sends a data dump the multi edit buffer via MIDI SysEx, consisting of the Multi data and the content of the four Parts contained therein, as a total of five SysEx dumps.

• [ALT] + [GEN] button: opens the secret Spectrum Editor.

• Hold [ALT] + Power switch: forces the Manatee to stay in bootloader. The display then shows "...AWAITING SYX...". A new firmware version can then be loaded via SysEx. To abort this procedure, just restart the instrument again without holding any switch or button.

Connection
Power input

At the back of the Manatee, on the left side, you'll find the main power switch used to turn the unit on and off. The Manatee comes with a universal power supply unit, compatible with 100–240 V and 50/60 Hz AC mains. It outputs a regulated 12 V DC through a 2.1 mm barrel connector (center positive), and includes a set of interchangeable mains plugs for international use.

The power supply provides up to 420 mA, while the Manatee typically consumes around 350 mA. To save energy, it is recommended to either unplug the power adapter from the socket or use a switchable power strip to turn it off when the instrument is not in use.

Audio outputs

The Manatee features both a Main and an Auxiliary audio output, each configured as stereo pairs using standard 6.35mm jack sockets. These outputs can also be reconfigured as four separate individual outputs, or one stereo output and two individual outputs, providing flexible routing options.

The Auxiliary output employs a TRS (Tip-Ring-Sleeve) socket. This allows an external audio signal to be fed into the Manatee through the ring contact of any of the Auxiliary output jacks. The input signal is then mixed directly to the Main output without processing, enabling you to connect an external instrument without the need for a mixer or inserting external audio effects on the Auxiliary bus by using the appropriate cables.

With an insert or Y-cable, you can use the Auxiliary outputs and inputs simultaneously. Typically, the two separate ends of such cables follow this convention:

• Black (tip) = output
• Red (ring) = input

Alternatively, the Auxiliary output can be used as a regular simple output, but in this case, an unbalanced TS (Tip-Sleeve) jack cable MUST be used to avoid signal issues.

Finally, the Manatee includes a stereo headphones output over a 3.5 mm socket for private monitoring.

MIDI DIN Sockets

At the back of the Manatee, next to the power input, you will find the familiar trio of DIN sockets for MIDI IN, THRU, and OUT. These ports are fully compliant with the standard +5V MIDI specification. Nothing fancy, just the reliable, standard MIDI connectivity one can always count on!
