What are the main DSP changes/
improvements of the new MPs
compared to the previous generation?
Well, the new chip we’re using in the MP11SE/MP7SE is several times more powerful than that found in the MP10/MP6, so some of the inconvenient restrictions (e.g. the PIANO and SUB sections would previously share the same effect type) are no longer an issue.
The greater power also allows the reverb, effects, amp simulator, and Virtual Technician resonances to be far more complex and detailed than before. While there had been gradual improvements to the MP’s effects, the system was too… ‘standard’ – for example, you had Chorus1 or Chorus2, and a few parameters, but that was all. This system is probably fine for home-oriented pianos, but professional players require fine-grained control…various different types of Chorus with distinct characteristics, and many parameters to adjust.
Reverb is greatly improved on the new MPs, too. The older reverb used on previous MPs hadn’t really changed for several generations. There were different reverb types, but apart from depth, their actually character didn’t change so much. The new reverbs are all distinctive, and recreate their intended environment much more realistically.
The faster chip is also useful for creating more accurate models, which are used for Virtual Technician resonance effects and the new amp/speaker simulations. As a guitarist, I’m obviously interested in pedal effects and different amps, so it was good fun remaking the new amp simulations. I spent quite a while visiting music studios, testing different amps, and analysing how they affected the sound character using my equipment. I would then return to my office and use these recordings for reference while writing the new amp sim modules.
