so much more effort but worth it IMO... RGB is too tempting to pass up.

Hang on, you have velocity control with the membrane buttonpads? Or are you just using velocity as the colour 'channel'?Brightness and colour is full programable from OSC and we are making some improvements with midi. At this moment velocity controls colour and it is limited to midi protocol (127 range) and some hardware limitations but...
Trying to upload a photo of my poor first attempt at a controller - when I'm not behind a firewall I'll show you but basically it's a simple 2-channel mixer with 2x2 buttonpads for transport control and a 4x4 buttonpad in the middle for a basic way of navigating session view and controlling drumracks/fx etc.What do you need about 4x4? Explain me a bit please...

Ah a new post on CDM, cue Mudo in 3, 2, 1

Let choose, my friend.

It is possible to have the best of 2 worlds.
In the shield you have two analog input ready (and firmware coded too) but Octinct needs the other analogs... maybe a Arduino Mega will be the answer!hoffman2k wrote:I too got old Sparkfun parts collecting dust here, so its definitely nice to see some new PCB's and OSC control. Are there any spare connections in the kit for adding say 8 endless encoders and have OSC output of the values from the hardware?

It could be possible.
Thanks guys for your feedback and questions!

Cool. I got a Mega. Would it need a different shield or does it fit?Mudo wrote: In the shield you have two analog input ready (and firmware coded too) but Octinct needs the other analogs... maybe a Arduino Mega will be the answer!

Cool project!
You could fit a 4x4 with minor tweaks (take a look at pcb boards... they have the spi integrated making it a bit large) and controled by arduino. Maybe not so easy to implement the rest of the project in the same arduino board (due to unsped shield and rgb chips) but you could implement a hub.

will be moving to a slightly bigger enclosure eventually so it shouldn't matter too much about the size. When you say hub you mean a USB hub with multiple arduinos right?Arduino Mega accept usual shields and I think it could be possible without modifications. At wiki page you have the mail for technical questions (I'm not so pro!hoffman2k wrote:Cool. I got a Mega.

So you have got around the multiple buttonpresses per column limitation? Nice. This was a concern with the SF board alright. My one does have room for diodes btw - they recommend 1N4148, although it hasn't done me much good so far...Mudo wrote:It is not a evolution from sparkfun one sorry.

More or less: Monome project > Arduinome project > Unsped Octinct project > Hangar Octinct revision.
Sparkfun spi boards (almost usb version) doesn't have diodes (they are developed for tetris) and you couldn't press two buttons of the same row at same time.
Different necessities, different board design.
So if I understand correctly you use the Key data to identify the button and the velocity data to send the RGB value, and presumably this would update the board faster than if you update the whole board every time a single button changes colour?Mudo wrote:...We are wondering the possibilty of manage colour in midi mode with velocity bit for output in octinct.rozling wrote: Hang on, you have velocity control with the membrane buttonpads?
