To me over all this rates a solid 8. It's not a great synthesizer but it's a little over mediocre. It would be pretty much strictly just for presets because there are few parameters to change anyways. The few changes you can make can only affect the preset choose from the many available. 3rd party expansions are available of which I only license Mo'Phatt which is inredible and extremely useful for stand up DJ and hip-hop. From that west to east coast and probably north and south too. I'm sure you can find mo'phat expansion useful for drums and all cool sounds for stand up DJ. The only thing you would need to accomplish that.
To me because the Dimension Pro is only valuable for drums on Mo'phatt expansion. The built in presets on Dimension Pro are not valuable because they aren't of the absolute highest caliber. But they are quite well suited for decent orchestra and decent EDM but with out very many choices in the EDM. The violins are noticeably good and realistic. The reverb can be turned off also. The violins can be use for many uses including hip-hop. Mess with the attack to get that quick sound. It varies but can be done after hard work. Also there are many violins to choose from. Including 1st 2nd 3rd 4rth and maybe 5th I believe. This to me is not biased because I like violins. They just seems much more noticeably better and usably because they are simply better sounding.
Its simple and easy to use for a child. For me all I want out of it is to use my mo'phatt hip hop and DJ drums. They're excellent and top notch and indispensable for hip hop. Again, the reverb can be taked out 99 precent from mo'phatt too. There's a reverb and efx button on the synth. Have at it it's a blast with all the many many MANY sounds on mo'phatt expansion.
PS. NO freezes on my PC. A little difficult to install sometimes if you aren't good with that.
