Добрый день , нашел на просторах интернета вот такой проект.
Решив не бросаться сразу на амбразуру попробовал просто передать MIDI с помощью официального примера через Serial MIDI Converter и midi_yoke всё завелось на скорости 19200.
Но когда попробовал пример из первой ссылки столкнулся с тем что данные на любой скорости передаются с ошибками. По факту доходит не читаемая белиберда
Подозреваю что дело в функции Serial.print используемой в midi drum . Если заменять Serial.print на Serial.write как в примере то ошибки передачи пропадают, но передаются сразу все ноты...
Буду рад любым советам или просто соображениям по теме
