The Matrix Sampler can load up to 16 audio samples. They can be played using the Matrix onscreen keyboard for example.
A 4x4 matrix of cells appears on the left. On tapping one of the 16 cells the corresponding controls appear on the right. The Load button allows for loading samples. Several options are available:
- Import an audio file from AudioShare, the General Pasteboard or iTunes File Sharing.
- Paste data copied from audio or MIDI track editor.
- Remove.
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 playback the sample. This can come in handy while copying data from a tracks to cells, when there's not enough room for the matrix keyboard.
The Matrix Sampler supports the following MIDI messages:
- Note On/Off
- Volume (cont. 7)
- Expression (cont. 11)
