Hi there,
first of all, I have to tell you that I am not very comfortable with programming. I am still learning.
Here is my problem.
I have made the Gijs's MCG without any problem. It works well. But now I would like to modify it to be able to control an akai headrush E1.
The first mod I'd like to make:
I have done several attempts to add a second LED which would blink in time with the midi/sync24/... clocks.
Every test I made wasn't accurate att all and the tempo LED (the one already there) changed his blinking frequency as I started the second LED. I tried with delay() but of course it delays other things, with millis() but I lost myself in calculation as I need a short LOW and long HIGH blinking (or the opposite)
I someone could help me with this, that would be great.
At the end the project would be something like that:
-plug the two switches of the headrush in the arduino (to tell the arduino what the headrush is doing and to control the headrush) since the two switches are dpdt footswitches with only one side used by the headrush.
-write a code for the arduino to send a start/stop message to the headrush in time with the other gear connected and acting differently if the REC button of the headrush is ON or OFF.
I am sure this is not so hard but I am bad enough not to know from where I can start all this.
here is the MCG I am using:
