Use your Spark Control X as a MIDI foot controller.

What it does

• Six switches, any message

  Each switch sends a CC, momentary or toggle, a note or a program change. Holding a switch can send something else, and pressing two switches together is a trigger of its own.

  II→CC 81 = 127 · ch 1

• Two expression inputs

  Plug TRS expression pedals into EXP 1 and EXP 2. Set heel and toe in Flintstep and invert the direction if you need to. Each input can also act as a switch: it fires when the pedal leaves the heel, or when you click the toe down.

  EXP 1→CC 11 = 0 to 127 · ch 1

• LEDs your DAW can drive

  A switch lights while you hold it and while its toggle is on. Or turn on MIDI feedback: send the same CC back to the Flintstep LEDs (Spark Control X) port and the LED shows the real state, like a plugin bypassed or a track armed. The AMP and APP lamps can show MIDI traffic, the connection or USB power.

• Presets

  Keep a mapping per DAW or per gig and switch between them from the menu bar. Each preset has its own undo history. Export one as a file to use it on another Mac.

  

• Nothing else to install

  No Spark app, no amp, no firmware update. Flintstep never writes to the profiles stored on the pedal. It remembers your pedal, reconnects on its own, and shows the battery level and charging in the menu bar.

How it works

1. Turn the pedal on

   Keep the Spark app closed. The pedal talks to one app at a time.

2. Open Flintstep

   It finds the pedal and connects. macOS asks for Bluetooth access the first time. After that Flintstep stays in the menu bar.

3. Map it in your DAW

   Pick Flintstep (Spark Control X) as a MIDI input and use MIDI learn, or change the messages in Flintstep to match what your DAW expects.
