well..kinda ( although I did notice the microtonal pitches at times)When you say not tuned to concert pitch, I assume you mean Equal Temperament
what I mean is ...put on the VA oscillator, and the SF2 Osc at the same time. Some samples are not in tune with the VA osc. However my suggestion that with these types of voices, either turn off the VA osc, or modulate the VA osc ( or SF2 osc) to create an effect so it adds to the sound and not go ageinst it.
