Yamaha CS6x

The next generation of CS synthesizers is here, with added sampling and features from the AN1x synth! In keeping with the new CS-line trend of analog emulation for dance and electronic music, the CS6x offers real-time and assignable knobs, scene memory and morphing, MIDI controllability and excellent sounds. Yamaha says that this IS the machine for Trance. Its awesome arpeggiators, filters and phrase sampling are proof of this claim.

First the sounds, they're just great! 64 voice polyphony allows for some thick sounds. Excellent (AWM2) Advanced Wave Memory samples provide emulation of classic analog synths is truly possible with the CS6x enhanced abilities. It has a Bit-depth switch which allows you to degrade its output creating 'Vintage' lo-fi quality sounds, which can be cool. And filters... the CS6x has the best one yet with 2,3,4-pole filters with 6,12,24dB slopes and low, hi and band pass filter types (see technical data below for specifics) for just about any imaginable filtration method you can use to shape its sounds.

The CS6x allows you to sample sounds or load in samples using the 4MB Phrase sampler. All the features and functions a pro-quality 16-bit linear sampler should have are found here with sampling at 44.1kHz. Up to 256 Phrase sample clips can be created and used as loops in your performances or sequences. Apply effects to your samples or synth sounds using the vast array of quality digital multi-effects. The built-in arpeggiator is better than any previous CS synths with 128 patterns and filter patterns. The CS6x will also play SMF playback sequences (Format 0) loaded in from a disk. The CS6x is expandable with two slots for Plug-In Expansion Boards which add polyphony, sounds, effects and more! For performance and control the CS6x has a pitch and mod wheel, ribbon controller and 6 assignable knobs. The CS6x also has a built-in 3.3V smart media storage drive. This stores the phrase sample clips, SMF sequences and other synth data on 4, 8, 16 or 32MB cards. Simply the biggest and best CS synth from Yamaha. It has been used by Faithless and Depeche Mode.

"No LFO delay (seriously, even an old Korg DW8000 has that)"

Correction: I realized that there *is* an LFO delay. There is a -common- LFO that can be routed to any and all voices. This one has an LFO delay, ramp and fade...fairly sophisticated. Then there is a -voice- LFO that does not have a delay.

I have to see if the two LFO's are routed to the same item (such as filter cutoff) whether or not the amplitude of the result is summed or if there is priority.

The more I use it = the happier I am. This is a big-boy synth!

Greater that the sum of it's parts, the takeaway should be that the instrument is expressive and it sounds really good. First you love it, then it grows on you! Sampling is useful. Factory patches are not bad. Love, the filters!

Reality check
- Keyboard has a spongy landing
- No LFO delay (seriously, even an old Korg DW8000 has that)
- Bug: The arpeggiator when synced to the midi clock seems to start late. You have to trigger it early (~32nd note) if you want it to be on the beat.

Solid build, a good buy. Really cuts a mix in a warm, old-school way. Still good in 2011

ts you don't need to download any patches.Hust use the factory reset button through the UTILITY MENU and it will load the factory patches instantly.

Does anyone know where I can download the factory presets for this?

underrated, underestimated (lucky for us they are 'cause we can buy them for a bargain) but still one hell of a synth after al these years. Yamaha did it's homework trying to figure out what a synth should look like and sound like is the bottomline with the CS6X. When it comes down to complex soundscapes there is not one other synth around, nope, not even my Fantom and Triton. It's a keeper, don't know why people bother selling this synth. It's build like a tank.Not like your el cheapo plastic tupperware cases they put synths in these days. It' rules period!
