The Moog Mother is Semi-Modular Analog Synthesizer. From Sweetwater Sound:

"This distinctly vintage-voiced, raw, powerful synthesizer boasts switchable lowpass and highpass Moog ladder filters (20Hz-20kHz), a voltage-controlled 32-step sequencer for self-contained programming, a MIDI input for external control and MIDI to CV conversion, and a 32-point 3.5mm patch bay for interconnectivity and extended synthesis capabilities."
