The Mellotron Group

Since I'm new and not up to speed with the group, I'd like to know if anyone knows what Marcus Reisch is doing with the digital mellotron.  I recently purchased one and it works great, but there seems to be no activity with his website as I wanted to purchase an additional sound card with 100 sounds.  I emailed him over 6 months ago and he said that the card would be available in a couple of months.  Since then, nothing has changed on his website and I was wondering what is going on.
