ZX81 is a British monochrome computer as big as an adult man's hand-palm. It has touch-sense keyboard and 1Kb of RAM only and it's been released in 1981 (American version is Timex 1000 and Timex 1500). 
It had a modular construction, so people weren't forced to buy all the hardware in one machine, if they didn't need it. So - if anybody required additional RAM, he could buy 16Kb RamPack or more. 
If somebody needed sound - he was able to buy a ZonX sound-module (with YM/AY chip inside). 

Finally we decided it's not enough for us. ;) ;) ZonXes are still being produced by various guys. And now - one machine is interesting for our porpose: Mr-X, because it is a through-out device - more interfaces can be connected to it. So - we decided to connect two sound-modules to ZX81 (one of them is on different ports than another) to obtain 6 channels of sound. 
And... IT'S ALIVE!!!!!! ;) Yes - You can here listen to  6-channels music composed on real ZX81 32Kb with two YM/AY interfaces (ZXpand-AY and Mr-X). Also I recorded the music from real ZX81 hardware. 

To compose the songs I used Andy Rea's "ZX81 SoundTracker" (first I made one half of every song, then the second one, because the SoundTracker for ZX81 can support only one AY chip - 3 channels). 
Then I recorded them from the same ZX81 with ZXpand-AY and Mr-X modules (using TurboSound Player). 

Thanx go to Andy Rea for the software (ZX81 SoundTracker, TurboSound Player), also to ZX81 hardware developers: SirMorris (ZXpand and ZXpand-AY) and to Sascha2000 (Mr-X).

Yerzmyey - Break Space

This is really a proof of concept, I made for the idea of playing simultaneously two ZX Spectrum computers, where one is playing chiptune music and the second one is playing digital music (6 channels in total).
I was wondering if it keeps tempo properly - and it appeared it works OK. 
I don't know if it sounds very well, but at least sounds kind of interesting, I'd say. 

One Spectrum is playing a chiptune part from ZX SoundTracker 1.1. 
The second Spectrum is playing a 3-channels 4-bit digi-music from SampleTracker 2.1.

ZX Spectrum is a computer from 1982 year. 
CPU speed: 3,5 Mhz. 
RAM: 48Kb.

AY-interface contains General Instrument AY-3-8910 chip or ym2149 chip (depending on model. A difference in sound is minimal).

Yerzmyey - Proof of concept

A chiptune made on ATARI 520ST (YM chip).
Soft: MusicMon. 
***Recorded from real hardware.***

The song comes from my album "Chiptunes" (October 2014) downloadable from here: http://yerzmyey.i-demo.pl/

After 17 years of having ATARI ST, this actually is my very first chiptune 
for the machine. :) 

Thx to Ato and all guyz from 
http://atari-forum.com/

The song took the 2nd place in the SillyVenture 2012 ATARI party, on Atari ST/E chiptune music compo. 

Yerzmyey - Wake up!

This is the final version of my very first song for the British computer SAM Coupe ("Spectrum Advanced Machine").

The song has been made for its Philips SAA soundchip (6 channels). It took the 2nd place on the AAA-Compo 2013 on-line party.

Software: E-Tracker.

Works also on ZX Spectrum with ZXM-SoundCard.

Enjoy. 

Yerzmyey - Arcane Zone (Part 2)

***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............................
