lsdj wave cruncher
defensemech's blog post about it
patch in your own wavetables for lsdj. lets you do more as a wavechannel than as a sample kit.
Saturday, June 13, 2026
run multiple lsdj instances in the browser
only works on desktop because you need to drag the roms in.

gameboy link cable breakout pcb board for 2$
solder on some 1x6 m, f, or double male headers
I think il be able to make an arduinoboy from a promicro with just this and a link cable.
tempted to get the hobbychop one for 70 cad but its alot of money.
they have a breakout for 6$ but its US I think with tarrifs and shipping its 20$ :(
looking at cutting up my link cable and crimping on some dupont M connectors.

droid pad
use android tablet like a gamepad to control linux using websockets
or ble droidpad companion
could trigger keyboard shortcuts
spessasynth web soundfont exitor
spessasus soundfont editor github
cant really use on phone but sounds like it could be interesting il have to check it out deeper. looking at android theres not any options i know of other than maybe somehow running polyphone in a linux emulator?

FL studio getting multiple plugins to show at once

lsdj patcher
lets you load custom fonts and edit colour pallates. for fonts the y2k is classic but I like the DOS, Protracker, and Renoise themes for custom. for Colour pallate I went with the solarized dark and modded it to be more greyscale and with a dusty yellow cursor instead of purple.
it exports songs as lsdprj. For lsdjsng export I think I need to use retroplug instead.
best gb emulator on linux mint 22.2
went with v 3.75 ubuntu 22.04 version because sdl3 wasn't found on the lastest build.
mgba sound quality sucks, retroplug is ok but the overhead of it running within wine cranks my fan. This is the best emulator on linux iv've foudn so far. was thinking about getting gambatte but its only available on sourceforge and i don't trust like that.
lsdj converter in browser
I use retroplug on my computer to open lsdj songs and export .lsdjsng because it doesnt work with .sav alone
the lsdj wikion linux mint the web apps tool lets you launch websites like apps.
is LSDJ worth in in 2026?
3 things got me feeling like a time traveller from the year 2000.
- ska
- microkorg
- lsdj
We have alot more options now that didn't exist back then.
I didn't have a gameboy back then. I always wanted to get into lsdj.
the costs add up.
i got a free gba with no power adapter and a swollen battery.
- flashcart 23$
- battery 10$
- charge cable 7$ + linkcable
40ish bucks just to get lsdj running.
but I want midi out. lsdj patches lets you load lofi samples but that sucks and then gba
needs another audio dongle to get 3.5mm out.
the idea of a portable handheld battery powered tracker gets less portable when a million dongles and power supplys get reqired.
the idea of repurpusing a game console for music doesn't make sense when all these costs pile up.
2 options to get midi:
- arduinoboy prebuilt 70$
- arduino leonardo + midisheild on ali 20$
could potentially save 50$
- probably have to edit the arduinoboy firmware to get the pins correct
- have to cut up a link cable (hobbychops arduinoboy comes with edge connectors)
-build a case to mechanically support the custom cable so it doesn't rip off some things that make it easeir to deal with3>
-gearboy
-lsdj patcher
- lsdj song to midi conversion tool to get midi out
- retroplug for audio syncing route.
wish retroplug could do it all for me but on linux its not working idk why I cant get he midi out
gearboy + the midi conversion tool is enough for me to want to get gba running again. dont need to shell out 70$ for the arduino boy

digiwaves decent sampler
made an insturment for the decentsampler vst that can also run on ios. Its 64 digital waves you can swap between using the modwheel. If you rename the .dslibrary file to zip and extract there is a .sfz mapping which uses the same samples but maps them differently. The soundfont has no UI but its got a lowpass filter and amp and filter egs that correspond to the mk. The sfz is monophonic while the decentsampler patch is polyhonic.

