The Bird Spirits can be defined as a dual voltage controlled low frequency oscillator and multiblender. It can do a lot of things, the possibilities are a lot, it can be used as a voltage modulator (that is the principal function), it can be used as a voltage blender, it can create complex signals for modulation, it can be a different sound generator using the high frequency ranges, it can generate ultra high frequency signals for modulating audible signals, it can be used as a led vu meter using the blenders. These are some typical applications that can work for you.
