FM comparison at signaltonoize.com
I don’t have much to say about this. This comparison only proves that:
1. FM8 is really close to the real thing.
2. The software certainly is cleaner: no dust accumulating or noisy outputs by which you could identify it in such “blind” tests.
3. People will still say hardware is better when comparing individual patches, millisecond by millisecond but will probably get confused when trying to identify which is which from a dense mix.
Even though I’ve stated the above conclusions, I will still buy an original Yamaha FM synth because I care about my CPU and RAM and it will also have sentimental value.
