55 * engine channels. The engine channels Borrow() instruments when they
56 * need them and HandBack() when they don't need them anymore. The
57 * InstrumentResourceManager loads the corresponding sfz file and sfz
58 * instrument if needed, if it's already in use by another engine
59 * channel, then it just returns the same resource, if a sfz
60 * instrument / file is not needed anymore, then it will be freed from
61 * memory.
