Introduction

About the MIDI C6

The MIDI C6 controller is designed to simplify the control of one or several MIDI devices. It is fully configurable, which means you can customize it to your preferences. It has a total of 24 scenes that let you adapt the controller in many different ways.

The C6 controller buttons have a light ring that can be set to a custom color, with a selection of 15 colors available.

The C6 buttons can perform three types of actions: normal click, double click and long click. These actions are fully configurable: you choose which message to send and which color the light ring uses.

Each action of the Kowka MIDI C6 can be customized to send up to 5 MIDI messages with a single click. These MIDI messages can be sent on different channels of your choice, allowing you to control an unlimited number of devices with the C6.

The controller display is 3.2 inches and color, ensuring the controller information is visible even in low-light conditions, providing details about the current configuration of the device.

The C6 features MIDI OUT, USB, USB Host and Bluetooth outputs. These allow you to control devices that receive USB messages, control VSTs on a computer via the USB connection, as well as devices with host reception.

The C6 also has a MIDI IN input to receive MIDI messages, which can come from a MIDI OUT output or from the available USB outputs.

It is also possible to connect two external expression pedals or two external two-switch footswitches using the EXP1/CTRL1 and EXP2/CTRL2 outputs.

Feature overview

The C6 has a total of 24 Scenes, each of which lets you save a complete controller configuration.

The following figure shows how each Scene is laid out.

Scene layout

Each event (see the Glossary for details) inside the C6 can be configured with the following features:

  • Custom event name with a maximum of 11 characters. This message is shown when the event runs.
  • Event color among the 15 available colors.
  • Ability to send up to 5 different messages. These MIDI messages can be sent on different channels, letting you change parameters on several devices at the same time.

When you send a MIDI message through the C6, it is transmitted via MIDI OUT, USB MIDI, Bluetooth MIDI and USB Host MIDI. On USB Host, the MIDI message is sent on MIDI channel 1.

Scenes

A scene in the C6 is a complete controller configuration, including the external expression pedals.

You can configure the scene with the following parameters:

  • Scene name: each scene can have a specific name with a maximum of 11 characters.
  • Ability to send 5 MIDI messages when loading a scene. These messages let you customize the different devices when this scene loads.
  • Define the Program Change range the scene will move within. The values range between 0 and 127.

Global settings

The C6 controller offers several global configuration options for the whole device.

  • Default MIDI channel: this selected channel will be used for sending all messages, although you can choose other channels to send MIDI messages. This channel is also shown on the controller screen along with its current Program Change (PC) value.
  • Default scene: this is the scene that loads automatically when the controller powers on.
  • Maximum number of scenes: you can adjust the maximum number of available scenes to your needs. If you only need 4 scenes, there is no need to have all 24 scenes available on the controller.

External footswitches

The MIDI C6 controller allows the use of 2 external expression pedals or 2 external footswitches, or one external expression pedal and one external footswitch.

To use these devices, you must enable them in the specific scene through the configuration app. You can select whether to enable the expression pedal, the footswitch, or keep them disabled.

Footswitch

The footswitch must be a two-button model with momentary (non-latching) switches. Connect it with a TRS signal cable.

The external footswitch has the same features as the C6 buttons, with normal click, double click and long click events, as well as the ability to assign a custom color and message.

Expression pedal

The C6 supports the use of one or two expression pedals. The connection must be made using a TRS signal cable. To calibrate the expression pedal, see the Expression pedal calibration section.

Expression pedal calibration

Enter the Kowka MIDI C6 settings menu by pressing buttons 3 and 4 at the same time.

Choose the option you prefer:

  • To calibrate expression pedal EXP / CTRL 1, press button 2) Calibrate expression Pedal#1
  • To calibrate expression pedal EXP / CTRL 2, press button 3) Calibrate expression Pedal#2

Connect the expression pedal to the corresponding input using a TRS cable.

Place the expression pedal at the minimum position (heel down, full weight on the heel). When at minimum, press button 1 on the device to set the MIN parameter.

Place the expression pedal at the maximum position (toe down, full weight on the toes). When at maximum, press button 1 on the device to set the MAX parameter.

If the calibration was successful, a confirmation message appears. If it failed, an error message appears — try the process again.

Host

The C6 includes a Host connection to control devices that do not automatically support USB OTG. Some of the devices with this option are:

  • Zoom MS-50G
  • Zoom G1xon
  • Hotone Ampero MINI
  • Hotone Ampero
  • Any other device with a USB Host connection

To make the connection:

  1. Make sure the device is powered off before connecting it.
  2. Connect a USB cable from the «Host» output of the C6 to the device you want to control.
  3. Once connected, power on the C6 first and then the device you want to control.
💡 Note: Remember that messages through the USB-Host port are only sent on MIDI channel 1.

Appendices

Glossary

Here is the glossary of terms used in this manual:

Click Normal: Pressing the footswitch once.

Click Doble: Pressing the footswitch twice. The interval between presses must be under 500 ms; otherwise the controller interprets two normal clicks.

Click Largo: Holding the footswitch pressed for more than 600 ms.

Evento: Type of action a controller footswitch can execute. The C6 has 3 different events.

Mensaje: MIDI instruction sent, or action within the controller. It can be a Program Change, Control Change, Note On, Note Off message or a scene change.

Firmware update

To update the firmware you will need a USB-C cable to connect directly to a computer. This lets you install new firmware versions with new features.

The steps are the following:

  1. Download the latest firmware version from kowka.com/downloads. On that page you can get the latest available firmware version.
  2. Unzip the firmware file into a folder for later installation on the Kowka MIDI C6.
  3. With the device disconnected from its power source and/or USB power, hold down button 4 on the controller and, without releasing it, connect the USB cable to the computer. If done correctly, button 4 of the Kowka MIDI C6 will be green and a new drive named “Kowka-C6” will open.
  4. After opening the “Kowka-C6” drive, copy the downloaded file into it. When the copy finishes, the new firmware will be installed automatically.

Once the copy finishes, the Kowka MIDI C6 will install the new firmware and restart automatically. Remember to validate the installation on the home screen, where the controller firmware version is shown.

💡 Tip: We recommend performing a factory reset when doing a firmware update.
