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.

Please clarify: Can voices and performance data on an S-80 be transfered into the CS6R? I like to sell my S80 and get a rackversion of the S80 if the CS6R is compatible. I this possible?

ts and faethontas,

the s30/80 can load all patches from the cs6x/r since the s-series rom is a superset of the cs6x. I did just that on my (now sold unfortunately, regretted it since....) s30. The c6s uses a 16Mb rom (i think) whereas the S uses a 24Mb one (more bread and butter wavs added). The S30/80 only have one plg-slot and don't have and external in or phrase-sampling. Otherwise, they are identical.

Anyone know if the original motif has the sounds of this CS6X synth?

Nice synth. Main strenghts IMO: great synth patches, breath controller input, AD/MIC input for e.g. VH card, additional input for e.g. sampling, decent filters and patch desinging capabilities (waveforms not outdated and with Yamahish clear and crispy edge), separate outputs, good quality built, editor like Motif's that still runs in Win7, space for 2 PLG cards. The only weaknesses IMO: only 128 patches can be stored on SmartMedia in external bank, presence of acoustic instruments for the sake of better marketing I guess. Still inspirational and fun!

This is a mix-cutting monster. The sounds are crazy-powerful, clear-as-a-bell, non-noisy, weird-as-you-could-ever-want delight. At first, I was not a fan of the keyboard, but after performing with it, I realized that it facilitates dynamics and expression for high-speed solos unlike any set of keys I have ever owned.

Filters, filters, filters, filters...there are fantastic possibilities in those filters. I don't know if the more modern Yamaha gear are built the same way or not, but I have never heard them do as well as this.

If you want a unique sound, this is for you!
