Multiple MIDI Input

[urbanspaceman]

Hi, i have a MIDI project to develope

I need, multi MIDI Input (Three)
i see on the MIDI example that there is no way to tell at the MIDI.begin function on which pin receive the midi data.

There is a modified library or other thing to do to achieve this function?
Thanks

if this work https://github.com/FortySevenEffect...lob/master/examples/DualMerger/DualMerger.ino
i've found the solution (maybe)

 

[urbanspaceman]

with this piece of code


/* serial port input */
MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, midiA);
MIDI_CREATE_INSTANCE(HardwareSerial, Serial2, midiB);
MIDI_CREATE_INSTANCE(HardwareSerial, Serial3, midiC);

i get the error
'Serial1' is not a type

any advice on this?

Example code section... define type and begin... ??

@oddson i don't know

MIDI implementation seems different to serial...

/* serial port input */
MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, midiA);
MIDI_CREATE_INSTANCE(HardwareSerial, Serial2, midiB);
MIDI_CREATE_INSTANCE(HardwareSerial, Serial3, midiC);


Serial
#define HWSERIAL Serial1

This is the source sketch (for arduino)
same error


#include <MIDI.h>

// This example shows how to create two instances of the library to create a merger.
// There are two MIDI couples of IO, A and B, each using thru and merging with the
// input from the other node. The result is the following:
// A out = A in + B in
// B out = B in + A in

#ifdef ARDUINO_SAM_DUE
MIDI_CREATE_INSTANCE(HardwareSerial, Serial, midiA);
MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, midiB);
#else
#include <SoftwareSerial.h>
SoftwareSerial softSerial(2,3);
MIDI_CREATE_INSTANCE(HardwareSerial, Serial, midiA);
MIDI_CREATE_INSTANCE(SoftwareSerial, softSerial, midiB);
#endif

void setup()
{
// Initiate MIDI communications, listen to all channels
midiA.begin(MIDI_CHANNEL_OMNI);
midiB.begin(MIDI_CHANNEL_OMNI);
}

void loop()
{
if (midiA.read())
{
// Thru on A has already pushed the input message to out A.
// Forward the message to out B as well.
midiB.send(midiA.getType(),
midiA.getData1(),
midiA.getData2(),
midiA.getChannel());
}

if (midiB.read())
{
// Thru on B has already pushed the input message to out B.
// Forward the message to out A as well.
midiA.send(midiB.getType(),
midiB.getData1(),
midiB.getData2(),
midiB.getChannel());
}
}

Maybe see this example https://forum.pjrc.com/threads/41602-Teensy-3-6-Uarts?p=131047&viewfull=1#post131047
