Schism Tracker ~ Create High Quality Music


Schism Tracker is a free and open-source reimplementation of Impulse Tracker, a program used to create high quality music without the requirements of specialized, expensive equipment, and with a unique “finger feel” that is difficult to replicate in part. The player is based on a highly modified version of the ModPlug engine, with a number of bugfixes and changes to improve IT playback.

Where Impulse Tracker was limited to i386-based systems running MS-DOS, Schism Tracker runs on almost any platform that SDL supports, and has been successfully built for Windows, Mac OS X, Linux, FreeBSD, OpenBSD, AmigaOS, BeOS, and even Wii. Schism will most likely build on any architecture supported by GCC4 (e.g. alpha, m68k, arm, etc.) but it will probably not be as well-optimized on many systems.

DIN Is Noise ~ Synth Of A 3rd Kind


It forgets history, To not repeat it.
It doesn’t hide analog music hardware, In digital music software.
You had pulse, sine, triangle and sawtooth, And went forth and made electronic music.
Now there is just the Bezier curve. Go make your pulsesinetriangle and sawtooths. Or thisthisthis and this.
TOPLAP Nick thinks this is nothing new, His old men did it in the 60s, Punching numbers into cards. Now you edit waveforms with a GUI, And watch the sound change before your ears.
Has it got ADSR? It’s got DADSARSADS.
Filters? No because Additive not Subtractive.
Modulation? Bezier on Carrier and Modulator. Wolf that Chowning.
Notes? Yes + Infinite microtones in between.
Input? MIDI Keyboard. Computer keyboard.

Pine Player ~ MacOS HQ Up Sampling Max 32bit 768kHz


Pine Player is an exclusive listening digital music player for music lovers who use the OSX operating system. It can play almost all existing digital audio forms such as MP3, FLAC, APE, AAC, M4A, WAV, AIFF, OGG, WMA, DSD, SACD ISO etc. and it also has a strong playing capability for listening to CUE files in the most convenient way.

1.     Maximum 32Bit 768kHz Up Sampling Function

Pine Player supports various kinds of PCM formats, so it can play sound sources from 16 to 32 bit; it can also reproduce clear and abundant sound quality by supporting a maximum of 768kHz.

Pine Player’s unique Over Sampling Filter is a technique that upconverts an ordinary MP3 file into a 32bit, maximum of 768kHz, and high sound quality sound source and sends it to the DAC for it to be played in best performance. Ordinary MP3 files’ sound quality can actually be heard more clearly and plentifully. Obviously, HD audio files such as MQS and DSD can be upconverted to a maximum of 768kHz as well.

2.     Convenient and Strong Playlist & Prevention of Text Cracking

Pine Player has a very convenient playlist because users can save and manage the music they wish to listen to, change the order of the music being played by simply dragging, and express any kind of language or text encoding perfectly because of its flawless decoding function. There is no Korean code cracking.

3.     Cross Fade and Gapless set-up

Cross Fade function, which is a technique that decreases the gap between songs when listening to files on the playlist or overlaps the songs for no gaps at all, can be set into seconds.

4.     Mass Storage of Audio Queue for Real Time Converting

Pine Player prevents damage of sound quality by having a high-powered Audio Queue for processing excessive amount of digital data. Therefore, it takes a considerable amount of memory compared to other music players.

5.     Automatic Isolation of Damaged Sound Sources

Pine Player has an automatic isolation function for damaged sound sources called Vault. If a damaged sound source is detected while playing the music, the music is stopped and taken to the Vault file for isolation. Through this convenient function, users can easily figure out which sound source is damaged and restore it.

Even with all these functions, Pine Player is a free app. Moreover, there are not any marketing or advertising material. Especially, no information including personal ones are sent to the outside or the Internet.
