Chuck Posted January 28 I don't see much posted online these days about QSI sound. At one time they were THE sound folks for model trains of all scales. I recently seen this posted on another forum by a high end O Gauge importer/ manufacturer. Few years ago I spoke with QSI and they said they were developing a new large scale sound decoder...guess not? "We are out of QSI boards and there are no more to be produced as QSI doesn't have their system chip for sale any longer. So if your QSI system stops working you can easily replace it with an ESU system purchased from us. This took a good amount of planning and design work from both ESU and Robert Lopez."
