This is a statement I read often. However, with all due respect, I can't help but feel that those who make this statement have not taken the time to investigate all of Massive's wavetables in conjunction with the spectrum, /bend+, bend-, etc., filter types, OSC Mods, etc.
See
Exhibit A. This gent has taken the time to create animated oscilloscope captures of every single massive wavetable along with their variants when sweeping the WT-Position pot. As you can plainly see, there are a shit ton of variations here. When used in combination with varying modes, filters, and modulations there is seemingly an infinite number of sonic possibilities that can be utilized.
Again, I'm not trying to patronize or bust balls. Rather, I want to make a point that while Massive (or any other popular soft synth) may seem like a one-trick pony, it's only limits are truly those placed on it by the user.
Cheers.
