Final Song

Tutorial Groove is complete. This page is the payoff for the whole walkthrough: the four-channel arrangement from Sequencing, phrase variation from Modifiers, and the wobble / spark / slide presets from Effects.

Modifiers are what make the finished track feel longer and more polished — the same few patterns are reshaped across an eight-phrase form instead of looping a short A/B block.

Form (8 phrases)​

Each sequence lists eight 16-step phrases (channels stay locked). Rough arc:

PhrasesRoleWhat happens
1–2OpenA/B with lead_b:rot(2), harmony_b:rev
3–4BuildReturn to A, then lead_b:oct(+1)
5Peaklead_c (vibrato) over a simple harmony_pad — less clash than busy arps
6BreakLead/harmony rest; bass + drums_fill keep the pulse
7–8SettleFamiliar lead_a / harmony_a, then lead_outro and rests on bass/drums

Empty patterns (lead_rest, harmony_rest, …) and lighter alts (harmony_pad, drums_fill, lead_outro) give the second half air so stacked modifiers do not turn discordant.

Ideas to try​

After you Copy the song, experiment:

  • Lengthen the form further with (lead_a lead_b:rot(2))*2 style groups, or add a ninth/tenth phrase
  • Chain more modifiers, e.g. harmony_b:rev:oct(+1) or drums_b:rot(4):rev
  • Change bpm 140, pulse duties, or the bass wavetable
  • Tweak effect presets — deeper vibrato, arp:3,7, slower port
  • Pan a phrase or add another effect from the Effects reference

Other sound chips​

The notes, patterns, sequences, and most effects in Tutorial Groove are chip-agnostic — the same musical material can target another backend by changing chip and rewriting the instruments (and channel map) for that hardware.

For example, on the NES you might keep lead_a / bass_seq as-is but define type=pulse1, type=triangle, and type=noise voices with NES fields instead of Game Boy duty / wave= / uge_note. Channel counts differ too (NES has five voices including DMC; SMS has three tones plus noise). Start from the Game Boy song, then follow the guide for your target chip under Sound Chip Plugins.
