The Yamaha MX series is a new workstation that is really popular. It can provide you all of the latest synth sounds, excellent pianos, organs, electric pianos, orchestral instruments, and even retro 70's, 80's and 90's tones from gear such as the DX7, CS80, and SY22.
It has hundreds of waveforms to choose from, including different instruments and synth waveforms. You can even do wave sequences much in the vein of the Yamaha SY series, Prophet VS, Wavestation, and PPG and Waldorf Wave.
There are 1,000 and counting sounds from the Motif XS and XF. There is velocity on all models, aftertouch on the 61-key model, and weighted key action on the 88-key model. The imitations of instruments are great, except for the solo strings, which have a vibrato that limits their playability. There is an LCD screen, which shows the presets that are being used.
It is 16 part multitimbral, which allows for some great layering and split zones. There are hundreds of effects, including reverb, delay, chorus, distortion, wah wah, tremolo, and more. The standard pitch bend and modulation wheel are on the side, which makes it more expressive.
It has been used by several artists.
