Improved DM41X keyboard

Post by grsbanks » Tue Sep 22, 2020 11:16 am

A lot of work has gone into improving the keyboard on production units of the DM41X as this was the Achilles' Heel of these machines.

The new generation of keyboards has been completely reworked. The keys have been redesigned to press on the domes differently and the domes themselves are of a new design.

This brief video shows how responsive the keyboard is now: https://youtu.be/OaKvP8-2iB0

Great news! Will there be an upgrade kit for the beta units? Or should we plan on buying a production unit?

We're looking at what we can do for an upgrade kit. Several ideas are being tossed around at the moment and we need to narrow it down to one or maybe two options that make economical sense for everyone and that don't require too much technical skill.

From a collectors point of view buying a second one makes more sense.

Will this design affect the DM42 as well, i.e. will also the DM42 be allowed to profit from it?

I appreciate it. Is there anything like a schedule?

I had a new DM42 shipped to me on September 16. My fingers are crossed hoping that it has the new keyboard.

What a wonderful news!

The video convinced me to buy a production unit and if upon testing it, the unit really works, then more units will find a new home.

If you changed the domes and the keyboard to get that kind of results, I do not see what types of upgrades you are looking for DM41X beta and for DM42 without changing both. If you offer DIY kit for the technical skilled and send the unit back to SM for the other users, you cover both side of the spectrum and you make everybody happy. If made available, I will upgrade my DM42 (1st gen unit with a vey high % of missed keys) and my DM41X beta unit.

PS: is it possible to buy a DM16L LCD part ?
One of my unit was bleeding badly, I somewhat corrected it with heat, but still there is some bleeding left that would love to get rid of.
Thanks!
