You can import your own samples into Liquid Rhythm using two different methods. You can drag and drop .wav samples into the arranger to create voice/instrument tracks or you can use the Instrument Editor that allows multi-layered samples. Dragging and dropping the samples into the session requires you to use the “Consolidated Save” function. Creating Instrument Voices with the editor will embed your samples into the library.
More information about the Instrument Editor can be found on Page 32 in the Liquid Rhythm Manual
