need help on projects !!!

[alexglvr]

Hello,

i am about to start a project. The goal is to command the registeries (i am not shure of this word..., let's say the 'sounds') of a digital pipe organ (computer software)...

i will then have 1 switch (single position) and 1 led per sound. when a switch is pressed, the associated sound must be put on/off. The corresponding led must follow the state of the sound... at this state the midiio128 seems to be a good choise...

a bit more complicated: i can save configurations on the organ software. i would like that, when a configuration is recalled, the leds associated to the good sounds light on...

about the midi configuration :

computer (which plays the sounds): channel 1

keyboard 1: channel 2

keyboard 2: channel 3

keyboard 3: channel 4

foot keyboard: channel 5

but what about the midibox? the Dout for the leds must respond both to the computer and to the midi box itself... is it possible with the midiio128?

a last question : is the LTC module necessary? i already have a midi chain, and i does not anderstand the aim of the rs232...

thank you for your help...

Sincerely,

Alex
