The video features features a demo of the CS-80 and its unique sound, along with a look inside the synth, revealing why it’s a monster to maintain.
“In this video, we learn about the grandaddy of them all, the CS-80! It’s an amazing design inside and out. It functions entirely in the analog realm without any software intervention.
I’ll demonstrate the Yamaha CS-80 panel features and then Rob’s exclusive intimate and detailed tour inside the instruments begins. He starts by going inside the CS-80, “Under the Hood”, to explore miles of wiring, the rack of cards, master boards, below the keyboard, velocity, aftertouch, DAC, key code assigner, TSB boards, TKC boards, KAS boards, dedicated effects boar, output board and ring modulator.
Rob teaches us how the unique oscillator boards function, including how they regulate pitch and change waveforms, We’ll also deep dive into the sensors on each key that allow for polyphonic aftertouch. We’ll see the VCF’s and VCA’s and learn about the importance of regulating temperature to keep everything stable. Rob shows us how he matches the uniquely different voices in the CS-80 to make the instrument perform more consistently. We’ll learn why these instruments cost so much to build from scratch and what it takes to keep them thriving today.”
