--- version: "Rev D_v1.3" language: "en" --- # MIDI Helix Stadium supports MIDI control via external MIDI DIN (the good ol' 5-pin connection) for a myriad of functions, including preset selection, block bypass, real-time parameter control, MIDI Clock sync, and more. Additionally, MIDI is transmitted and received via Stadium's USB-C using the options within your Stadium device's [**Global Settings \> MIDI**](https://manuals.line6.com/en/helix-stadium/live/global-settings.md#globals-midi) settings.^\*^ Stadium's MIDI Clock can be enabled or disabled using the [**Global Settings \> Tempo/Click \>**](https://manuals.line6.com/en/helix-stadium/live/global-settings.md#globals-tempo)**Receive MIDI Clock** and **Send MIDI Clock** options. ^**\***^**Note:** For USB MIDI operation when connected to a Windows^®^ computer, you must download and install the Helix Stadium ASIO^®^ driver, available from [**http://line6.com/software**](http://line6.com/software). (This driver is automatically installed with the Helix Stadium application, v1.2 and later, installation on Windows.) No driver installation is necessary for MIDI functionality with macOS computers or mobile devices. In this chapter, we'll cover external remote MIDI control of Helix Stadium functions. Many of Stadium's Global functions are pre-configured with MIDI CC commands, and block bypass and most block parameters can be custom-assigned either manually or via MIDI Learn and stored per preset. Refer to the lists of all Global MIDI CC mappings in the following sections. **Tip:** Helix Stadium is also highly functional as a MIDI controller device, allowing you to configure and send many types of MIDI (and other) commands to your external gear via 5-pin MIDI DIN or USB. See [**Command Center**](https://manuals.line6.com/en/helix-stadium/live/command-center.md). ## Preset and Snapshot Recall via MIDI MIDI can be frustrating enough as it is without having to slog through a manual to figure out what messages your particular device needs to change presets or snapshots. Conveniently enough, Helix Stadium provides handy helper text to tell you exactly which MIDI messages recall the current preset and snapshot. 1. **From the Home \> Edit screen, tap the Preset name in the header to open the Preset List** (below left). Alternatively, **tap the Snapshot icon to open the snapshot panel** (below right).The small text in the sidebar displays the required MIDI messages for recalling the current preset and snapshot from external MIDI devices or software. In the illustrations below: * The **3 Practice List** setlist is recalled with a CC32 (bank select) message of 7 * The **2D Simple Jack** preset is recalled with a PC (program change) message of 7 * The **1---INTRO** snapshot is recalled with a CC69 message of 0 ![Preset List MIDI Recall.png](https://manuals.line6.com/__attachments/a_0bbd5c45d70636ccbe8fb0afcd710b6e1447e53be0c52de08b080dfc5acb5e77/Preset%20List%20MIDI%20Recall.png?cb=711df938a291970851513873d9b5ca68) MIDI Recall CC/PC values in the Preset List ![image-20251115-020220.png](https://manuals.line6.com/__attachments/a_5e96508b5abde175e73966898ab6692b68a3f9de026bfcf07b6517fc0b4f963a/image-20251115-020220.png?cb=df70dd03dafa27d9b899bab190b3a886) MIDI Recall CC/PC values in the Snapshot panel In most cases, you do NOT need to send a CC32 message every time you recall a preset---**just send the PC message** . The exceptions are if you want to select a preset in a different folder or setlist---or, in the case of the USER PRESETS folder (as it contains 512 preset locations), if you want to select a preset in a *different group* of 128 presets. In this case, send the folder/group/setlist's CC32 message first, followed by the preset's PC message. Snapshots work in a similar way. To change snapshots in the same preset, **just send the corresponding CC69 value** (0 for Snapshot 1, 1 for Snapshot 2, 2 for Snapshot 3, etc.)