OK I just found out what Martin W already mentioned a while ago in the original thread: Spark CDM uses different midi message FROM the computer TO the hardware. I collect them in a seperate post. then I will try yr new script.

i have another idea, but don't have much left ;)

Unselect the script, and use the spark as a midi controler.
In live select for a track the spark as output instrument.
Then create a clip in wich you put F-1 notes vith different velocities.
It will help us to know what's going on

Pad 9-16: same as Pad 1-8.

what i found out with a little Max patch:
if you send a midi note with pitch E-1 (16) and a velocity between 0 (or 1?) and 64 you can turn on ALL buttons, pads, patterns, groups, etc on the hardware. I just can't figure out how to turn them OFF again.

will now test your new script...

i installed it. what do i do now? how do I know what works?

can you try this script please?

the same as before:s

If you press play on the live software, i might light the pattern button from 1 to 16

can you tell me what are the velocities associated to the patterns button from 1 to 16?

0-15 (although 0 doesn't work yet. but 1-15 lit up buttons 2-16)

this is what happens but I just don't understand what this proves. if I deactivate the script this still works as long as I am in Spark Mode. if i switch to Midi Mode the hardware shows nothing.

i don't understand :
The spark doesnt have an hardware sequencer so if you see the led on and off, it means that
1- the spark software is lanched
2-the script is working

with no script the sparkle surface stay with all led off is it different with the spark ??

OK i need to sleep this over. it's getting late and my brain is melting...

however I found out something important!
to turn ON e.g. button 2 you have to send [144 16 1]
to turn OFF button 2 you CANNOT send [144 16 0] (as Note OFF) but instead you have to send [128 16 1] (the "real" Note OFF message). did you know that already?

i don't understand :
The spark doesnt have an hardware sequencer so if you see the led on and off, it means that
1- the spark software is lanched
2-the script is working

with no script the sparkle surface stay with all led off is it different with the spark ??

time to make a little pause and clarify where we are, and what we want to do

usually when you are using midi message you send a triplet ( AA , BB , CC)
AA is the type of signal : 144=144+0 (90 in hexadecimal) for a note on on channel    and 128 ( 80 ) for a note off
it can be decompose this way : 144 is the note on message and 0 is the channel ( first channel
a note on message on the second channel has a value of 145
BB is the tone ( 0 - 127)
CC is the velocity ( 0-127)

In a perfect world, the midi normalization has been made to make everything easy :)

Here it is note the same.
The spark uses two different way to work
----------From the spark to the computer :
for pads ( the 8 big buttons) it is note event from C2 to G2  ( with velocities )
for button it is different : the note sent by the spark is a F-1 ( 17  in decimal, 11 in hexadecimal)  and the value of the velocity is related to one button from 1 to ???<127
encoder->we will see this later, it seems to work in a normal way

---------From the computer to the spark
For pads > it works just like buttons
for buttons : the note sent is E1 ( 16 in decimal , 10 in hexa ) and the  note off signal (128,16,0) for exemple to turn off the light of the pattern button 1

Do you agree with me ?

I am familiar with all this MIDI message definition stuff. In my world (MaxMsp) I am just used to use Velocity = 0 as Note Off which is not 100% standard conform. that's why it took me a while to figure out how to turn off any button on the Spark hardware.

velocity from the computer to the hardware definitely worked from 1 (step 2 of the 16 step buttons) until 68.
one last thing i need to find out is how to access Step 1!

Do you agree with me ?
i almost agree:
for all (i think) buttons, 8 pads, 8 white LEDs :
to tun on the note sent is E1; the velocity goes from 0 - 68 => 144 16 [0-68]
to tun off the note sent is E1; the velocity goes from 0 - 68 => 128 16 [0-68] (NOT 126 16 0!)
so the velocity for Note On (144) and Note Off (128) need to be the same.

i am putting all my findings into a Max For Live device to make more research easier. I could send it to you or anyone else with a Spark CDM hardware to test/verify.

I tested the encoders on the Spark software to see what they send out to the hardware. It seems it's all sysEx data! I really hope we can avoid having to deal with SysEx. But it's probably not necessary anyway, right? I hated my few programming excursions into sysex...

Encoders doen't have to get information from the software to the spark
They are infinite rotative encoder, it means when you rotate clockwise  65 and anti-clockwise it is 63 f(from what i have understood from your posts )

As they are no leds to know the value of the encoder on the hardware, it is note usefull to work on the datas sent to the spark.
I think the sysex value are used to modify the lcd screen

ah yeah, the sysex stream is for the screen! well, that would be pretty rewarding to get this to work as well... in a remote future =)

63 and 65 are the values for controller values in relative mode according to the MIDI protocol definition. the software takes care of the rest.

i have written a new script
sources

whats it does :
It creates an empty clip on the first track if it works
when you press a key it analyses the key pressed, and light two buttons/pad : the one pressed, and the one what have the value next to it

For exemple if i press button 1 it light the button 1 and 2

can you tell me if it works ?

didn't get it to work. when does it create this clip? immediately when i open a Live project? When I press Pad 1?

didn't get this to work either.
