I just posted LEET Control8 documentation with all files needed to build your own:
I just published Control8 (the 4 by 2 version above).
It became really good with the custom knobs and miniature trimpots:
Hi
CV out might be tricky, depending on your needs. The Arduino can only provide 0-5V so anything above that requires some sort of amplification and external power or DC/DC conversion. It can definitely be done, but for eight channels it becomes rather complex. For high quality signals external D/As are preferred, but for basic needs PWM would work with some filtering. The good thing with PWM is that you can amplify the voltage using a single transistor before the filtering, the bad thing is that modulation frequency (500Hz) harmonics will pollute the CV, affect response time, limited resolution (8bit) and possibly linearity…
Hi
The devices are sending MIDI over USB, so you need a USB host that communicates with the devices, power them and generates the sound. The host can be a PC, Synth or Mobile phone. To connect several devices simply use a USB hub. There are great programs free of charge you can try, like sunvox.
I hope I didn’t misunderstood the question.
Hi
Instead of using a slider I thought it would be cool with a miniature lever. Check out these images:
It should be quite easy to integrate in any design…
Its great to see that it is getting attention. I hope it will inspire more people to learn both electronics and music – the more people that sees it, the better!
Here are other great sites that have covered the project:
/j
I have made a first version of a raspberry pi based sound engine. The OLED and keys are working and I found a python-based menu system that allows navigation, configuration and execution of various commands.
I think it would work great with software synthesizers as:
· ZynAddSubFX
· Sunvox
· Fluidsynth
· Samplerbox
· etc
The UI can either use 4 or 6 keys for navigation and there are 4 or 6 keys left for selection of presents.
If anyone wants to help with development and integration, let me know.
Hi
For some reason your replies got caught as spam (sry for that).Do you know how the LEDs are controlled in the vmix? Are they set by MIDI signals, or coded so the last one on each row is on?
How many buttons do you want? I have sketched on a larger pad with 14 LEDs and switches… The LED rows are grouped, but it should not be too hard to swap a LED and button row.
The sliders are quite bulky, I have some ideas for 3D printing a smaller slider using the same trimpot…
Hi
Another user noticed that the pad code was actually control code by mistake (now corrected)
Ensure you are not using the wrong version.Sorry for any trouble!
Hi
That’s a great idea! (and probably not too difficult)
So, you mean 1 row with 4 LEDS and then 3 rows with 4 push buttons each below (and keep the tree buttons on the right)?
Will the LEDs be used by the broadcasting software?/j
I like the semi translucent material and think it will look great (once the LEDs are working.)
It is quite easy to test the connections with a contingency tester (voltmeter) and measure between micro-controller and the three connections on the right at the lower led strip. (assuming that the right firmware is uploaded).
Good luck!
Hi
I plan to redesign control in the near future and will probaly use trimpots instead. There are pros and cons: They are not as robust and the feeling and accuracy is slightly off, but size, ease to integrate and cost speaks to their advantage. Maybe avaliability too.
