Mapping LED's using MATH!

[at0m active]

Hey everyone, I just signed up to the forum and read a few of the stickies but I'm in need of some help.

I'm trying to map the LCD output on my NDX-800 to the loop size for the deck. I'm using two CC's on the LCD to display the loop size.

For loop sizes 1, 2, 4, 8, 16, 32: CC71 will display accordingly.

For loop sizes below 1: CC71 will display 1
CC72 will display the denominator (2, 4, 8, 16, 32)

[CC71] - Whole Numbers
[CC72] - Fractional Denominators

At the moment, I'm working on trying to get the denominators to display correctly.

..well before I could finish posting this, I seemed to have figured it out. I had to create a slight overlap for displaying the values otherwise it would send the right value, then overwrite it with a 0. There might be a cleaner way to do this but I'm pretty pleased with how it works.

1/32 loop size
CR: 0 to 0
MR: 16 to 32
inverted + blend

1/16 loop size
CR: 1 to 1
MR: 8 to 16
inverted + blend

1/8 loop size
CR: 2 to 2
MR: 4 to 8
inverted + blend

loop size 1/4
CR: 3 to 3
MR: 2 to 4
inverted + blend

loop size 1/2
CR: 4 to 4
MR: 1 to 2
inverted + blend

loop size 1
CR: 5 to 5
MR: 1 to 2
blend

loop size 2
CR: 6 to 6
MR: 2 to 4
blend

loop size 4
CR: 7 to 7
MR: 4 to 8
blend

loop size 8
CR: 8 to 8
MR: 8 to 16
blend

loop size 16 + loop size 32
CR: 9 to 10
MR: 1

Second that!

I am about to try this on my Traktor Kontrol F1 and I have a few questions.
1) How did you get the LED display to have two CC's
2) is each cluster of commands you have there a new midi command with all the settings?

thanks a lot! if i can figure this out you may save my sanity yet

The ndx-800 has a midi-programmable LCD display. I just printed out the sheet from numark and messed around for SO LONG until i understood how it worked and then got it to work the way I want it to. If your f1 doesn't have an LCD that lets you program it with 2 cc's then you're pretty much out of luck.

I can't seem to find the MIDI send/receive sheet for the ndx800 but it would help you understand what I mean. The LCD is broken into programmable sections which is what allows the customization. I'm not sure if the f1 is AS customizable..
