The Agenda Music Format is an obscure sound driver only found in two Japan exclusive games: The Amazing Spider-Man: Lethal Foes and Doraemon 4: Nobita to Tsuki no Ōkoku. This format features commands not present in the N-SPC sound driver, such as changing the internal main volume.
TODO: Do more documentation, I mean, it needs a lot of how commands work.

||Echo VBits / Volume||
xx = Tie Time yy = Tie Delay
Tie keeps the sound while commands happen.
xx = Tempo
Specifies the playing speed of the song.
Main Volume (
xx = Main Volume
Sets the main volume in the DSP, meaning it will affect the volume of sound effects, as well as echo volumes functioning differently.
In Doraemon 4, a main volume of $32 is used for the Epoch logo whereas the rest of the tracks use the $3C main volume.
xx = Instrument
Changes the sample and ADSR based on instrument info.
xx = Channel Volume
Set the channel volume. The higher the value is, the louder the sound is.
xx = Finetune
Sets the finetune on a specific channel.
xx = Legato/Channel Cutoff(?)
Most likely sets legato or channel cutoff. Modified it in a Doraemon 4 SPC and weird things happened, so I'm not sure about it.
xx = Vibrato
Makes the sound distorted
xx = Resting Time
Stops the channel for a specific time.
xx = Pan
Sets the left and right volumes of a specific channel. This was done for stereo.
Pitch Bend (
xx = Pitch Bend
Slides the pitch to a specific note.
Echo VBits / Volume (
xx = Echo Enable yy = Left Echo Volume zz = Right Echo Volume
Specifies the channel and volume at which echo is enabled.
Echo Parameters (Delay, Feedback, FIR Filter) (
xx = Echo Delay yy = Echo Feedback zz = FIR Filter(?)
Sets the echo details.
