Is it possible to have a linear array of 32 LEDs and receive Midi time code from Ableton LIVE (playing a 32 note clip) to represent the position (note) LIVE is currently playing, so if you have a loop of 32 notes in LIVE the LEDs light in the same loop manner from start to finish and back again and again, is this possible with MIDI Box LC? I search and seach and can't find anything.

Well I kindoff figure everything up with two cores. but is it possible to represent the playing bar position of 32 note clip with 32 leds in a linear array?

Thank you Ultra

To do this I use the drumrack then load lets say the same kick in the 16 slots that the drum rack has, then I draw the clip using a "diferent" Kick-note in a latter style, then i just expand the drum rack and assign midi notes to the 16 mute buttons each kick-note has. Its rather very simple, it can even be done with pots assign to volume.

Hi there every one, It has been a long time with no post, work and loads of work and haven't had a chance to midibox, but again am back Well, I don't really know where to post this but here it goes. I finally found a way to interface live 7 with a hardware controller in a drum step sequencer manner ala Fruityloops to make drum loops. I have done it with a regular midi keyboard and it works but I ran out of keys. I really don't know where to start, this is the design. I will have a 8rows x32columns button matrix (obviously each row represents an instrument[Kick,snare,etc] and each column a step), the first 4x32 sending midi in a channel different than the lower 4x32 I will need the first 128 step buttons to send the 128 notes (on/off) from C-1 to G9 on one channel and the reamining 128 buttons to send the same notes on a different channel. plus i will need some kind of led feed back to show the buttons status, and on the very top a row of 32 leds showing the position that is currently playing, is this possible with midibox? is it possible to keep sending notes in different channels to get enough buttons to complete a 12x32 matrix. or a 8x64? I keep searching for this but all that comes out is the Midibox SEQ 3 Sincerely Rigo Renteria

am doing one of your Dinx4, and yes I changed all nine, I changed the registers and same thing.would it be wrong if, for now, I only use the 3 available inputs and leave D0 permanently grounded, would it cause some problems? am still going to check and recheck but I just want to know I have that option. Thank you so mucho for you help.

rah Honestly .Do you realy think you can make a controller that can compete with m-audio, kenton, behringer, novation, akai etc, etc. Just try to make a decent box , just one box, with all the features of the comercial boxes, usb ports, divers, librarians, lcd screens, all manuals, professional looking panel, screen printing , memory banks, etc. I'll be surprised if you can make it under 100USD only for parts, not to mention labor costs.

Hi there again, well I change the resistor pack for individual resistors, and the problem is still there, but I found something else, if I connect D0 of J6 to ground the notes on/off stop triggering constantly, although the only inputs that work are D4,D3, and D2, because the remaining either dont work at all like D1 or trigger 3 notes on/off at the same time like D5,D6,D7, could it be the 74HC165 then.?

Hi there, thank you for all your help Well this is what I found; I turn the unit without the 74HC165 chip and check the voltages they seem ok (5.3V) but after two minutes the voltage drops giving me the results I described earlier, am desoldering the resistor network and putting individual ones, in a few days I'll repost with the results

After a good inspection with a magnifying glass all tracks and soldering seem ok, I found something strange on Inputs (D7 and D6) of J6 with the multimeter every input reads 5V but D7 reads erratically from 2.4V to 4.4V and D6 reads constantly 2.8V. D7 is the one that is constantly triggering the note on/off, what should I do?

thanks Tim. Well as far as the timing it is constant on-off-on-off but If I turn the unit off for a few minutes (20min) and turnit back on it doesn't start to do that (on-off-on-off) after a minute or two but am checking for those shorts in the circuit, I'l keep you guys informed

I had the same problem and put all resistor networks correctly but now I have a problem with a button that keeps triggering constantly 3479587 1 -- 151 84 127 8 C 6 Note On 3479659 1 -- 151 84 0 8 C 6 Note Off 3479726 1 -- 151 84 127 8 C 6 Note On 3479760 1 -- 151 84 0 8 C 6 Note Off 3479863 1 -- 151 84 127 8 C 6 Note On 3479897 1 -- 151 84 0 8 C 6 Note Off 3479967 1 -- 151 84 127 8 C 6 Note On 3480001 1 -- 151 84 0 8 C 6 Note Off 3480036 1 -- 151 84 127 8 C 6 Note On 3480070 1 -- 151 84 0 8 C 6 Note Off 3480109 1 -- 151 84 127 8 C 6 Note On 3480142 1 -- 151 84 0 8 C 6 Note Off 3480176 1 -- 151 84 127 8 C 6 Note On 3480211 1 -- 151 84 0 8 C 6 Note Off I had a realy hard time desoldering the resitor networks, so am thinking that i might have damaged one or two, I actualy disconnected the button but it just keep going, is this behavior due to something else?

got some pics of the final result , looks rough but at the end it looks good, it is a shame that the camara does not capture an exact image of how they glow.

First of all thank you for all your coments, Here are some pics of the backlit bottons, the board looks rough but at the end it looks good in the front pannel , I did a small change to the box too, I replaced the "giant" toggle switch (which was used to go up and down scenes) for a nice square rocker switch. I still have 20 more to go......hehehe again thank you all :)

I google JB Weld and found this http://www.jbweld.net this is an amazingly strong cold weld, I have seen with my own eyes how one of our mechanics "welded" an overheated cummins engine block, that was basicaly splited in half.