deflemask triplets in 12 lines instead of 8
with a pattern length of 48 with each beat being 4 lines
set the speeds both to 2: 09-02, and 0F-02 to align with 8th note quarter notes
deflemask triplets using speed commands
in 2 columns set 09 01 and 0f 01
then to reset back 09 03 0f 03
that lets you sequence like regular quarter notes across 8 lines

Timing Systems in the History of Music Trackers
In the history of music trackers (especially on early computers like the Commodore 64 and Commodore Amiga), timing systems evolved because different hardware offered different ways to measure time. Terms like PPQN, CIA, VBlank, NTSC, PAL, and LPB refer to how trackers scheduled musical events such as notes and effects.
1. VBlank Timing (Early Trackers)
VBlank = Vertical Blank interrupt
Early trackers synchronized playback with the screen refresh interrupt.
- The video chip triggers an interrupt every frame.
- The music routine runs once per frame.
Frame rates depended on TV standards
- PAL: 50 Hz (50 interrupts per second)
- NTSC: ~60 Hz (59.94 interrupts per second)
These standards come from analog television systems used by machines like the Commodore 64 and early Amiga 500.
Effect on tracker timing
A tracker row advanced every N frames.
Example (classic Amiga trackers):
Speed = 6
PAL 50 Hz
Row duration:
6 frames / 50 Hz = 120 ms per row
Pros
- Simple
- Stable with graphics
Cons
- Different speed on PAL vs NTSC
- Limited timing resolution
This system was used in early trackers such as Soundtracker (1987).
2. CIA Timer Timing (Amiga Precision Timing)
The Commodore Amiga had CIA chips (Complex Interface Adapters) with programmable timers.
Later trackers used CIA Timer A instead of VBlank interrupts.
Why?
CIA timers allow arbitrary interrupt rates, independent of video refresh.
Example:
Timer frequency ≈ 709379 Hz / divider
This allowed:
- More precise BPM
- Same playback speed on PAL and NTSC
Trackers such as ProTracker used this technique.
Pros
- Hardware accurate timing
- Independent from video
- Higher precision
Cons
- Slight CPU overhead
- Required careful hardware programming
3. LPB (Lines Per Beat)
LPB = Lines Per Beat
This concept appeared in later trackers during the PC era.
Trackers such as FastTracker II and Impulse Tracker separated:
- tempo (BPM)
- pattern resolution
LPB defines how many rows equal one beat.
Example:
BPM = 125
LPB = 4
Meaning:
- 4 rows per beat
- 16 rows per bar (4/4)
This makes timing more musical and flexible.
4. PPQN (Pulses Per Quarter Note)
PPQN = Pulses Per Quarter Note
This timing concept comes from MIDI sequencing rather than trackers.
Common MIDI timing resolutions:
24 PPQN
96 PPQN
480 PPQN
960 PPQN
Higher PPQN values give finer timing resolution.
Later tracker-inspired software and modern trackers adopted similar high-resolution internal clocks.
Examples include modern trackers and DAWs such as Renoise and OpenMPT.
5. Relationship Between These Systems
| System | Used In | Resolution | Hardware Dependence |
|---|---|---|---|
| VBlank | early Amiga / C64 trackers | low | tied to video |
| PAL / NTSC | video standards | defines frame rate | hardware |
| CIA timer | later Amiga trackers | medium | hardware timer |
| LPB | PC trackers | high | software |
| PPQN | MIDI / DAWs | very high | software |
6. Typical Classic Tracker Timing Formula
For ProTracker-style trackers:
row_time = speed × tick_time
Where:
tick_time = 2.5 / BPM seconds
Example:
speed = 6
BPM = 125
Tick time:
2.5 / 125 = 0.02 s
Row time:
6 × 0.02 = 0.12 s
This produces the famous 125 BPM / speed 6 groove used in many Amiga modules.
7. Historical Timeline
1980s
- VBlank timing
- PAL/NTSC differences
- Soundtracker era
Early 1990s
- CIA timer timing
- ProTracker era
Mid 1990s
- PC trackers adopt BPM + speed system
Late 1990s
- LPB introduced
2000s+
- PPQN-style internal clocks
Summary
- PAL / NTSC → video refresh standards
- VBlank → music tick tied to screen frame
- CIA timer → programmable hardware timer interrupts
- LPB → musical resolution (rows per beat)
- PPQN → MIDI timing resolution
understaning clock speeds in sunvox and deflemask
deflemask default is ntsc basetime 1 = 150bpm
sunvox default is 125 6tpl
- to match deflemask to sunvox:
set to pal, increase basetime from 1 to 2
- to match sunvox to defle:
lower tpl from 6 to 3 and increase bpm to 150
for quarter note (8 lines) to be equivalent
sunvox at 6tpl is half the speed of deflemask pal basetime 1.
increasing basetime lowers the speed
while decreasing the tpl increases the speed

