Maybe you don’t know this but in Reason you can use the Soft Clip effect without using the Limiter of the MClass Maximizer. Just switch off the Limiter button and the whole device now works as a soft clipping device. You can overdrive the signal but the device will never ever go over 0 dB. The Soft Clip Amount parameter goes from sharper sounding clipping types (more high overtones) to a very rounded sounding clipped tone (less high overtones).
Don’t use it on the master, although you perfectly can, but use this per channel. You can fool any Summing Bus Purist with it 😀
