Hey,
I’m searching on Mouser but I can’t find the reference of a “touch slider”, something similar to the ones found on DSI synth or Push 2. Do you think this is something that is custom made or do you know the reference of the part ? I’m not sure this is the correct term, maybe it’s called capacitative surface or something…
I was thinking I could use one on a module belonging to the Teletype ecosystem (8hp, 8 buttons and a touch fader + Teensy)
I’m not sure it’s the same technology but you could achieve this with a membrane potentiometer like this:
@caelmore is right about them being called ribbon controllers but I’ve never seen this term used outside of synths so it’s not much use when looking for for parts (or hasn’t been for me anyway).
Thanks @caelmore and @oot I will search in this direction. These ribbon sensors from Adafruit are really interesting. I could also try to open the DSI pro 2 and see if it uses something similar or if it uses a series of small capacitative sensors but the sliders on this synth are also pressure sensitive, so it might be something a bit more complex, but I like the idea of a ribbon controller. Now that I think of it, the Tetrapad uses a similar tech as DSI. But for the sake of simplicity, the Adafruit sensors could be just fine for a small module I guess.
More generally, I wish I knew what kind of parts/sensors are used in MPE devices like Roli, Linnstrument, KMI, most probably very custom parts etc but that’s another story haha
Ah, yes ! Thanks @okyeron this seems to be the kind of « smart fabric » used for MPE devices. That’s an option I should investigate. This combined with the ribbon controllers mentioned earlier. Really interesting. Now that you mention the term FSR, it reminds me of the FSR 1U made by Intellijel. This part is also used on the Tapographic Delay made by 4ms. I’ll try to source the part
The FSR matrix that @okyeron posted is very fancy (yes, smart fabric and can be used for MPE) but FSRs like the one in the intellijel module are very simple and inexpensive.
The “slider” is, yes a ribbon controller, aka linear soft potentiometer, and also is an example of an FSR.