playing soundfonts on mt32-pi over udp
my udp.py
#in the config disabled dhcp and set fixed ip
cranked the gain from 0.2 to 0.8, disabled reverb and chorus
(you need to edit the .cfg files for individual soundfonts because those will overide the main config
didn't get rtp working but udp works pretty ok.
midi over wifi can sometimes be a bit wonky but the latency isnt bad.
was hoping to make use of my other midi keyboard in my closet but the notes would get stuck
#!/usr/bin/env python3

sock = socket(AF_INET, SOCK_DGRAM)
midiin = MidiIn()
midiin.open_virtual_port(MIDI_PORT_NAME)
signal(SIGINT, lambda *_: exit(1))

fluidsynth for octamed
you can make midi templates for sunvox and fl studio also
here i use linux mint autostart to run the bash script
and run the render command
- path must be like /home/user/Desktop/ not
~/Desktop/
also drag and drop wont work
it will try to open in celluloid so you must type it out.
#fluidsynth from terminal
fluidsynth -is -p "FluidSynth-GS" -g 0.7 ~/Documents/sf2/GeneralUser-GS.sf2
#bash for autostart
#!/bin/bash
gnome-terminal -- bash -c 'fluidsynth -is -p "FluidSynth-GS" -g 0.7 ~/Documents/sf2/GeneralUser-GS.sf2; exec bash'
#rendering
read -e -p "MIDI file path: " f; f=${f%\"}; f=${f#\"}; fluidsynth -is -p "FluidSynth-GS" -g 0.7 -R 0 -C 0 -F ~/Desktop/"$(basename "$f" .mid)".wav ~/Documents/sf2/GeneralUser-GS.sf2 "$f"; echo "Rendered ~/Desktop/$(basename "$f" .mid).wav"
# using jack instead for cadence to record in audacity
#!/bin/bash
gnome-terminal -- bash -c 'fluidsynth -a jack -m alsa_seq -is -p "FluidSynth-GS" -g 0.7 ~/Documents/sf2/GeneralUser-GS.sf2; exec bash'
# optional monitoring to find port use jack_lsp
jack_connect "FluidSynth-GS:audio_L" "system:playback_1"
jack_connect "FluidSynth-GS:audio_R" "system:playback_2"
# jack and monitoring
#!/bin/bash
gnome-terminal -- bash -c '
fluidsynth -a jack -m alsa_seq -is -p "FluidSynth-GS" -g 0.7 ~/Documents/sf2/GeneralUser-GS.sf2 &
until jack_lsp | grep -q "fluidsynth:left"; do sleep 0.5; done
jack_connect fluidsynth:left system:playback_1
jack_connect fluidsynth:right system:playback_2
wait
exec bash'

samplerbox raspberry pi
program your own screenless rompler. write is disabled on the os making it safe for the sd to be undamaged by unplugging. (idk about the usb with the sounds though? I guess its fine as long as your not in the middle of transferring files)
defle distilled
made a cheatsheet for learning deflemask.
- distilled 53 pages down to 1 front and back.

