Yes, i have considered this, although i do plan to send relative inc/dec signals and use no LED-rings. I have not really looked into this yet, i am not sure what date can be made available from Logic to controll the state of DOut pins.
Shure would be nice if a led could show me when a EQ-Band or Insert-Slot is turned on.
I plan a very custom box and might start a new threads as soon as i have a couple of things sorted out and did a real layout. Since i have a bunch of PICs here using multiple cores is not so bad for me and i figure it would be the most easy approach.
Right now i see 16 encoders, 28 buttons, and 1 analog Fader. Problem is, i want the functionality described with the EQ-Bands for the dynamics (gate, compressor, limiter) as well.
I think i could do this with two cores without writing my own application. I still like to learn some programming but i am a realist and i don´t know if i ever will. Although since this setup needs no programming on the fly, no LCD, just one “setup and forget it” it might be quite good for a starter.
Main section:
Volume (fader), just passive, i can live with the parameter jump on this/will use soft takeover
5 Encoders:
Pan
Send 1
Send 2
Select track left/right
Focus Insert up/down
11 Buttons
Mute
Solo
Arm
Bypass Insert 1-8 (8 buttons)
Then there will be the eq section
2 Encoders Output / Mix
8 buttons to select up to 8 Bands (with leds showing the state)
3 Encoders Frequency, Gain, Q
1 Button Band on/off
And a Dynamics section:
3 Buttons to select target (like the Band-select buttons on eq), Gate, Compressor, Limiter
6 Encoders Attack, Release, Threshold, Ratio, Mix, Output
maybe 5 more buttons for related functions.
