User manual

## Introduction Thank you for choosing SL MK2, a new chapter in keyboard controllers. Housed in a stylish and robust cabinet, it is based on a completely new technology and innovative UX Logic user interface derived from Numa X Piano. The keyboard features Aftertouch control and, together with the programmable Sticks and transport controls, provides total control over the musical performance. Seamless integration with Numa Player, a built-in pro audio interface and high-definition MIDI 2.0 protocol make this controller unique. ![Schema setup](example.svg) The example above shows how SL MK2 can be used in a typical studio setup. The connections: - **USB-C port** connected to a computer running a DAW or a standalone software. - **MIDI In/Out** connected to external devices. - **L/R** audio outputs connected to active stereo speakers. - **Phone output** connected to headphones. - **Pedals 1, 2, 3** connected to switch, switch or expression, and multi-function pedals. In this setup, the USB connection allows MIDI recording to the computer and audio playback of the virtual instrument to the speakers. ## Power and connection 1. Connect the USB-C port to a power source using the supplied power adapter. 2. Switch on the SL using the power button next to the power plug. ![Rear connections](connections.webp) ### USB Power The instrument can also be powered by a connected device, using the supplied cable or a shielded quality certified USB cable. Make sure the computer or the mobile device can provide enough power. When possible, avoid using USB hub and adapters. ### USB data The USB connection can be used for: - MIDI In/Out - Audio In/Out - Numa Player integration - App data through SL LINK protocol - DAW control To transfer data via USB, connect the SL to your device using a USB-C cable ([read more about USB connection](/support/articles/1876513/)). ### Pedals Connect the pedals to the corrsponding sockets, labelled as *PED1*, *PED2* and *PED3*: - **PED1**: You can connect a switch pedal. - **PED2**: You can connect either a single switch pedal or a volume/expression pedal. - **PED3**: You can connect a switch, volume/expression or a [Studiologic SLP3-D](/products/slp3-d/), as explained in the related chapter. [Read more about pedal compatibility.](/support/articles/1970321/) ### Audio Output If you wish to use external amplification systems, or record the instrument sounds, connect the Left and Right audio outputs to the inputs of your mixer or amplifier, or to the inputs of your computer audio board, using suitable cables. Please note that SL is a controller keyboard, so it doesn't have any internal sounds.
However, thanks to the Audio over USB feature, you can route audio data from your computer or other compatible digital device to analog audio output.
### Headphones The Headphones output can be used with an headphones set or as an additional stereo audio output. ## Panel - display and navigation ![Top panel](panel.webp) ### `A` Knob Rotate the A knob to adjust or quickly disable the analog audio output of your SL. ### `B` Knob The B knob is similar to a *Master MIDI Volume*. If you are using more than one Zone, you use this knob to control the volume of all active Zones. ![A/B knobs](audio_knobs.webp) ### Zone controls **Encoders** - Rotate the zone knobs to adjust the volume of the corresponding zone. - Press a knob to mute the corresponding zone. **Buttons** - Press the buttons to select the corresponding zone. - Long press the button to enter in Zoom mode and adjust the associated parameters. - In DAW mode, you can control your DAW: *Select Buttons* become *Transport Buttons*. ![Zone panel section](zones.webp) ### System navigation ![System navigation](navigation.webp) ## Programs SL MK2 is organized in Programs. A Program is based on 4 Zones. Each Program stores all Zone parameters and settings. A Zone can have 3 different status: - ON (colored) - OFF (black) - MUTE (gray) The Home screen displays the current Port, Channel and Volume of each Zone. Press the **Home** button to change the current view to ***Zoom mode***. The Zoom mode shows a more detailed view of the current Zone. ![Home screen to Zoom](home-switch.png) ### Program selection There are two ways to select Programs with the Main Encoder: - **Rotate** to change in sequence. - Press **up/down** to show the list and jump to the desired Program. ![Program selection](display_PROGRAMS.png) In the same way, you can select the Programs assigned to a Favorite (see next paragraph). ## Favorites A Favorite is a collection of Programs in a desired order, like a set list. The purpose of Favorites is to provide a quick way to get the right sound during a live performance. You can store up to 24 Programs in each of the 8 Favorites. ![Program selection](display_FAVORITES.png) ### Save the changes 1. Press **Apply** to display the save menu. 2. Choose the *DESTINATION* location (`P001-P100`) and optionally assign a custom *NAME*. 3. Press **Apply** again to confirm. ![Program selection](display_SAVE.png) ## Zone edit 1. Long Press on a ***Zone button*** to edit that zone. 2. Press the Main Encoder **left** or **right** to toggle between: - ***CONTROLS*** page, which displays the controls currently assigned to the four encoders. - ***SETTINGS*** page, where you can edit all of the zone parameters. ![Program selection](zoom.png) Move the Main Encoder **up and down** to select the parameter and **rotate** to change the value. | Zone parameters | Possible values | |:-------------------|:--------------------------------------------| | *ZONE STATUS* | `Off`, `On`, `Mute` | | *ZONE NAME* | Type the value | | *MIDI PORT* | `USB`, `DIN` | | *CHANNEL* | 1-16 | | *BANK MSB* | `OFF`, 0-127 | | *BANK LSB* | `OFF`, 0-127 | | *PROGRAM CHANGE* | `OFF`, 1-128 | | *VOLUME* | `OFF`, 0-127 | | *OCTAVE SHIFT* | ±4 | | *TRANSPOSE* | `Global`, ±12 semitones | | *VELOCITY CURVE* | `Global`, `Normal`, `Hard`, `Soft`, `Fixed` | | *FIXED VELOCITY* | 0-127 | | *AFTERTOUCH* | `Global`, `Off`, `On` | | *PEDAL 1 FUNCTION* | `Global`, `OFF`, CC1-119 | | *PEDAL 2 FUNCTION* | `Global`, `OFF`, CC1-119 | | *PEDAL 2 MIN/MAX* | `Global`, 0-127 | | *PEDAL 3 FUNCTION* | `Global`, `OFF`, CC1-119 | | *PEDAL 3 MIN/MAX* | `Global`, 0-127 | | *STICK 1 FUNCTION* | `Global`, `Off`, `On` | | *STICK 2 FUNCTION* | `Global`, `OFF`, CC1-119 | | *KNOB 1 CONTROL* | `OFF`, CC1-119 | | *KNOB 2 CONTROL* | `OFF`, CC1-119 | | *KNOB 3 CONTROL* | `OFF`, CC1-119 | | *KNOB 4 CONTROL* | `OFF`, CC1-119 | | *INITIALIZE* | | ## DAW Mode SL MK2 lets you control your DAW directly from the panel.