deflemask
running deflemask on ipad with a logitech k480
the keyboard os modes matter bigtime!
the 2 modes: pc, i.
in I (ios mode)
- cmd h for home, cmd tab for switching apps
in pc mode
- fn left / right = home / end
- fn up / down = pgup pgdown
turn off follow
in the right panel so you can use f7 to play from line
otherwise it keeps going. ESSENTIAL!
- ctrl 123456789 mute channels
- ctrl left / right switch tracks
- ctrl w/e shrink expand
- ctr b = paste and mix (ctrl v is regular paste)
- switching octave is done on screen because /* is numpad only
- note off is tab
- interpolate = ctrl i
- transposing = ctrl f1/f2,f3/f4
work from the top
instead of working from 0-64 top down work horizontally in 16 line chunks to make use of the f5 playback and f7 playbacks for the best of both worlds. copy and paste each 1/4 pattern horizontally and ctrl 123456789 to mute the previous until you complete all four quarters of a pattern to re assemble them.

splitting files for compression for fat32
the way to go would have been to use gparted to format to exfat
fat32 has a 4gb file limitation
// for rar
rar a -r -v3900m archive.rar /path/to/folder/
// for 7zip
7z a -v3900m archive.7z /path/to/folder/
// for zip
zip -r -s 3900m archive.zip /path/to/folder/

sunchop - a chopper for sunvox
sunchop on the sunvox forum eufex made this in pixilang. the demo vid said single sampler pitch mapping is broken but it does work for individual samples for each chop. (eggsem tool in renoise had the same problem) I prefer xrns2mod because then i can get then all self contained in one insturment.
The xrns2mod tool didn't work o. my other computer though so this is when it would come in handy.

best way to make drum kits in subvox
running the cli version in a vm on windows actually is great.
The linux version kept saying my project was too new or something and the renoise tool version would render a blank xm.
My old method of building kits was to use openmpt to create xis out of sfzs made in renoise of groups of samples but the tuning would be off.
the eggsem tool to convert xrns to xm works at getting the pattern data and simple 1 shot insturments but it would mangle pitches on multisampled ones so the xrns2mod cli tool is my new go to method for now.
Deflemask chip tracking strategies
It lacks some important keyboard shortcuts i use all the time in Renoise because of this i've mostly used it as a sound module for ym2612 sounds sampling it and not dealing with the sequencer but i've figured out a few tricks recently to get around that.
no f9-f12 jump 1/4 way through or play from line and return. the play from line in Deflemask just keeps going from where you left off and play pattern always jumps to the start.
my work around is do each 16 ticks on its own channel and mute each one as i move 1/4 across.
this feels similar to using block loop in Renoise.
Another alternative is to use pattern break commands to jump to line zero. it reminds me of clipping in as you climb higher up a wall.

how to move nested wavs
Downloaded some samples that came packed into separate folders. This is annoying because there is only 1 wav in each folder making it a hassle to browse.
heres the fix:
mv -n */*.wav .
then to remove the folders
rmdir */
xm export from renoise
xrns2mod required something called bassmidi library which needed a license to run? tried and gave up this one actually worked for me but the pitches get screwed up in multi samples. still way better than nothing.

sunvox midi automations
in the cc column it starts at 80
so cc1 is actually 81 (also its in hex).
- 91 for reverb is db
- 74 brightness (cutoff)is ca
- 71 timbre (res) is c7
the interpolator tool can quickly create ramps for filter sweeps at a set interval like a tempo synced lfo

chopping samples in sunvox
Easily miss this setting because its hidden in the edit menu under misc as resample new length. set the number of lines to the end of your sample and it will adjust the pitch to play out to that length.
Then you can use the 7 effect to chop on offsets of 8000
snare on 4000 etc..
making kits in sunvox
- add your samples
- connect a multisynth
- options 75 7F
that sets multisynth to c5 and divides output midi note by number of inputs to spread the sounds across the keys. loading sounds it's probably easiest to use milkytracker to create .xi files and save them as meta modules.
