madmom does not have such a sophisticated process management, so you need to do this by yourself, i.e. wrap the beat tempo sub-pipelines in a parallel processor and use in_processor to feed it.
in_processor = madmom.features.beats.RNNBeatProcessor(**kwargs)
beat_tracker = madmom.features.beats.DBNBeatTrackingProcessor(**kwargs)
beat_processor = madmom.processors.IOProcessor(beat_tracker, beat_callback)
tempo_estimator = madmom.features.tempo.TempoEstimationProcessor(**kwargs)
tempo_processor = madmom.processors.IOProcessor(tempo_estimator, tempo_callback)
parallel_processor = madmom.processors.ParallelProcessor([beat_processor, tempo_processor], num_threads=2)
pipeline = madmom.processors.SequentialProcessor(in_processor, parallel_processor)
madmom.processors.process_online(pipeline, **kwargs)
However, you have to make sure the your beat_callback and tempo_callback accept two arguments (data, output).
HTH,
