Getting started

MidiQ is a browser-based MIDI editor for Behringer BCR2000 and BCF2000 controllers. It uses the Web MIDI API to communicate directly with your hardware - no drivers or plugins required.

1. Open MidiQ in a supported browser (Chrome, Edge, or Opera).
2. Connect your BCR2000 or BCF2000 via USB or a standard DIN MIDI interface.
3. Click the Settings icon (gear) in the left rail, select your MIDI input and output ports, and click Connect.
4. Click any encoder, button, or fader on the virtual hardware to open the element editor and configure its MIDI assignment.
5. Send the preset to your device using the Send to device button in the bank panel, or export it as a BCL/SysEx file.

BCEditor is designed to configure your B-Control unit - it is not a controller. The physical function keys on the device (STORE, LEARN, EDIT, EXIT) and other BC function buttons are hardware operations; BCEditor intentionally does not emulate or trigger them.

No account is required to use the editor. Create an account to save presets to the cloud, organize them in banks, and import/export files.

MIDI connection

USB vs DIN MIDI

The BCR2000 and BCF2000 can connect in two ways:

• USB - Plug directly into your computer. This is the simplest option and works on Windows and Linux without additional hardware. On most Macs it works as well - see the note about Apple Silicon below.
• DIN MIDI (5-pin) - Connect via a standard MIDI interface (USB-to-MIDI adapter or audio interface with MIDI ports). This is the most reliable option on all platforms, including Apple Silicon Macs.

Settings panel

Click the Settings icon (gear) in the left rail to open the Settings panel.

• In port / Out port - Select the MIDI ports matching your BCR/BCF device.
• Connect - Opens the selected ports. The status indicator in the toolbar turns green when connected.
• Refresh - Rescans available MIDI ports after you connect or disconnect hardware.
• SysEx Delay - Optional delay (ms) between SysEx messages. May help on some setups; not effective for the Apple Silicon USB issue described above.
• Model / Firmware - Read-only fields showing device info received after connecting.

MIDI port preferences are saved automatically when you are logged in.

Global device setup

Global Setup contains settings stored by the hardware rather than in one preset. Expand it in Settings to edit:

• Device ID (1–16) - Selects which device responds on a shared MIDI connection.
• MIDI mode (U-1 to U-4 USB or S-1 to S-4 DIN) and receive channel - Controls routing and Program Change reception.
• Foot switch polarity and startup preset - Configure pedal wiring and the preset loaded at power-on.
• Transmission interval and dead time - Tune message timing and encoder/fader debouncing.

Click Send Global to Device to transmit these settings immediately. The toolbar Panic Reset sends All Notes Off and Reset All Controllers on all 16 MIDI channels.

BCR2000 & BCF2000

Use the ROTARY / FADER toggle on the right side panel to switch between device models. This changes the virtual layout without affecting the preset data.

Both models share the same preset format. Faders on the BCF2000 are internally mapped to encoders 33–40. Drag an encoder or fader to change its value; click a button to trigger its configured momentary, toggle, or increment behavior.

The LED display shows the active preset and can show an element value when Show value is enabled. The status LEDs indicate incoming MIDI, outgoing DIN activity, foot-switch presses, and the current mode. B49–B52 are user-configurable buttons; B61/B62 are foot-switch inputs, with the BCF2000 also exposing a continuous foot controller.

Element editor

Click any encoder, fader, or button on the virtual hardware to select it and open the editor panel on the right.

Common fields

• Name - A label displayed on the virtual element (up to 24 characters).
• Type - The MIDI message type. See MIDI types below.
• Channel - MIDI channel 1–16.
• Min / Max - Output value range. For CC and NRPN this supports 14-bit values (0–16383) when used with 14-bit modes.
• Default - Value sent when the element is reset (CC only).
• Show value - Display the current value numerically on the element.
• Color - A color dot for visual grouping.
• Reset - Resets all parameters on this element to default.

Encoder-specific fields

• Mode - Absolute or Relative, in 7-bit or 14-bit resolution. Relative variants: 1 (signed bit), 2 (two's complement), 3 (sign-magnitude).
• LED - How the LED ring visualizes the value. See LED ring modes below.
• Resolution - Encoder steps per rotation (1–65535).

Button-specific fields

• Mode - Momentary: sends value on press and release. Toggle: latches on/off. Increment: each press adds or subtracts a step value.
• Step - Step size for Increment mode (-127–127, excluding 0).

BCL code view

Click the toggle button in the editor header to toggle the BCL code editor, which shows the raw BCL lines that will be sent to the device for the selected element. The editor is fully editable: each line is validated as you type, with line numbers and red highlights marking syntax errors. When the code is valid, your changes are applied to the element automatically. The form-based editor below will reflect them when you switch back.

Changes are saved automatically. Use Ctrl+Z to undo and Ctrl+Y / Ctrl+Shift+Z to redo.

MIDI types

Encoder groups

The top row of 8 push encoders supports up to 4 independent groups, effectively giving you 32 configurable encoders in the same physical row. Click the 1 / 2 / 3 / 4 buttons on the right side panel to switch the active group. The LED display shows the active group.

