For day 3 of my little coding spree, I've got an engine with 2x3=6 square wave channels for you. Sound is a little more rough than in engines of the same type with less channels, but well, that's what happens if you push things. This engine also has variable pulse widths, although less fine-grained than normally.

I like old microprocessors and ancient deities.

***ALL MY SONGS ARE HERE:*** https://yerzmyey.bandcamp.com/ !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I started to make chiptunes on ZX Spectrum computer, in 1989. ZX Spectrum 48K has 1-bit sound by default, but one can also connect an AY-interface to the machine (existing since its very beginning in 1982 and even earlier because first AY-interfaces have been built for ZX81 computer - 1981).

Anyway - then Spectrum48 has the same sound-abilities what Spectrum128, Amstrad CPC, Atari ST or MSX have (they use the same chip standard: AY/YM). It means 4-bit sound, 3 channels + white noise generator, square wave and several 'buzzers'. Or - instead of it - I can use 3 channels of 4-bit digital sound with the AY, but then I have to fit all samples in 48Kb of RAM. :)

In case of chip-music, as "standard capabilities" I understand AY/YM working in 50hz (Atari ST can use this chip with 200hz of speed which gives the Atarians better audio effects due to their more powerful CPU - 16-bit, 8MHz. Cry cry!!).
So that's my weapon of choice: ZX Spectrum 48K with AY-interface. 

For making chiptunes I use ZX Spectrum's Sound-Tracker 1.1 and for digital MOD-like music I use SampleTracker 2.0 and 2.1.

In 1994 I started to make music also for Amiga 500 (MOD / MED files) on OctaMED, but they were 4 channels traxx mostly - in 99%. :) We made only several 8 channels tracks on OctaMED but it was pretty hard task for old good A500, so usually I stick with 4ch. :)

In 2002 I founded AY-RIDERS band. We play chiptunes on our Spectrums (48K, 128K and higher models). AY-RIDERS' music can be found here: http://ay-riders.speccy.cz/ (My own music You can find here: http://yerzmyey.i-demo.pl/ ).

Some time later I started to make more music for Atari ST and STe (mostly digital, but also some chiptunes).
That's how the YM-DIGITAL band appeared in 2010: http://ym-digital.i-demo.pl/ - there are 2 albums for all enthusiasts of ym2149 chip and digital oldschool music.

In 2012 I bought an Amiga 1200 and was able to start making full 8-channels digital songs for the platform (with independent volumes). That's how the "RetroBeat" album appeared, for all fans of Amiga, and also for fans of retro-computer-music.

From time to time I make songs for Atari Falcon 030 (10 channels of digital music, on DHS-Tracker). 

In 2015 I bought a British microcomputer Raspberry Pi 2 (smaller than the human hand-palm :) ), and I make some music on it, too. 

So, in short, my software/hardware usually are: 
SoundTracker on ZX81;
E-Tracker on SAM Coupe computer (Spectrum Advanced Machine);
MusicMon on ATARI 520ST;
DigiComposer on ATARI 520ST;
ProTracker on ATARI 520 ST;
Hex-Tracker on ATARI 520ST;
Octalyser on ATARI 1040 STE;
OctaMED on AMIGA 500;
DigiBooster on AMIGA 1200;
Digital Home Studio (DHS-Tracker) on ATARI Falcon 030
MilkyTracker on Raspberry Pi
.............and many others............................

I tend to dump random musical ideas here. Also now a member of Cool and New Music Team??? Hope you enjoy!

I often start things and never finish them, so quite a few previews here will be abandoned. Most of them have been moved to my secondary account, so you can check that out if you want to.

Hello

I'm Tufty

I've been interested in making music on the ZX Spectrum and Atari ST since the mid 1980s.

During the late 1980s and early 1990s I made quite a few tunes on the Atari ST using the Quartet music package and also released quite a few demos into the public domain.

These days I'm very much enjoying a musical renaissance making 1-bit music using vintage computers as instruments. 

I have released an album called '1-bit Mechanistic' on bandcamp and am working on other retro projects.

Btw, I added the 'Atari' to my handle to try and distinguish myself from the other tuftys (including that darn famous squirrel) on the internet these days :)
