'HardwareSerial' was not declared in this scope

EDIT: just realized that Attiny 84a doesn't have hardware serial. I read the information on it wrong. D'oh!

Decided to start my project over with an Attiny 84a rather than an 85 so I don't have to mess with softserial. Now when I try to compile I get 'HardwareSerial' was not declared in this scope.

#include <MIDI.h>

MIDI_CREATE_DEFAULT_INSTANCE();

void setup() {
pinMode(2, OUTPUT);
}

void loop() {
digitalWrite(2, HIGH);
delay(500);
digitalWrite(2, LOW);
delay(500);
}

From what I can read in the Arduino core code, HardwareSerial is disabled for ATtiny chips, which only have a USI (Universal Serial Interface), which does not use the same kind of registers as a dedicated UART, which is what the HardwareSerial interface relies on.
