Manual : Matrix Sampler

Matrix Sampler

The Matrix Sampler can load up to 16 audio samples. They can be played using the Matrix scherm-MIDI Keyboard, for example.

A 4x4 matrix of cells appears on the left. On clicking one of the 16 cells, the corresponding controls appear on the right. The Load button allows for loading samples. Several options are available:

Import: imports an audio file.
Paste: Pastes data copied from an audio or MIDI track editor.
Remove: removes sample.

In addition, you can copy from one cell to another using drag-and-drop. Dropping a file onto a cell is also possible. Samples can be up to 6 seconds in length. If you have longer samples, you can consider slicing them into parts using a track editor, the parts can then be loaded into multiple cells using the paste option.

The text box next to the Load button shows the name of the cell and allows for changing it. The name appears in the cell itself if a sample is loaded.

Volume controls the volume of the sample. Semitones and Cents control the pitch. Stretch can be used to make the sample shorter or longer so it matches the song tempo. The box accepts fractions, so you can type "120/80" instead of "1.5" to make a 120 BPM sample match your 80 BPM song, for example. If Oneshot is engaged, the sample will play all the way to the end regardless of note-off messages.

You can use the play button to play back the sample.

The Matrix Sampler responds to messages on all MIDI channels, so the Channel value typically doesn't matter. It does matter if you're recording using the MIDI Keyboard Mapper's split option or multiple keyboards: in these situations, you'll want only messages received on this channel to be recognized.
