The CS-5 may be a lower-end CS series synthesizer from Yamaha but it still has all you need for vintage analog bass and synth effects at a very affordable price! The CS-5 is a single-oscillator monophonic analog synthesizer with classic filter, envelope and modulation controls. It features 37 full-sized keys, a multi-mode 12 dB/Oct resonant filter, an LFO with sample and hold, and an external audio input you can route through the VCF or VCA sections. The CS-5 is a very flexible and modulate-able analog synth that is quite capable of warm analog bass and bubbly synth effects! The absence of patch storage, MIDI and velocity are just reminders that the CS-5 is old - it's Vintage! It's been used by Siouxsie and the Banshees, Depeche Mode, Richard Barbieri and the Sneaker Pimps.
