The Soundtracker
How does the St-01 amiga samples originally sound?

The trackers are typical affordable (or free) musical sequencers used by various system.

The concept was born in 1987 with the ULTIMATE SOUNDTRACKER (EAS Computer Technik) written by Karsten Obarski for the computer . Commodore Amiga uses the 4 PCM samples voices generated by PAULA audio chip.

editWhat's a MUSIC TRACKER? The original tracker was based on simple sequencers using internal samples (not Midi samplers). Each samples was entered as a note (pitch samples) into different channels lined up on columns patterns.


edit AMIGA TRACKER - The samples can be usually edited (eg.volume and EG for early trackers) depending on the software, then the song can be saved on various "module" format like .mod, IT, S3M [...]

editMUSIC TRACKER Influence Right after the Ultimate Sountracker release, many freeware / shareware clones appeared and music trackers began to be appreciated amongst DEMO SCENE people, not to mention some commercial blockbuster games. The tracker concept is born with the Amiga then evolved and spread to both modern platforms (e.g PC RENOISE) and even to older computers (C64, spectrum, MSX, Atari St). Today tracker softwares handle much more tracks, feature high quality samples, filtering, VST effects, virtual instruments.

editThe tracker sound collection ST-XX In order to reduce module file dimension and simplify songs swaps, many modules did not include the most common samples since these were on available on a standard free sound library collections called "ST-" followed by a number indicating the disk number (officially from ST-01 to ST-116).


edit Originally most of these ST-XX samples were recorded from synthesizers or drum machines from this era, but seldom reported the original recorded source (copyright?) but some short "hints":

e.g.D50 heaven-> staccato heaven


edit ST-01 DISK The first disk ST-01 was probably the most popular and used as it contains some very classic sound you heard hundreds of time on classic Amiga songs. According to both web indications, name's linkenes, I managed to record some original synth sound sources - not an easy task since Amiga ST-01 short samples were sampled at 8/11 kHz at low 8 bits resolutions with many audio artefacts.


Most of the st-01 samples were recorded from 3 common synthesizers:

- Roland D-50

- Yamaha Dx21 / 27 / 100

- Casio Cz101 / 1000

Following a full 44 kHz 24 bits STEREO recording from original machines, this will be updated when new sounds (for suggestions drop me a edit LINE).

ST-01 SAMPLES FROM ROLAND D50 A classic digital synthesizer from 1987 based on LA synthesis, also well-known to retrogamers for the Roland MT32 module.

edit ST-01 SAMPLES FROM YAMAHA DX-TX 4OP line. Many Amiga samples come also from 4 OP FM synthesizers developed by Yamaha. The 4 OP FM machines were basically buget version of more DX7 traditional 6 OP (6 sinewave oscilaltors) with simpler sound and less algorithms. The 4 operators family are based on similar IC YM chip / DAC compatible between them, consequently it is actually totally impossible to tell the specific the true original module or synthesizer recorderd on the Amiga samples.

Most common 4 OP FM machines are:
- 4OP with standard sinewave: DX21 - DX27 - DX100
- 4OP with sinewave + harmonic variations: TX81Z - DX11.
Later 4 OP models c.a 1988 (V50- TQ5 - WT11 - YS100/200) could not be featured into the ULTIMATE SOUNDTRACKER since it has been released in 1987.
HINT: FM synthesis has been also implemented on famous PC soundcards ADLIB/SOUNDBLASTER with the OPL chip.

4 op synth edit According to the ST-01 likeness names, it is mostly probable that the sound sets comes from DX21 presets.
