Firebox controller for ableton

41 posts in this topic

Did you modify it for the correct number of AINs?

AUAIMBCTG?

well i grounded everything yes.

i also tried without using any AIN modules (just directly hooking up the pot to the Core and the pin value still changes when the pot is moved.

here is a dump of the output when moving the pot in UNMUXED mode

00000000685040 ms | [b0 28 4A] Channel 1: CC LSB 8 (Balance) value: 74

00000000685052 ms | [b0 18 4A] Channel 1: CC Undefined value: 74

00000000685189 ms | [b0 38 4A] Channel 1: CC LSB 24 (Undefined) value: 74

00000000748217 ms | [b0 20 49] Channel 1: CC LSB 0 (Bank Select) value: 73

id like the midi output to be as follows:

B0 28 4A

B0 28 4B

B0 28 4C

I'm kinda puzzled here... It definitely should not do that. Can you show me a photo/video of the core with the one pot connected, all other AINs grounded?

Sweet, thx man. Maybe you could also upload your firmware's source? this should be the same one you ran "make" on, to build your hex file; in fact to be sure if you could do that again before you upload it that would be great.

aaaand the pics....

pic #1 is the connection of the pot to the Core, each unused pin is grounded on the breadboard. Red = Vd, Blue = Vs

pic #2 is the grounding of J5(B) i believe (ain2 of the core)

pic #3 im sure you know what that is.

Try setting the number of pots in the .h file, grounding the pins closer to the pic, and losing the breadboard if you can.... It's midnight so I'll look again tomorrow when my brain is on :)

You've got the space in your design - why not go with a 40x2? More is better when it comes to visual feedback.

hey guys,

havent been here in a long time. been busy rennovating my house.

anyways im back to work on my controller. i've decided to keep things simple, and the reason being is because a friend of my gf owns about 40K in machine shop equipment so i am able to finally experiment with my front panel. i decided i am going to make things simple, use the mixer briefly for a few gigs, and see what is missing before i add more buttons, lights, etc.

here is the panel cut. this weekend i wll be cutting the holes for the knobs.

if u cant see the image visit my blog www.jamiea.ca

FYI, the front panel is made from aluminum. I picked up a piece of aluminum maybe 60" x 25" at a local metal shop for about $20 CDN. So essentiall i can build two front panels from the piece of aluminum i purchased! yippee!
