maxosc 0.0.6

Call python code from MaxMSP over OSC

MaxOsc is a package designed to conveniently call python code from MaxMSP over OSC. It's a wrapper of the python-osc package with a built-in parser.

The python code should be run independently of Max (in a terminal or similar) and can be used in conjuncture with the set of Max abstractions available here or directly through the CNMAT externals for OSC (also available through the Max package manager).

Project Status

Development of this project is largely stalled. Minor fixes will be released when necessary.

The project is stable but documentation is limited.

Minimal Example

Run the following code in a separate terminal. Note that MaxOsc.run() will instantiate a blocking OSC server, hence no code below that point will ever be executed.

from maxosc import MaxOsc

class Flipper(MaxOsc):

    def __init__(self):
        super().__init__()
        self.run()

    def flip(self, a1: int, a2: int):
        return a2, a1

    def flip_list(self, a: [int]):
        return list(reversed(a))

if __name__ == '__main__':
    Flipper()

If the pyosc abstractions are available in your path, the following Max patcher can be used:

Elaborate Example

Python Code:

from maxosc import MaxOsc


class Instrument:
    def __init__(self, name: str, midi_range: (int, int), supported_techniques: [str], concert_pitch: float,
                 transposing: bool):
        self.name: str = name
        self.midi_range: (int, int) = midi_range
        self.supported_techniques: [str] = supported_techniques
        self.concert_pitch: float = concert_pitch
        self.transposing: bool = transposing

    def max_getter(self):
        return self.name, self.midi_range, self.supported_techniques, self.concert_pitch, self.transposing


class InstrumentBank(MaxOsc):
    def __init__(self):
        super().__init__()
        self.instruments: [Instrument] = []
        self.run()

    def add_instrument(self, name: str, midi_range: (int, int), supported_techniques: [str],
                       concert_pitch: float = 440.0, transposing: bool = False):
        instrument = Instrument(name, midi_range, supported_techniques, concert_pitch, transposing)
        self.instruments.append(instrument)
        print(f"Added instrument '{name}' with range={midi_range}, techniques={supported_techniques}, "
              f"concert pitch={concert_pitch} and transposing={transposing}.")

    def get_instruments(self):
        return [instr.max_getter() for instr in self.instruments]


if __name__ == '__main__':
    InstrumentBank()
