Hi,
I'm running these 6 digital servos from my Arduino Leonardo, using midi cc#7 from my DAW/Logic Pro X 10.4
Description:
High quality robot servo with advanced interior design and precision potentiometers.
Dual-ball Servo which means one is Driving shaft and another is virtual axis (supporting function).
High torque and 270 degree rotation, barely absent and dead zone.
Weight: 60g
Size: 402040.5 mm
Speed:0.16 sec/60°7.4V
Locked-Rotor Torsion：15Kg.cm 6.6V; 17Kg.cm 7.4V
Voltage: 6-7.4V
Unload Current: 100mA
I using 6 volt 6amp ac/dc adapter
I have attached my breadboard schematic
(the black wire goes to the gnd of the Lenardo)
the code does pretty much what I want expect for 1 thing I can't get the servos to operate on different midi channels at the same time, each servo independently from the other each on there own midi channel. if all servos are connected to one midi channel at the same time they all move the same, at the same time but thats not what I want. I can only get one midi channel(or 1 track) in my DAW with cc7 events activated, when engaging other midi channels at the same time with cc7 automation on those channels the servos violently start jerking.
I've only been at this for 2 + months so I know I screwed up the code some where.
Serial Monitor and Midi Monitor app and DAW/Logic Pro X all print out that the the correct event info is being sent from my DAW to the Leonardo for example

I know its probably easy to fix , but I have tried to for days but, can't get it figured out, any help would be much appreciated. and any suggestions on a better way to code , to achieve what I want, I'm all ears!
if this entire post makes no sense, I have mental fatigue from reading so much, on learning how to code!, in the last two months.
