|delay: byte, rate: byte, type: byte (0-15)
|When <code>rate</code> is 0, it will be translated to 256 ticks.
The interpretation of the first parameter may change to depth depending on 0xF3.

|amount: signed byte
|The pitch can be changed in the range of one octave above and below.The <code>amount</code> is the multiplicand for the playback frequency, not a log-based parameter like cents. For example, when the <code>amount</code> is 127, the pitch will be multiplied by 127/128 (about +1 octave). Negative value will lower the pitch.

|Turn On Alternate Voice
|2
|release_rate: byte(0x00-0x1f)
|This instruction allows subsequent notes to be played on two alternating channels. At the same time, the ADSR release rate will be set to the specified value. A free voice channel is required to work.
Check "Opening - Bombing Mission", "Tifa's Theme" and "Fortress of the Condor" for actual usage.
