Sneed synth is a genre of synthesizer music.
Sneed synth MUST be made using Nyquist and/or Sneedacity.
Musically, Sneed synth is a work in progress, and artists are welcome and invited to develop the genre.
It is customary to distribute Sneed synth with a permissive license of your choice, with the +NIGGER rider.
This is the first Sneed synth song to ever exist. Enjoy.
Get nyquist, get an editor, and use the following starter code:

;; SNEED SYNTH TUTORIAL
;;
;; This is a song synthesis script. It specifies what audio to
;; generate, what audio to import, and how to combine it into
;; the final song.
;;
;; Substitute the path here with a relpath to the Sneed library
;; covered previously. It supplies some of the functions used
;; here.
(load "./lib/sneed")
;; RENDERING ADAGIO: NOTE BY NOTE
;; Channels are specified in Adagio with the `V' directive.
;; Here, the channel is used to determine which instrument to use.
;; Add additional instruments in this conditional below.
;;
;; Currently, channel 1 is a bowed instrument (cello, violin, etc.)
;; channel 2 is mandolin
;; channel 3 is flute
;; all other channels are a generic plucked instrument.
;;
;; Feel free to add more channels with different instruments. There
;; is no need to delete these three already here; Adagio supports
;; about 128 voices (channels)!
(defun sneed-note (chan pitch)
(cond ((= chan 1) (bowed-note pitch))
((= chan 2) (scale 0.2 (mandolin pitch 1.0)))

;; SONG SPECIFICATION
;; Here, we describe the song.
;; We write parts per-instrument, so that we can apply overall
;; effects to just one instrument at a time if we wish.
;;
;; We then mix the parts of one song segment together, in order that
;; trailing rests aren't lost, and sequence the song segments
;; in the end for the final song.
;;
;; The composition of `snd-normalize' and `sum' works well to mix
;; song parts together.
;;
;; `seqrep' repeats a behavior (the result of `cue'; see docs),
;; enabling us to repeat song segments easily.
;;
;; `seq' lays song parts end to end to make the final song.

You will compose parts in Adagio, which is more or less sheet music.
Adagio is well-documented in the Nyquist documentation, but here's a chord progression to get you started:
!TEMPO 100
!CLOCK
D4 W V1, F4 W V1, A4 W V1
C4 W V1, E4 W V1, G4 W V1
A3 W V1, C4 W V1, E4 W V1
C4 W V1, E4 W V1, G4 W V1
Run the synthesis program (starter code above) with the ny interpreter, like so:
ny < synthesis.lspYou must be in the proper directory that the relative paths in your code are valid.
