Taking a reference from some AudioBuffer channels without copying

I’d like to take the firsts channels from an AudioBuffer in another one without copying them, is this possible? or will I do something wrong?

AudioSampleBuffer ab {12, 1024};
AudioSampleBuffer section {ab.getArrayOfWritePointers(), 2, 512, 128};

Or using AudioBuffer::setDataToReferTo() (but I think it’s the same)

Edit: I know the AudioBuffer description states that the number of channel must be the same that its source, but maybe it’s still possible since I’m using only the first ones
