Oeps, crossed the line between newbie and idiot i think :P Even for a non programmer with the documentation in the code changing led color behavior looks dead easy . Great stuff TK and thanks a lot for you help. Now just wait for the stuff to arrive to start hacking away.....

Cooooool. Thanks man great stuff. So if I forget about layer/bank switching for the moment loooking at the led feedback problems and use your software and build this baby using a 3 pin duo colored led instead of your 2 leds, I should be able to show next to on/of state a flashing color at each cycle for my ableton clips. (since it sends out vel 0 for stop , vel 1 at each cycle and 127 for on as found in other trhread) . IS this correct or am I missing something ? I am pretty ok in soldering , just the programmin stuff is not my thing ;D Btw if I use normal momentary buttons do I need to bether about this debouncing stuff (no idea what it is but is only mentioned with these funny rubber keyboard buttons. EDIT: Duhhhhhhh , after looking better at your pics you are using 3 pin leds. :-X Is it easy to modify so note on (vel 127) is red (instead of both leds=orange) ??

Shit you are right. Did not think of that, would only work with looping clips you have to start/stop manualy. Hmmmmmm :'( :'( :'( Looks like I do have to build the 8x16 monster then ........ Or maybe go for a 16x5 or 16x6. With the Monodeck Robert has written a MAX patch that according to his website send clip status to the leds. That would be one way probably. I wonder how the Monome guys do it then??

Yes that was what I figured. Thats why I described in my first post that before switching, the leds status needs to be saved.\ and after switching restored from the active bank/layer. Assuming you start with all clips off and only using the buttons and not the screen to trigger clips , the leds should remain accurate. Probably easier to just make a 16x8 matrix instead , but I prefer a smaller sollution if at all possible. I saw this bank stick thingy but could only find references to it saving pots status. Does it also save led status ? And is the switching fast enough or does it take vary long to save a bank.

Wow suddenly so many replies, Thanks guys , so much info. This forum rocks. To explain what i want to do in Ableton is simple. 8x8 button led matrix should be able to fire 8 clips/slots per track (1 active per trackof course) and the leds just indicate if the clip is active or not (as far as I understood ableton can easily send back the midi message to do this. This far I understood from all the reading). But my songs generaly have more then just 8 tracks so I want to flick a switch , hit a button or clap my hands (whatever works) and then instead of firing clips into tracks 1-8 I fire clips in track 9-16 (and the leds should show the running clip status of the tracks 9-16 otherwise it is useless :P ) . Thats it , so just 2 banks/layers whatever, triggered by one or if needed 2 switches. Feels simple. I called this (ignorant as i am ) layering, but could be called bank switching etc etc. It is completely irrelevant what midi message (eg CC or 64 different note on/off) the buttons send since i can map any message to any slot in ableton. Just when I switch banks/layers all 64 buttons should of course send other messages otherwise (edit: or on a different channel the same message) they still fire the same clips and the leds should show the running clip status of the tracks 9-16 otherwise it is useless :P I was inspired to go look for home made controlles by te Monodeck (pure porn !!!!). Also saw the monome, which looks exactly what 1 want (although reading the replies here the thing can do much more than my initial goal but a monome clone would be a plus ;D ;D Thanks TK I will have a look at your (and others) examples, but hope you understand what i need now. Must be very simple and straightforward for you gurus here. Edit : TK after looking at the pics this is exactly what i need (albeit in a 8x8 instead of 4x16 config). WOW. Do you have any ready made aplpication i can just load in and go with it ??? How about a connection / wiring diagram since it looks very different then the standard Midibox wiring. Very cool how you build your leds on the buttons so you have clickable leds.

Hmmm after reading about the button matrix I get even more confused because there I lose some Douts , which I need for my 64 leds and also seem to need other software again. Help I am getting lost snik snik. My goal is not to save dins or douts (i will get more if i need them.) I just want to know how exactly to approach the configuration of a 8x8 button with 8x8 led feedback matrix (which is standard midibox64 mios so far is clear by me) plus allow for some sort of layer or bank switching while maintaining active led status saving/reloading as described earlier. Whatever is easier to do without extra programming (with of the shelf applications). Or, worst case, if it requires extra programming some code since i know absolutely nothing of C-programming. :'(

Aha, ok that takes care of the switch and led feedback parts. But still the layer switching is not clear to me. If I just install the midibox64 mios can I then somehow configure it to use layers or do i need to do more (and if so what exacly, I am a complete newbie in this midibox stuff)

Thanks for the feedback, but I definately need the leds for feedback of active playing clips in Ableton. Thats what I use the buttons for. So as far as I understood i need 2xDIN4x and 2xDOUT4x for 64 buttons. When I switch layer or banks wharever the best sollution is all leds need to be restored to there active/non-active state letting me exactly know whta is playing and what not. Assuming I do not mind giving up some buttons , how would I approach this layer switching then in this case ?

Hi Midibox guru's. Just found this board a week ago and have been sucking it dry for info about this great project(s). Have already ordered some stuff to start building my simple midibox64 8x8 switch 8x8 led matrix (no display pots etc just clean button/led box) to fire away clips at ableton live. (dont need pots etc since have several other controllers to do that stuff). My question is : Is it possible somehow with the midibox64 to have some sort of 2 layer concept with lets say 1 button + 1 led , which when pressed once shifts all buttons and leds into another layer where the leds display the actual button status of that layer. Pressed again switch back to first layer. (i may need to give up 1 button / led from my matrix as i understood you can only adress 64 of them with 1 core but that is less important). Or an on/off button for that matter. Is that something i can do with some standard config with the mios gui config tool or some text editor or do i need to do some programming ? (which I know nothing about so would need tips / pointer examples) p.s. Also read about banks (if using a bank stick). Could this be a solution . Could I make a button that automatically save the led status , and switches to the second bank and the reverse , or is this bank stuff only intended for pots. Switch needs to be almost immediate for live performances so waiting a minute for bank saving would not work.
