Cheers JJ, that's cool. I was scanning through all the posts in this thread last night at warp speed & may have misunderstood some old conversations. Just wanted to double check & say hi.

Will keep an eye on the thread. Thanks for replying & merry Xmas.

Hi! Just found this thread, headed over to the website and registered. I'd like to buy two cards when they're available again.

I went on and completely did a thing today and bought a Roland D-50 and stumbled on this thread by chance and also registered my interest in buying a card or two. I really, really hope they are put back in stock as I'm super interested in them.

Another excellent home-brew product - registered for one of the next batch of cards :)

Was just reading about how MRAM works. It is pretty amazing materials technology. Similar in operation to magnetic core memory from early computing days. Very cool!

Hey guys, any news? I’m desperate for one of these and was broke the first time they went on sale. Been signed up to the wait list for ages, but haven’t heard any updates. Just curious how things are progressing (or not)! :)

"or not" is the correct one. Real life is just keeping us busy right now. ;)

Still very keen as this card sounds so good - I have a JD990 and the idea of expanding it's capacity after 25 years is brilliant.

On a related note, I stumbled upon this thread the other day about the risks of a capacitor exploding on SRJV boards. Apparently Roland has issued a warning about the use of these boards. As I have one in a JD990 and some in a 5080 so it looks like some work is needed.

Hey! Thank you for this information as I was not aware of this! I have 28 of these cards in use... I've ordered some replacement capacitors today. I have some work to do!
