##tune

//A stands for the first channel, there is channels from A-Z
//starting with @ are commands, uppercase are builtin, lowercase are custom(look at synth part)
A @I0 @V0.5 @c0.3 @r0.5 @f2 @m4 @O4

// lowercase letters from a-g are notes, a number after it is the notelength(eg. 4=quarter)
// < and > lowers and raises the octave
// a "t" after a note declares a note to be part of a triplet
A d4 d < a8t ft at > d4

//commands can be changed whenever
A @c0.2 @r0.7 @f4 @m8
A d4 d < a8t ft at > d4

A @c0.5 @r0.5 @f0.5 @m4
A d4 d < a8t ft at > d4

//instead of just a number a channel command parameter can be a sequence
//the sequence is written in [val val val]speed, it iterates over all values
//every single step has the length of a note of the value "speed"
//so @f[2 0.5]16 means that @f first is 2, one 16th note later 0.5, one 16th note later 2, and so on
A @c0.3 @f[2 0.5]16 @m4
A d4 d < a8t ft at > d4
