Helix, Rack, LT

MIDI Bank/Program Changes

Helix responds to traditional MIDI CC and Program change messages from an external MIDI device (or from MIDI software via USB) and will recall setlists, presets, and/or snapshots accordingly.

Remotely Selecting a Setlist, Preset, and/or Snapshot

Press PRESETS to open the Setlist menu:

The dark text above Knob 2 displays the required MIDI messages for recalling the Helix device's setlists, presets, and/or snapshots from external MIDI devices or software. In the illustration above, the FACTORY 1 setlist is recalled with a CC32 message of 007, the 16B Bottle Message preset is recalled with a PC (program change) message of 005, and SNAPSHOT 1 is recalled with a CC69 message of 000.

MIDI Clock Send and Receive

Helix can send and receive MIDI clock via its MIDI 5-pin in/out, as well as via USB. MIDI Clock options can be enabled and configured within the "Global Settings > MIDI/ Tempo" options.

MIDI Clock Send: Transmit MIDI clock to synchronize the tempo of external pedals, rack gear, and software to the current Helix TAP Tempo rate.

MIDI Clock Receive: Synchronize the Helix time-based effects (such as delay and modulation) to incoming MIDI clock from external DAW software, drum machines, keyboard workstations, or other modelers. Note that the Helix TAP footswitch will flash blue (instead of the default red) to indicate the incoming tempo rate when receiving MIDI clock.

MIDI CC

Helix has reserved specific MIDI CC messages for global functions; these CCs cannot be used as controllers. If you attempt to learn a CC message reserved for global functions (see "Controller Assign"), the following dialog appears:

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. Conveniently enough, HX Stomp and HX Stomp XL have handy helper text to tell you exactly which MIDI messages will recall the current preset and snapshot.

1. If not already there, press HOME VIEW to select Play view.
2. Press the Upper Knob to open the Preset list:

The dark text above Knob 3 displays the required MIDI messages for recalling presets and/or snapshots from external MIDI devices or software. In the illustration above, the 16B Pastor of Muppets preset is recalled with a PC (program change) message of 061, and Snapshot 1 is recalled with a CC69 message of 000.

Block Bypass via MIDI

1. Press < PAGE and PAGE > together to open the Menu.
2. Press Knob 1 (Bypass Assign).
3. Turn the Upper Knob to select the block whose bypass you want to assign to incoming MIDI.
4. Press PAGE > and then Knob 3 (Learn). Send a MIDI CC message from your foot controller, keyboard, etc.

The CC number appears above Knob 1 (MIDI In).

Incoming CC values 0-63 turn the block off; values 64-127 turn the block on. Note that some MIDI CCs are reserved for global functions and cannot be selected (see "MIDI CC").

Parameter Control via MIDI

1. From Edit view, press and hold the knob for the parameter you wish to control.

HX Stomp and HX Stomp XL jump to the Controller Assign page and displays your parameter at Knob 1 (Parameter).

2. Press PAGE > and then Knob 3 (Learn). Send a MIDI CC message from your foot controller, keyboard, etc.

The CC number appears above Knob 3 (CC#).

3. If desired, press PAGE > and turn Knob 1 (Min Value) and Knob 2 (Max Value) to set the range you wish to control.

4. Press HOME when finished. Remember to save your preset to retain all assignments!

Synchronizing Tempo via MIDI

Certain Delay and Modulation parameters such as Time and Speed can be represented with fixed numeric values (ms or Hz) or note values (1/4-note, dotted 1/8-note, etc.). When set to note values, the parameter will follow Tap Tempo or incoming MIDI clock. Press the parameter knob to toggle between ms (or Hz) and note values.

By default, HX Stomp and HX Stomp XL respond to MIDI clock received from external gear (or your DAW software via USB). HX Stomp and HX Stomp XL can also transmit MIDI clock to external gear or software (transmit is disabled by default). MIDI clock reception (Rx) and transmission (Tx) can be enabled or disabled from the "Global Settings > MIDI/Tempo" menu.

In addition, certain modulation effects have distinct rhythmic elements; for example, a tremolo set to a square wave (sometimes called a "slicer") not only has a tempo but a beat, where the upswing of the wave lands with relation to your song. That is, the effect may be in perfect tempo-sync with your song, but its "downbeat" may be shifted ahead or behind of your drummer's-or in the studio-your recorded song's downbeat.

Press TAP once on the downbeat of your song.

Any beat sync-based (sometimes called "LFO") effects reset from the beginning.

HX Effects

The HX Effects device receives and transmits MIDI messages via its 5-pin MIDI In & Out connectors, as well as via USB, providing functionality with just about any MIDI hardware or software gear you may want to use with it. USB MIDI operation is functional with Mac & Windows computers, as well as with iPad or iPhone mobile devices.* Also see "Global Settings > MIDI/Tempo" for MIDI device options.

Preset Recall via MIDI

To recall a preset, send a program change (PC) message to your HX Effects device on MIDI channel 1, according to the table below.

Snapshot Recall via MIDI

To recall a snapshot, send the HX Effects hardware a CC69 message according to the table below.

Block Bypass via MIDI

1. Press to open MENU.
2. Press the SIGNAL FLOW switch.
3. Turn the Big Knob to select the block for which its bypass you want to assign to incoming MIDI.
4. Press > and turn Knob 3 (MIDI Bypass) to assign an incoming MIDI CC message to turn the block on and off.

Incoming CC values 0-63 turn the block off; values 64-127 turn the block on. Note that some MIDI CCs are reserved for global functions and cannot be selected.

Parameter Control via MIDI

1. From Stomp mode, press and hold the knob 1~3 for the parameter you wish to control.

The HX Effects device jumps to the Controller Assign page and displays your parameter at Knob 1 (Parameter).

2. Press the LEARN switch and then send a MIDI CC message from your foot controller, keyboard, etc.

The CC number appears above Knob 3 (CC#).

3. If desired, press and turn Knob 1 (Min Value) and Knob 2 (Max Value) to set the range you wish to control.

4. Press HOME to return to the Home screen.

MIDI Clock Send and Receive

HX Effects is able to send and receive MIDI clock via its MIDI 5-pin in/out, as well as via USB. MIDI Clock options can be enabled and configured within the "Global Settings > MIDI/Tempo" options.

MIDI Clock Send: Transmit MIDI clock to synchronize the tempo of external pedals, rack gear, and software to the current HX Effects TAP Tempo rate.

MIDI Clock Receive: Synchronize the HX Effects time-based effects (such as delay and modulation) to incoming MIDI clock from external DAW software, drum machines, keyboard workstations, or other modelers. Note that the HX Effects TAP footswitch will flash blue (instead of the default red) to indicate the incoming tempo rate when receiving MIDI clock.
