The Mo' phatt contains da most authentic hip hop soundset I've come across, I have the Mo' Phatt board installed inside my Proteus 2000 and it is da Sh!t. I own a Triton rack and can testify that these machines sound very different to one another, as I believe the previous reviewer stated. I tend to use the Triton a lot for lead sounds and drumz, but always find myself padding out the my beats wid Mo' Phatt sounds, I produce mostly Hip Hop, but also get thru a considerable amount of garage and R&B tracks, and the Phatt is just....Phatt! It's definitely not as buff, in the sound department as the Triton, which can easily dominate tracks if your not careful, or as well endowed with Fx, but you get Emu synth architecture, which IMHO is da best amongst the non-va synths, and dat sound, which is bang-on 4 Hip Hop music.
I'd have to disagree with the last reviewers comment about the MPC thing over the Triton, 2 many people get caught up in the near-legendary status of the MPC, but to me it's a pretty average sampler which wouldn't sell that many units in the 21st Century if it wasn't for the hype, its sequencer and keypads, its a great machine don't get me wrong, but you pay for more than just the technology when you hand over money for an MPC, your buying into a bit of history! For £900 you get a new (limited edition) MPC the in the UK, for £1050 you get a Triton Rack Get a sampler sure but if you already have a sequencer get something a bit more modern and feature-laden than a MPC.
Back to the Mo' Phatt, every hip hop producer needs a module or two, somtimes samplers and turntables are just not enough and for Hip Hop producers especially, the Phatt is a near essential purchase, it's just got some great sounds in it and a sweet set of drum kits, loving it! loving it! lovinig it!
