- ROM retuning — patching a tracker's pitch table techniqueOverwriting the block of precomputed pitch values inside a tracker's ROM, so that every note in the sequencer plays at a frequency you chose. It is how alternative-tunings are done on the game-boy , and it is also the …
- Alternative tunings — chip music outside 12-TET conceptTwelve equal semitones per octave is a choice, not a law, and on most chips it is a choice made by a lookup table in the ROM rather than by the hardware. Change the table and every note in the tracker moves — the …
- Abrasive personThe person whose idle question started Game Boy microtuning: "can LSDJ be retuned to non-standard tunings?" The answer, in his own account, took "a few minutes in a hex editor and half an hour in Perl" and became …
- little-scale personSebastian Tomczak, chipmusician and prolific tutorial writer, whose 2008 blog post How to: Prepare Samples and Create LSDJ Kits is still the reference the chipmusic-org kit threads point at five years later — …
- nitro2k01 personGame Boy hardware and software specialist, and one of the recurring technical voices on chipmusic-org — the person who answers why the chip does that , usually with the register-level reason.
- little-scale — Abrasive on LSDJ Microtuning (2009) summarylittle-scale reposts abrasive 's own announcement of lsdj_tune , the script that turns the hand-editing of the previous day's post into a one-line command. Unusually for this blog, everything is in the text.
- little-scale — Let's Tune the Game Boy Like a Japanese Koto (2009) summaryA commission, and the clearest worked example of a just (ratio-based) retune in the cluster: the whole ROM tuned to the pentatonic hirajoshi scale on A. The spreadsheet screenshot shows every intermediate column, so the …
- little-scale — LSDJ Tuning Tables (2009) summaryFour sentences and two pictures, and the pictures are the post. They show where lsdj 's pitch tables live in the ROM — the prerequisite for every rom-retuning job that follows on this blog.
- little-scale — Microtonal Chipmusic Compilation, call for tracks (2009) summaryShort, and included because it is where little-scale states the point of the whole 2009 tuning project and lists the routes into it — a contemporary bibliography of chip microtuning as of December 2009.
- little-scale — Nanoloop Tuned to 18-TET, Hacked ROM (2009) summaryThe earliest post of the cluster, a day before the LSDj tables, and the one that explains the arithmetic in words. Same technique, different tracker: nanoloop 1.3d retuned to 18 equal divisions of the octave.