Some DAWs require the installation of an additional component. ## App Mode Press the **App Mode button** to control third-party apps directly from the SL. Studiologic has developed a completely new protocol called *SL LINK* to manage all the functions of connected compatible apps. The first public compatible app is [Studiologic Numa Player](/products/numaplayer/). Available operations with Numa Player: - Open a specific program with the Main Encoder. - Select a specific part with the zone buttons. - Mute and unmute a part. - Navigate through the app sections (*parameters*, *settings*, *effects*, *master*) by long pressing the zone buttons. ![](display_AVAILABLE_APP.png)    ![](display_APP_HOME.png)   ![](display_APP_EFFECTS.png)    ![](display_APP_MASTER.png) ## Global settings Press the **Global Setting button** to enter or exit from the Global Settings page. Global settings are automatically saved and are not linked to Programs. ![global settings pags](display_SETTINGS.png) ### Firmware version The page subtitle indicates the installed firmware version. [Firmware release notes and update procedure](/support/articles/slmk2-firmware/) ### MIDI version The right side of the screen shows the current MIDI version. SL MK2 automatically sets the MIDI protocol version based on the compatibility with the connected device. MIDI 2.0 is the latest evolution of the Musical Instrument Digital Interface (MIDI) protocol, designed to provide more expressive and flexible communication between digital musical instruments, software, and other devices. Building on the foundational MIDI 1.0 standard that has been in use since 1984, MIDI 2.0 introduces a number of improvements, including higher velocity resolution, increased control capacity, and better integration with modern technology. It allows for more nuanced performances and supports new features such as MIDI Capability Inquiry (MIDI-CI), Property Exchange and Universal MIDI Packet (UMP). Backward compatibility with MIDI 1.0 devices is guaranteed, making it a significant step forward in music production and performance. ### Setting list Use the Main Encoder **up/down** to scroll through the parameters and **rotate** to change the value. | Global parameter | Description | Possible values | |:-------------------------|:--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:-----------------------------------------------------------------| | *TRANSPOSE* | Transpose the instrument to any other key. | ±12 semitones | | *VELOCITY CURVE* | You can select different velocity curves, according to your taste and playing technique. | `SOFT`, `NORMAL`, `HARD`, `FIXED` | | *VELOCITY FIXED* | Set the value when *VELOCITY CURVE* is set to `FIXED`. | 1-127 | | *KBD SENSITIVITY* | You can adjust the sensitivity, relatively to the current curve. | -25% (heavier) / +25% (lighter) | | *KEY SENSITIVITY* | Press a key on the keyboard and adjust the sensitivity. | -30% (heavier) / +30% (lighter) | | *KBD B/W BALANCE* | Change the balance between black and white keys of the built-in keyboard. | ±15% | | *AFTERTOUCH* | Enable or disable the Aftertouch on the built-in keyboard. | *OFF*, *ON* | | *AFTERTOUCH SENSITIVITY* | Adjust the Aftertouch sensitivity on the built-in keyboard. | -32% (heavier) / +32% (lighter) | | *PEDAL 1 TYPE* | Set the pedal type for *PED 1* connection. | `SWITCH A`, `SWITCH B` | | *PEDAL 1 FUNC* | Assign a function to Pedal 1. | `OFF`, CC1-119 | | *PEDAL 2 TYPE* | Set the pedal type for *PED 2* connection. | `SWITCH A`, `SWITCH B`, `CONTINUOUS A`, `CONTINUOUS B` | | *PEDAL 2 FUNC* | Assign a function to Pedal 2. | `OFF`, CC1-119 | | *PEDAL 2 MIN/MAX* | Set a range to Pedal 2. | 0-127 | | *PEDAL 3 TYPE* | Set the pedal type for *PED 3* connection. | `SWITCH A`, `SWITCH B`, `CONTINUOUS A`, `CONTINUOUS B`, `SLP3-D` | | *PEDAL 3 FUNC* | Assign a function to Pedal 3.
