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

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"

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.

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

xrns2mod tool

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

eggsemm

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..

yt video on choppage

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.
