The Spark In Me

Vivacity

This is a dubstep/chipmusic song made for the "Weekly Treats" series: 
http://weeklytreats.net/album/29-yerzmyey-gasman

Here is a video from the concert version of the song: 
https://www.youtube.com/watch?v=feOqOBTui5g
with live drums and synths. 

Anyway, this song has been made on a pure ATARI TT, a machine released in 1990, with 4Mb of RAM, 8-bit sound quality, with 2 hardware digi-channels only.
The trick is - HexTracker gives 16 channels, using the Atari's 32Mhz Motorola CPU.
(Can make more but with a substantial sound quality reduction).

This song is a MOD format and has all its limitations (8 bit samples, only 64Kb for a sample, only 31 samples in the module, octaves limitation) but the only difference - are those 16 channels in the MOD (software mixing).

Recorded from real hardware (that originally has only 2 digi-channels, haha).

Yerzmyey - Trip to Japan

I've just finished a small test of Amiga1200 working with MIDI. 
Hardware: Yamaha QY70 + Amiga 1200 (MIDI).
Software: OctaMED 4.00.

Amiga 1200 - a computer launched in 1992. 14Mhz of Motorola CPU on-board. Mine has 10Mb of RAM. The song surely would work on standard 2Mb, without problems. 

Yamaha QY70 has been released in 1997. It's a very small synthesizer with sequencer (but can also work in MIDI mode), similar in its look to Atari Lynx handheld game-console. 
Sound generation method: AWM2.

OctaMED 4.00 - the series generally has been closed in 1992 (later the program became freeware). 
You can use 16 channels here, in the MIDI mode, however it still works as a tracker, so - for example - You cannot put a chord into one channel: You have to use 3 separate channels to make the chord.

Virgill - Transient

I got asked in 2018 by a team of really great people if I wanted to create sort of a boss song to be included on a vinyl-record for their upcoming Sci-Fi tabletop roleplaying game.
