The included synths Spector and Mystic do not behave consistently. If you load two instances of either unit and pick a random preset on one and then manually copy all the parameters onto the other, the presets will not sound the same.
I’m running Cubase 6 64 bit on Snow Leopard.
Prologue lost its LFO MIDI sync function with the jump to 64-bit so I’m thinking something crucial was disabled in both of these other synthesizers. Or maybe they’ve always been broken, I’ve never used a previous version of Cubase.
The way I see it, without consistent behavior of the synth, you can’t learn the subtlety of the engine. Makes it more of a preset machine.
