Product Information This is the synth your grandma wish she had! Introducing the Behringer MODEL 15! This compact analog synthesizer features dual VCOs so you can create super-fat bass lines and awesome lead sounds that’ll have everyone in the crowd vibing! Features The Behringer MODEL 15’s semi-modular design makes it ready to go right out of the box with its 48 patch points at your disposal so you can connect and integrate any module in your collection. And if you were a fan of the legendary System 55, we’ve taken everything great about that and put it in a sleek, compact chassis, so you won’t need a whole truck to transport your setup! Featuring a pure analog signal path, the MODEL 15 features dual oscillators each with 4 waveforms, pulse width modulation and sub-oscillator. On top of that, the MODEL 15 also comes with 3 separate memory slots for its 256-step arpeggiator with multiple playback modes.
