synthesizer.instruments.instrument_collection

A module defining a container for instruments.

A InstrumentCollection is a container for Instrument objects. It can be treated as a dictionary of instruments, with the label of the instrument as the key. It can also be treated as an iterable, allowing for simple iteration over the instruments in the collection.

InstrumentCollections can either be created from an existing file or initialised as an empty collection to which instruments can be added.

Example usage:

# Create an empty InstrumentCollection collection = InstrumentCollection()

# Add an instrument to the collection instrument = Instrument(label=”my_instrument”, …) collection.add_instruments(instrument)

# Add multiple instruments to the collection instrument1 = Instrument(label=”instrument1”, …) instrument2 = Instrument(label=”instrument2”, …) collection.add_instruments(instrument1, instrument2)

# Save the collection to a file collection.save_instruments(“path/to/file.hdf5”)

# Load the collection from a file collection = InstrumentCollection(“path/to/file.hdf5”)

# Iterate over the instruments in the collection for instrument in collection:

print(instrument.label)

# Get an instrument by its label instrument = collection[“my_instrument”]
