Yerzmyey - Deadly Labyrinth of Lord Xyrx

One chiptune made on two classic 8-bit machines from 1982: Spectrum 48 & Commodore 64. :) 
Composed by YERZMYEY (ZX48) & RIO (C64).
Chip editors used: SoundTracker on ZX and DMC on C=. 
Mixed by Rio Rattenrudel. 

Made in 2010.

A 'funk' chiptune with a slow intro. Made in 2016. ZX Spectrum 48K with AY-interface was my instrument here. 
Some complex synthesis has been used to avoid the usual boring square-wave of AY. The problem with those advanced synths is - literally all notes have to be tuned manually to a proper key/pitch. So You can imagine it's kind of tedious. ;)

Well, theoretically ZX Spectrum (and other computers with AY chip inside) have no sampler - only a digital synthesizer. 
But when the AY is being linked to any CPU chip (Z80 in my case) - it can actually be used as a sampler too. 
With the Z80 power, ZX Spectrum 48K can play 3 channels of digital music through the AY-interface, with 4-bit quality  (btw, it can do it via ULA too, but in 1-bit quality). The SampleTracker software has no volume commands, so - to achieve delays  :) - I have to make the same sample twice: the louder one, and the more silent one, heheh. That takes RAM away, of course, which is crap because I have only 48K of RAM on ZX Spectrum ;) (even less, actually, hehhe). 
Italo-disco for life. :)

Yerzmyey - Jophar Vorin of Laxaria

The music has been made for the NES / FamiCom / Pegasus game-consoles. 

They contains Ricoh 2A03 soundchip with 5 channels of sound: 
- two pulse channels,
- one triangle channel, 
- one noise channel and 
- one DPCM (sample) channel.

This is my very first song for the NES. :)

Yerzmyey - The Lady of Mars

Heyyyyyyy!!!!!! :) :) :) 
This is my new song for the NES / FamiCom / Pegasus platform.
As usual it's standard 5-channels song for the stock machine with Ricoh 2A03 chip only.

Yerzmyey - Return to Taured

Hi.
This time some older song, made in 2009. 
It's ZX Spectrum 48K with AY-interface. :) 
Software - ZX SoundTracker 1.1.
Enoy. :)

Yerzmyey - Yerzmix part 5

Hi. It's a 6-channels song for one SID chip (6581). 
Composed in 2019 on The C64 Mini and recorded from it. 

The song is kind of a test I made to check out two things: 
- is the Polyanna tracker for C64 any good? Yes. It can play 8 channels or 6 channels on one SID chip, on a regular Commodore 64 (the old SID is required). 
- is The C64 Mini computer any good? Yes. Most of the stuff - including sound - works much better that I expected. 

As for the Polyanna tracker by Aleksi Eeben - here are a few words from the programmer: 

"
Polyanna is a 8-channel music editor for Commodore 64. It plays 3 regular SID channels together with 5 emulated SID channels on a stock machine. Old SID chip (6581) is required. The mixer is based on Sid Vicious, a SID emulator I wrote for VIC 20 in 2006. For optimal performance the emulated channels in Polyanna are optimized for pulse waveform only. Pulse width
modulation and envelopes are of course supported, although they're rough. Don't expect too much! :) There is also an optional 6-channel mode with improved sound quality:
- 8 channels: 3 regular SID + 5 emulated channels @4.4kHz
- 6 channels: 3 regular SID + 3 emulated channels @7.7kHz
"

As for The C64 Mini, I like the machine; it's good for games; it's also kind of good for making stuff: although the disk-drive speed is more/less the same like on the original C64 (You can speed it up a bit but sometimes it may cause problems with loading, so anyway I use the standard floppy speed only) - however here You have also 4 slots for snapshots, for each diskette. Instant saving / loading the song while composing is a very nice & useful feature. Really comfortable. When You finished composing - You can normally save the final song into the diskette (the *.d64 file) and move it anywhere - into an emulator, into a real diskdrive and the original C64 - and so on. 

So anyway - some more 'crunchy' sound sometimes - isn't any faulty procedure of the C64 Mini SID - Aleksi says it sounds the same way on the original C64 (and it doesn't work at all on the C64 with a new SID, we checked it out already). 
Also - it might sound even better but I made the song in a wrong way - being corrected by Aleksi too late :) - he said that it's more reasonable to use low sounds on the emulated channels and high pitch sounds on the hardware channels. Which I might figure out by myself if I only took this effort to read the instruction, haha (the "7.7kHz" fragment might give me a clue ;-) ). 

You can notice the problems with keepin' tempo too, hehe. But this sound-engine is really a killer for the Commodore, hehe. The computer does what it can. 

I dedicated this song to my Kate because she is a mathematician by penchant - and a programmer by profession, so she can appreciate how tired the 986 Hz processor is, playing this stuff (yes, I use PAL). :-P
Also, she likes 80s style of music. :-)

Yerzmyey - Kate (The C64 Mini song)

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............................