Each group stores its own MIDI assignments independently. The dedicated encoders and buttons (rows below) are not affected by group switching.

Group buttons 1–4 can be reprogrammed like other buttons: select the group button and change Type to SysEx or another MIDI type. This frees that button for custom messages, but reduces the number of hardware encoder groups available.

LED ring modes

Push encoders and dedicated encoders have a 15-segment LED ring. The LED field in the element editor controls how it displays the current value:

Drag & drop

Rearrange element assignments by dragging them on the virtual hardware:

• Swap - Drag one element onto another to swap their configurations.
• Insert - Hold Shift while dropping to insert and shift subsequent elements down by one position.
• Copy - Hold Alt (or Ctrl) while dropping to copy the source element instead of moving it.
• Multi-element drag - Select multiple elements first (Ctrl+click or Shift+click range), then drag the group.

Banks & presets

Presets are organized into banks. Click the Banks icon (folder) in the left rail to open the banks panel.

• Each bank holds up to 32 numbered preset slots.
• Click a preset slot to load it into the editor.
• Double-click a bank or preset name to rename it. Use a bank's trash icon to delete it when available.
• Drag a preset onto another slot to swap them. Hold Alt or Ctrl while dropping to copy instead.
• Use the active preset panel to copy, paste, or reset the loaded preset. Reset clears its assignments but keeps the slot.
• Use Recv and Send to transfer the active preset to or from the device's temporary memory.
• Click the export icon next to a bank name to download all presets in that bank as a single file.
• Create a new bank with the + button in the banks panel header.

Import & export

• Import - Click the import icon in the banks panel header to load a preset file. Supported formats:
  • .syx - Binary SysEx (Behringer factory files and BC Manager exports)
  • .bcr - BCL text preset for BCR2000 (BC Manager)
  • .bcf - BCL text preset for BCF2000 (BC Manager)
  • .bc2 - BC Manager project file (BCL text)
  • .txt - Plain BCL text
• Export preset - Click the export icon on a preset slot to save it as a file. BCR2000 presets export as .bcr, BCF2000 presets as .bcf. Both are plain BCL text files and can be opened in any text editor.
• Export bank - Click the export icon next to a bank name to save all presets in that bank as a single .bcr or .bcf file, depending on the active device model.

Imported files are automatically detected as BCR2000 or BCF2000 from the file header or extension. The model can be overridden after import.

SysEx transfer

BCEditor uses the BCL (B-CONTROL Language) protocol over SysEx to read from and write to the device. Transfer operations are available in the Banks panel:

• Send preset - Click the send icon (↑) on a preset slot to push that preset to the device's active (temporary) memory over SysEx.
• Receive preset - Click the receive icon (↓) on a preset slot to read the currently active preset from the device into that slot.
• Receive all - Click the receive icon next to the bank name to read all 32 presets from the device at once.

Transfer progress and any BCL responses are shown in the Log tab of the bottom panel.

On Apple Silicon Macs, USB SysEx is unreliable - see the Apple Silicon USB known issue note in the MIDI connection section.

MIDI monitor

The bottom panel can be expanded by clicking or dragging its top edge. It has two tabs:

• Log - Shows application events and BCL transfer output.
• MIDI Monitor - Shows all incoming and outgoing MIDI messages in real time. Each row shows: timestamp, port, direction, channel, type, parameter, and value.

Use the Filter button (funnel icon) in the MIDI Monitor tab to show/hide specific message types or directions. Use the Copy button to copy the current tab content to the clipboard.

Community presets

Open the Library panel to browse public presets. Search by preset name or author, filter by BCR2000/BCF2000 and minimum rating, and sort by name, model, author, date, or rating.

• Import a library preset into a local bank as an editable copy; the published original is unchanged.
• Rate presets from one to five stars, adjust or remove your rating, and open an author's profile to see their presets and bio.
• Use the visibility control on the active preset to publish it or keep it private. Free accounts publish publicly; Studio accounts can keep presets private.

Accounts & profiles

Register or log in from the top-right account menu to sync presets and access community actions. You can still edit locally without an account.

• Cloud banks and presets, the active bank/slot, MIDI preferences, and profile changes are saved to your account.
• Edit your display name, bio, and avatar from Edit Profile; uploaded avatars can be cropped before saving.
• The profile menu shows your Free or Studio tier and community rating badge. Email accounts can change their password; Google accounts manage authentication through Google.
• Log out to return to local browser storage. Cloud and community actions remain unavailable until you log in again.

Status & notifications

• The bottom status bar shows separate MIDI IN and MIDI OUT connection indicators. Click either indicator to open Settings.
• The hardware status LEDs show live activity and control state; the MIDI Monitor shows message details.
• Toast notifications in the top-right report saves, imports, connections, transfers, and errors.
• The top-right bell announces app updates. Its indicator clears when the updates menu is opened; it is separate from the preset Library.
