It seems like you are not capable/having enough resources to fund a continuous development of the firmware. I say this based on many of the types of problems many people are having according to my experience (as a software developer) should be quick fixes but nothing have been announced or happened here in any way signaling that anything at all is happening. I understand that a product development process can benefit from sparse communication but there is also some kind of limit after which it starts to hurt the product as well.
I think you should follow what Roger Linn is doing with the Linnstrument and open source your firmware to get help fixing and adding things.
Just wanted to put this out here, its sad that such a great product is so limited by not evolving as it has the potential for.
