Supported plug & play MIDI controllers

Zynthian can be connected to almost any existing MIDI device and you can use the MIDI learning mechanism, as described in the [Zynthian_UI_User_Guide_-_V1/V4|UI user's guide], to assign parameters to faders and knobs in your MIDI controller, for instance. You could also assign pad trigger to notes, etc. But MIDI learning process takes time, it's limiting and you can't get feedback easily. Sometimes it's a lot better to plug a well-known (supported) MIDI controller and get everything mapped automatically. For having this, zynthian implements a controller driver API that allows developers to create specific drivers for specific devices.

This section contain documentation for some of this controller drivers.

Note:

This documentation is valid for the "chain_manager" development branch. It's only partially valid for the current testing branch so you could find some differences.

1 Akai APC Key25 MK2

This device supports two operation modes:

The default mode (called "Mixpad" in this section), which controls the ZynMixer and the ZynPad.
The "Device" mode, which handles the Zynthian UI.

1.1 Key notation

1.2 The Mixpad mode

This is the default mode, selected automatically on start. You can also change to it pressing SHIFT + VOLUME or SHIFT + PAN. In this mode you can perform the following actions:

Change controllers' bank. There are two banks (1 and 2), which are used to handle up to 16 chains (with the eight track buttons/knobs). Bank 1 is for chains 1 to 8 and bank 2 manage chains 9 to 16. To show current selected bank, press and hold SHIFT. One of the track buttons LEFT arrow or RIGHT arrow will light up in red, LEFT arrow is bank 1 and RIGHT arrow is bank 2. You can also press one of these buttons while holding SHIFT to change the bank.

Use track buttons to perform a function on chains. The function is chosen by pressing SHIFT + one of SELECT, MUTE or SOLO soft key buttons. Press and hold SHIFT to see current selected function on soft key buttons (in green). Functions are:
- SELECT, used to change the selected chain. The key bed (black and white keys) will play on that chain.
- MUTE, used to mute the corresponding chain.
- SOLO, used to enable solo in the corresponding chain.

Change current scene using the track buttons. You need first to select that function by pressing SHIFT + REC ARM buttons. This function is affected by bank selection, so you can change up to 16 scenes. When selecting a new scene, the ZynPad will be shown.

Start/stop all sequences of a row, pressing the corresponding SOFT KEY (without modifiers). If there are any sequence playing, it will stop them. If there are no sequences playing, it will start all of them at once. The action to be run is shown by the LED status (lit will stop, off will start).

Use knobs to modify chains' volume or balance. The value modified is given by current KNOB CTRL selected: VOLUME or PAN (for balance). To change the function, press SHIFT + VOLUME or SHIFT + PAN. The knobs are also affected by current controller's bank.

Use SHIFT + KNOB k1 to change volume or balance for main chain (will change the current KNOB CTRL function).

Press SHIFT + STOP ALL CLIPS to perform the selected track's function (MUTE or SOLO) on main chain.

Toggle audio playback with PLAY/PAUSE button. If Zynthian's ALT mode is active, it will toggle MIDI playback.

Toggle audio record with SHIFT + RECORD button. If Zynthian's ALT mode is active, it will toggle MIDI recording.

Tap a pad to start/stop a sequence. The status codes are as follows (pad color will always match the sequence color):
- Dim solid: Stopped sequence without content (no notes in patterns).
- Bright solid: Stopped sequence with content.
- Blinking slow: Playing sequence.
- Blinking fast: Recording sequence.
- Pulsing: Syncing to play/stop.

Stop all sequences (but not audio/midi playback or recording) pressing STOP ALL CLIPS button.

Open the pattern editor for a given sequence, pressing SHIFT + a pad button.

Start recording a pattern. For this, press RECORD + a pad button, which will 1) select the chain associated with the group of the sequence, 2) open the pattern editor for that sequence, 3) start playing the sequence and 4) start recording that sequence. If you press the pad again (without holding any other button), the recording will stop. Press again to stop playback too. You can also control the playback/recording with PLAY/PAUSE and RECORD buttons.
