How to handle dual color LEDs???

MIDIbox SEQ

Hi

I’m prepared to build a SEQ V4 which makes me very excited…

Core Module, DIN and DOUT Modules, Knobs, Encoders, PS … almost everything is ready!!!

There is just ONE uncertainty here after reading back and forth trough device descriptions, forum and MBSEQ_HW.V4:

How to handle the LED’s of GP Buttons and Step-Indicator???

I will use these GP (step) buttons: Buttons

Either I will use dual color LED installed to the buttons or standard LED to the buttons plus a separate Line of 16 LED’s for step indication.

The concepts are some what different. For the first unmuted steps LED have to be de-illuminated when step-indicator comes to respective step. Whilst for the second option with a separate line this is not desired!

My quenstions are: Are both options possible? and what are the respective configurations I have to make in MBSEQ_HW.V4?

can I use this section for either option? (line 47)

DOUTs for Dual Color option:

GP_DOUT_L2_SR 0

GP_DOUT_R2_SR 0

or do I have make my configurations within here: (line 61)

Optional BLM Matrix

isn’t the later section intended for the usage of separate dual color LED’s for each track of a track-group? I only want the respective track highlighted by the track selection buttons to be indicated by the LED’s

These lines:

# number of first and second DOUT shift register used for GP LEDs

GP_DOUT_L_SR	3

GP_DOUT_R_SR	4


# DOUTs for Dual Color option:

GP_DOUT_L2_SR 0

GP_DOUT_R2_SR 0

are enough for 1x16 dual color LEDs or 2x16 single color LEDs.

As for de-illuminating of 1st color of dual LED, I don’t know how it’s handled. In the BLM section there is an option for this…
