Yamaha • CS-5

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.

There's a lot you can do with this little thing, especially with the trigger and CV. Really fat, really wide filter.
The only downside.
When playing up, the monophonic is fine, but playing down the scale the lower notes wont pick up until you release the higher key. Which can be a negative if your into mono solos. Other than that, it rips!

apparently some guy bought one on a vemia auction and found the album insert for aphex twin's "selected ambient works v II" scrawled on the back of it
