SMARTWAV 2

MIDI Mode

SmartWAV2 processor is a sophisticated multi-task audio processor, it

can playback up to 14 individual .wav tracks/songs/voices at the

same time, triggering, decoding, sampling, mixing are automatic

processes that can be controllable.

The module offers 8(eight) modes of operation; selection between

modes is by setting the external pins M0, M1 and M2, this document

covers only the Polyphonic Slave Standard Serial Mode 4(MIDI Mode),

for more operation modes please refer to the document SmartWAV2-

Datasheet.pdf.

It is strongly recommended to be familiar with the MIDI protocol, be

sure to understand some basics of the MIDI messages structure.

MIDI is a protocol primarily designed to communicate musical

instruments using commands or messages, MIDI does not send any

actual physical audio data or sounds like RCA cables, ¼” Jacks or

even wireless Bluetooth connections, MIDI messages are just

instructions/directions that are processed by other MIDI devices.

In MIDI protocol there is always one MIDI transmitter device and one

or more MIDI receivers at the time, MIDI is designed to connect up to

16 different devices/instruments, each instrument/device must be

assigned to a different MIDI channel (1 to 16) to not interfere with other

devices connected in the chain (MIDI channel is similar to the address

number of a house). MIDI devices only process MIDI messages that

match their selected MIDI channel and non-matching channel

messages are just ignored.

There are MIDI devices that can act only as MIDI-OUT transmitters,

some other devices can only work as MIDI-IN receivers(SmartWAV2),

and some other devices can do both, but only one device can be

the transmitter at the time while the other 15 devices must act as MIDI

receivers, the next illustration shows a typical chain of MIDI devices:
