Forgot to check Doepfer. It’s great that Dieter is doing something different, and for that I salute him and encourage him.
The CTM64 is not only available now, you can even buy the separate parts and piece them together as needed. It handles up to 64 button inputs.

If you want to make an alternate controller, this looks to be the least costly way. The CTM64 main board is $135 from Analogue Haven. The 8×8 square matrix button board is 125 euros direct, ask Analogue Haven if they have them. You can always create your own. I’m thinking of getting a CTM64 and designing a PC board for a keyboard with a staggered key arrangement, using these tact switches. Caps are available for them—in 6 colors.
Now, if only Dieter would put out that touchplate keyboard he keeps showing……
Actually, someone else will have to come out with it first, so Dieter can rip it off.
Hi. I wouldn’t recommend those switches from Mouser as they require 260g force. For a natural feeling button instrument you want 100 grams force or less.
Thanks for the interesting post. I’m going to share with my friends and look forward to visiting this site again!
That looks pretty sweet.
I wish I had the ability to figure out how to build things like this.
Actually for me this tips is very informative for me ..Thanks for the interesting post i wish i had ability to do it figured..THANK YOU!!:d
Cool idea! Thank you sharing your idea.
Very neat! I never would have guessed that you can make your own MIDI controller!
Sweet! How much would it be to buy one already put together?
Is there a construction manual that I can purchase after buying the parts? This seems like a great project during my school break.
Great idea. What is the most common amount of buttons besides 64? Can I make another controller with 16 buttons instead and have it work the same?
This looks awesome and so much fun to put together! I have always been into putting different electronics together. Thank you for giving me something new to work on!
I was actually looking into the zero. Novation has an eye for making utilitarian products that aren’t to shabby looking either. However, my only hang up with the zero is that it has pads and sliders, which seems great, but when I look at it I just think, if only those pads and sliders were more rows of knobs, I could justify the purchase. Just not enough knobs to fill the shoes of the BCR. I see Livid makes a “Livid Code” which I might look into, however, I’m still definitely down with more suggestions.

I am the same way. I love putting new electronics together. I am always looking for new suggestions and ideas to keep me busy, so keep them coming!

How much are those normally?
