and yes everything worked when I tested with a pot.
i think it’s my ribbon build itself.
i check again and when i force at the end of the end with the tip of my nail it goes up to almost 2V, and the velostat continues still under the board, like this
the rest of the volt is hiding under the board I think .
I’m going to have to rethink that physically.
Even if I get the correct voltage it does not solve the problem that there is zero V on more than half of the ribbon and that it only starts to increase towards the very end.
To give some news, now everything is working fine !!!
(gate out, CV …)
I reworked my ribbon, redone the tests and measurements with the Serial Monitor, tried some change of values in other parameters of the ribbon in the code and adjusted according to the results, until something that suits me.
Thanks again to @eric@sebastian and @analogoutput for your help
(damn arduino but i learned again some new things about it)
From the start I have been thinking of adding a rail system to have a mechanical “hold” function, maybe with a little wheel …
I almost finished everything, soon the tests, pictures …
Excellent! How much Velostat did you buy and for how much? Hopefully I don’t need any; at one point I thought my SoftPot was messed up but then later it seemed to be okay. I’m still trying to decide what to do with the interface, I could put it back together as it was (in its own box with USB power) or put it behind a module panel or rebuild it better. I’m thinking of adding range and offset pots. In any case I’ll probably ditch the existing code, I’ve got a start on something cleaner.
After testing in a real world with modules, the ribbon make some jump note when I release the pressure between the note i touch, i must also go to try to entend the course of the ribbon (testing some new values in the code)
Some change on the way, like 2 rails for the wheel / 1 rail at the end with a counterweight system , test Gate attenuator pot / CV attenuator pot finaly (more usual),
it took longer than I thought, especially with the code problems (thanks again to you) but I succeeded and am very happy with it
it’s a really very cheap solution with velostat even if it’s not perfect like the Sofspot.
This is a video track of a jam with the Ribbon Controller patched into a Quantizer
This is great, thanks. I might have to give this project a go again. The finished product looks a bit like a guitar - I’m tempted to do something like this with buttons on the box as ‘strings’. Added to the growing wishlist
I rebuilt my ribbon controller interface (using the “lite” version of my dac/ino board) and wrote new software for it.
I’m happier about the interface hardware, since the old one was the first electronics I’d built in several years and was a rather messy protoboard thing, and I’m a lot happier about the software, which is very much simpler and better organized than the code I’d been using.
