Summary: I added the MM6 to my home studio specifically to get the Motif voices, and found there is more to like about the little MiniMo. It is trivial to customize any voice at all, to truly make them 'your own'. I use it extensively in my own compositions, and recommend it if you don't already have a Motif.
Pros: Easy to Use, Motif Voices, Pre-programmed music, Realistic Sound, Responsive / Good Action, Simple Interface
Excerpt: The Yamaha MM6 is Yamaha's 'baby' version of the company's flagship keyboard, the Motif. The MM6 offers a wide variety of sounds, most of which are strictly taken from the Motif. It also has a wide variety of ways of creating new sounds and editing them. There are many DSP effects to choose from in the Edit and Utility menus. It comes with four classic knobs with controls such as Cutoff, Reso, Attack, Release.
Excerpt: The MM6 is one of the more affordable synths from Yamaha, it does have some of the Motif Sounds but not all of them. The sequencer that the MM6 has could be a lot better, it is not easy to use and not very good. You can control your sound easily with the MM6 and add effects and tweak sounds quickly and all in real time. The MM6 has a arpeggiator on it and some built in groove sounds for all your background accompaniment.
Excerpt: The MM6 is a keyboard that after messing with it for 5 minutes it will feel like a toy. Its not well built and the keys are plastic and have no weight to them. The whole board overall feels like a 50 dollar off brand midi keyboard. But that doesn’t mean that its not a good quality as far as functions and sounds because it is, just the way its built was a big disappointment to me.
Summary: It didn`t take long for me to get to the problem of the MM6. Quite simply it is described as a workstation, this is not true. If you are expecting to create a virtually finished piece from this machine then you will be disappointed. There are severe limitations to what this keyboard can do and it felt like technology had stood still. It felt like a `home keyboard` in the yamaha PSR range and not the semi professional synth workstation I was expecting.
