I am starting to program a CTRL interface for my Tascam controller....
I found two documents regarding midi implementation.

One i understand because it hold midimessages.
https://tascam.com/content/downloads/products/229/native_mode_protocol_e_1_60.pdf

The other i am not quite sure what is about, could someone explain, i think it is about messages but unsure howto interpretate the columns
Especially the # column is it program value and their respective note on/off, to set buttons LCD's?
https://tascam.com/downloads/tascam/229/default_midi_control_values_1_00.pdf


Now i wrote some functions for Tascam FW1884 midicontrol host -> FW1884 over firewire midiport.
I use HTML checkboxes "onChange function" and pass ID and checkbox value "true/false" to the function that then send a message to the FW1884 that should lighup a led to show that mute changed.

However "nothing happens for any of the functions NO LEDS LIGHT UP".. .
Maybe i send to the wrong port or my messages malformed?
Or the Tascam device must be in a certain "mode" to receive the messages?

Anyone familiar with the Tascam FW1884?

function getPortIndex(){
var e = parent.document.getElementById("out_portsel");
for (var i=0;i<parent.out_portsel.length;i++){
if (e.options[i].value=="FW1884 Control"){ctrlportindex=i; break;};
}
}

I got alot of functionality working both ways control strip and leds, now i try to fix fader_position but the cryptics of the midi manual.....
I do not have a clue about what they want or mean below, i formatted message
settingChange=[0xBF,0x4F,0x7F,0x5F,0x70];
Channel 1 but complaint no valid message.,

Could someone decrypt a valid message frow "midi manual" below

1. FADER_POSITION: BF 4x vv 5x ww x = [F, 1, 2, 3, 4, 5, 6, 7], (channel, except
for the first channel which is mapped to “F”)
vv = [0..7F] (7 MSB’s)
ww = [00,10,20,30,40,50,60,or 70]
(3 LSB’s of fader ADC shift left)

"7 MSB, 3 LSB WHAT DO THEY MEAN?"

It’s pretty worth enough for me. Thanks


I uploaded, it is just transport play, rec , pause, stop that works and the functionality for select, rec, mute and solo.
I want the motorised faders? sliders to work, but i can't decrypt their documentation.
So i think it will be pan to start with.

Reading the midi manual about the "fader controlled?" encodings "buttons to the left", i can not see there is messages from host to set the pan.
"Actually i am clueless howto pan channels "from the device" altogether."
But maybe the pan setting within a subset of the message to set the faders, but the manual doesn't tell?