---no need to send CC32 or PC messages. ### Bank and Program Change List | **Bank** | **CC32 Value** | **PC Value** | **Preset Locations** Preset numbers change depending on [**Global Settings \> Preferences**](https://manuals.line6.com/en/helix-stadium/live/global-settings.md#globals-preferences) **\> Preset Numbering**: ||| | **Bank** | **CC32 Value** | **PC Value** | |---------------------|----------------|--------------|-------------|------------|------------| | **1A-128D** | **0-511** | **1-512** | | **FACTORY PRESETS** | 0 | 0-XXX | 1A \~ XXX | 0 \~ XXX | 1 \~ XXX | | **USER PRESETS** | 1 | 0-127 | 1A \~ 32D | 0 \~ 127 | 1 \~ 128 | | **USER PRESETS** | 2 | 0-127 | 33A \~ 64D | 128 \~ 255 | 129 \~ 256 | | **USER PRESETS** | 3 | 0-127 | 65A \~ 96D | 256 \~ 383 | 257 \~ 384 | | **USER PRESETS** | 4 | 0-127 | 97A \~ 128D | 384 \~ 511 | 385 \~ 512 | | **Your Setlists** | 5-127 | 0-127 | 1A \~ 32D | 0 \~ 127 | 1 \~ 128 | **Note:** When navigating your saved Presets from the Helix hardware (Upper Knob, preset footswitches, Preset Up/Down, etc.), Helix Stadium automatically transmits a MIDI Program Change message to its MIDI DIN and USB MIDI Outs, corresponding to the selected preset. If you'd prefer Helix Stadium not automatically transmit PC messages, turn [**Global Settings \> MIDI**](https://manuals.line6.com/en/helix-stadium/live/global-settings.md) \> Send MIDI PC off. Please also note that "Empty" presets in the USER PRESETS folder or a Setlist that have not yet been saved do not transmit a MIDI PC message when selected. Likewise, Empty presets cannot be recalled via MIDI PC unless they have been saved first. ## MIDI Clock Helix Stadium can receive and send MIDI Clock via its MIDI DIN In/Out as well as via USB for tempo sync with external devices and software. **MIDI Clock Send** and **Receive** can be enabled and globally configured within the [**Global Settings \> Tempo/Click**](https://manuals.line6.com/en/helix-stadium/live/global-settings.md#globals-tempo) options. ![Temo_MIDIClock_Globals.png](https://manuals.line6.com/__attachments/a_68d8729114b32378304eb958bed9f8288070b56ec68cd42c95d313f97799cdbc/Temo_MIDIClock_Globals.png?cb=4afa61287af2edf50e5b1e13fa4fbee3) The Global MIDI Clock settings * **Receive MIDI Clock:** Receive MIDI Clock via MIDI In or MIDI USB In (or both) to synchronize Helix Stadium's time-based effects (such as delay and modulation) to external DAW software, drum machines, keyboard workstations, or other modelers. Note that the Helix Stadium TAP footswitch flashes blue when receiving MIDI Clock. * Receive MIDI Clock is set to **Auto** by default, so Stadium's tempo will automatically sync to MIDI Clock when received via USB-C or MIDI In. * **Send MIDI Clock:** Transmit MIDI Clock to MIDI Out or MIDI USB Out (or both) to synchronize the tempo of external pedals, rack gear, and software to the current Helix Stadium TAP Tempo or Song Tempo. (Note that the TAP Tempo vs Song Tempo behavior is determined by the[**Global Settings \> Tempo/Click \>**](https://manuals.line6.com/en/helix-stadium/live/global-settings.md#globals-tempo) **Follow Song Tempo** setting.) ## MIDI CC Helix Stadium has the potential of reserving so many specific MIDI CC messages for global functions such as bank select, snapshot select, looper functions, emulation of knobs, pedals, etc. (Ch 1 by default), there are not enough open CCs for meaningful assignment of block bypass or parameter control. So bypass/control assignment gets its own user-selectable MIDI channel (Ch 2 by default). You can change these from [**Global Settings \> MIDI \>**](https://manuals.line6.com/en/helix-stadium/live/global-settings.md#globals-midi)**Global MIDI Channel** and **Bypass/Ctrl MIDI Channel** , as long as they're not set to the *same* channel. ### Global CCs Click to display the Global CCs #### **Pedals, Footswitches, and Knobs** | **MIDI CC#** | **Value** | **Function** | |--------------|-----------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | **1** | 0-127 | Emulates EXP 1 Pedal | | **2** | 0-127 | Emulates EXP 2 Pedal | | **3 \~ 6** | -- | *Reserved for potential future use* | | **7** | 0-127 | XY Controller, X-Axis (0 = bottom of the screen) | | **8** | 0-127 | XY Controller, Y-Axis (0 = left edge of the screen) | | **9** | 0-34^\*^ | Emulates pressing a top panel button, pressing a More Mode switch, or tapping an onscreen icon: 0=Home View, 1=Song View, 2=Amp, 3=Save Screen, 4=XY Open/Close, 5=\, 7=Matrix 1/4" Open/Close, 8=Matrix XLR Open/Close, 9=Matrix Phones Open/Close, 10=Undo, 11=Redo, 12=Preset Down, 13=Preset Up, 14=Preset List Open/Close, 15=Preset Info Open/Close, 16=Info Scroll Up, 17=Info Scroll Down, 18=Info Zoom In, 19=Info Zoom Out, 20=Preset Clip Open/Close, 21=Stopwatch Start/Stop, 22=Stopwatch Reset, 23=Click On/Off, 24=Mute All On/Off, 25=Focus panel Open/Close, 26=Song List Open/Close, 27=Flag List Open/Close, 33=Song Settings Open/Close, 34=Tuner Open/Close ^**\***^**Note: Values 28\~32 have no assigned function.** | | **11 \~ 35** | -- | *Reserved for potential future use* | | **36** | 0-127 | Emulates Toe Switch (alternates switch state on each send of any value) | | **37** | 0-6 | Footswitch Mode (0=Stomp A, 1=Stomp B, 2=Preset, 3=Snapshot, 4=Combo, 5=Unassigned, 6=Transport) | | **38** | 0-127 | Emulates Knob 1 | | **39** | 0-127 | Emulates Knob 2 | | **40** | 0-127 | Emulates Knob 3 | | **41** | 0-127 | Emulates Knob 4 | | **42** | 0-127 | Emulates Knob 5 | | **43** | 0-127 | Emulates Knob 6 | | **44** | 0-127 | Emulates Knob 7 | | **45** | 0-127 | Emulates Knob 8 | #### Transport Control **Tip:** Playlists and songs can be recalled via MIDI CC, and Stadium makes it really easy to see what messages to send. **From Song view, tap the song's name to open the Song List.** The MIDI CC messages used to recall the current playlist and song are displayed at the bottom of the right sidebar: ![SongList_MIDIRecall.png](https://manuals.line6.com/__attachments/a_41deb7fad791757471af4ab2f675988f59c25abb07aa4fb9de989e7bd6fef0ce/SongList_MIDIRecall.png?cb=18905911d0108e158ecf68209b1fcd33) Song List MIDI Recall Info * **Playlist**: CC63, values 0-127 (SONG LIBRARY is value 0; each subsequent playlist is value 1-127) * **Song**: CC10, values 0-127 | **MIDI CC#** | **Value** | **Function** | |--------------|-------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | **10** | 0-127 | Cues a song within the current Playlist (0=first song, 1=second song, 2=third song, etc.) | | **63** | 0-127 | Selects a Playlist and cues its first song (0=the main SONG LIBRARY folder, 1=Playlist 1, 2=Playlist 2, etc.) | | **46** | 0-127 | Cues a Marker flag within the current song (0=song's Start flag, 1=Marker 1, 2=Marker 2, etc.) | | **47** | 0-127 | Return to Zero (any value) | | **48** | 0-63: Clear Cycle (or, create a Cycle between markers) 64-127: Cycle Enable/Disable | If a Cycle exists, 0-63 will clear it.

Use the Bypass/Control screen's MIDI CC and MIDI Learn options to create your own custom MIDI CC assignments to your block bypass and parameter control. Bypass/Control CCs are saved per preset. * To assign block bypass to a MIDI CC, see [**Quick Stomp Bypass Learn Assign**](https://manuals.line6.com/en/helix-stadium/live/bypass-and-controller-assign.md). * To assign parameter control to a MIDI CC, see [**Quick Controller Assign**](https://manuals.line6.com/en/helix-stadium/live/bypass-and-controller-assign.md). ^**\***^**Note:** You can set a different MIDI Channel from [**Global Settings \> MIDI \>**](https://manuals.line6.com/en/helix-stadium/live/global-settings.md#globals-midi) **Bypass/Control MIDI Channel**. You should always choose a different MIDI Channel than the one used for Global functions.
