I think you can replace the spring in the buttons with one that is harder to press?
Unfortunately, I donât know which keys to order. Do you know which ones would be adequate, harder?
Hi @sebastian,
I havenât had any issues of sort so far, with the feedback accuracy of the keys, on my two keypad models (12 keys + 4 encoders and 15 keys + 3 encoders).
They click sound and reliably, with the appropriate degree of physical resistance. Sure, their aptic response is quite different from that of the excellent V5 rubber pad, especially with bold/long presses, but imho the two solutions simply represent distinct flavours of equally functional keyboard actions.
Best regards ![]()
Iâm sorry but i have very little exact knowledge and often find myself confused when scrolling through the endless possibilities an aliexpress. But i think you can try and msg the seller and ask? Or take apart one key cap and have look at the clicker underneath.
But also as Aethermind says; There are different flavours. But also habits plays a role. Iâve learned that quite as often i find tools or ideas difficult to internalize just because they are unfamiliar to me.
I can only comment on the two models I own, but, assuming that two samples of a given object are enough for a statistically consistent analysis (which obviously arenât), the keys on my keypads feel exactly the same.
Regards

Well, now it is time to present my visually pleasing (at least so I think) latest Zynthian contraption (I do not dare qualifying it with the blazoned title Success Case). It was essentially meant to recycle a spare Pi4, leftover from the V5 > V 5.1 update.
I ordered from AliExpress an apparently apt Unew 8â touch display with Raspi case. Long story short: the manifacturing of the innards, advertised as capable of holding safely and conveniently the computer board, was manifestly poor, with PSU and micro-HDMI adapters extremely prone to rupture. Moreover, the built-in active cooler was unbearably noisy. Thus, I ended up enclosing the Pi4 in a lovely machined grey aluminium KKSB case from Amazon.
The touchscreen was available from the factory only in a boring plain black ABS finish, which I unreservedly disliked straight away. After some deep research, I discovered that the English brand Army Painter provides an extensive palette of spray colours with embedded primer, for model-making and fantasy figurines in plastic, of which I rather predictably chose a beautiful Hydra Turquoise.
The audio compartment was implemented with a surprisingly well-sounding Sabrent USB-A micro interface (just mini-TRS stereo in and out, but enough for the purpose), and the Midi feed was done with a Y USB-C cable (data+power), through which my laptop recognised the Zynth as an available Midi out from Cubase, once I did the trick of sending MIDI data from a powered USB-C hub.
For the tactile interface, I got another model of the sturdy Romoral store keypads with potentiometers, from AliExpress: in this case a 15 keys + 3 pots variant. All the UX configuration was made through key-binding in webconf, and obviously I used on the UI one of my custom Zynthian colour profiles.
I cannot enjoy on this build the powerful and Pi-5 restricted DSP 56300 releases (which I adore, as many of you know), since at the core of this mini-system there is a Raspi4 with 8 GB and ordinary mSD storage.
Still, all in all it fares very well: the good, proven and time-honored Z plugins are there, it sounds clear and crisp despite the humble audio equipment, and the thermal dissipation through the full-metal enclosure is excellent.
It does look stunning Aethermind what you have built here, even if it âonlyâ runs the rPI4
Love the bluish colour of the casing which looks very nice. Also, i guess any heat-dissipation issues that you theoretically might have would be non-existent. The separate keypad is genious. In my mind, that is the ultimate controller. Great work ![]()
OK! butâŚâŚ..
@wyleu docetâŚ.. ![]()
Canât a wyleu take a long relaxing bath without being disturbed. . . . ?
Those poor ghiashaâs have traveled a very long way . .
yep , definitely requires attentionâŚ.
Agreed! ![]()
.. Does the backbone of a building rest? Then @wyleu canât restâŚ![]()
That looks amazing.
Well i got the two Romoral keypads (link) - the ones with 12 keys and no BT or LED.
By removing som material from the base of the upper keypad and the rubber around the USB C plug i could fit them together like this:
Nect step: Route cavity for both keypads in a piece of plywood, outsource a âcable-spiralâ and spiral the two cables inside. The longer must be dubled back a little inside the spiral so both USB A plugs are equidistant from the keypads. Off course i would maybe have preferred to do something like Toffâs done earlier in this thread, but i have plenty of USB ports i think.
Here is an article on Reddit
Iâm buying brown switches here
Iâll let you know how it works when i get them!
I do not think Bluetooth keyboards are working with Zynthian? If they do iâd sure wish i had bought the BT Romoral keypads instead ![]()
Hi, @core.east since I love drawing with Fusion 360 (Iâm not an expert, but Iâll try), if you send me the exact measurements (But also the overall size in your case) or a link where I can see them, I could try to design a tray-like container to hold the two units together so that moving them doesnât break the connector⌠if I can, Iâll post the print file here so anyone with a 3D printer can test it.
I donât know if you can post any filetype in this discourse forum. You can certainly post a link to github or google drive or whatever vendor you like.
I have already uploaded .stl files of my Black Pearl case without any problems, also because they are only a few Kb.
