Is feat/2.0.0 compatible with FortySevenEffects/arduino_midi_library?

[alf45tar]

Both create a MIDI object. Can they coexist?

Thanks al45tar

feat/2.0.0 uses 47Effects/arduino_midi_lib (branch feat/4.4.0see src/utility/midi_feat4_4_0) thru static polymorphism.

So the MIDI is an abstract MIDI object (the transport Layer has been removed) and AppleMIDI fills in the transport layer (ipMIDI is another transport layer, or Serial, or BLE,... - all using the same abstract MIDI core).

(in src/utility/midi_feat4_4_0 MIDI.h search for Encoder - this will be filled in by the second object: AppleMIDI, ipMIDI, ...)

Makes sense?

[alf45tar]

Can you provide a small example how to use a couple of transport layers?

[lathoub]

Not sure what you are asking for.

Examples like USB, BLE, ipMIDI - or actual implementations? (or are you asking how static polymorphism works in this case?)

Here is an easy one to learn a bit of all: ipMIDI

[alf45tar]

How can I send a MIDI message (like a NoteOn) via AppleMIDI and via Serial in the same program? The command is always the same MIDI.sendNoteOn(note, velocity, channel). How can I change the name of MIDI object to differentiate different trasport layer?
