OK, this is a bit of a saga.
I looked at the theme, and thought of space ... and earth, which is also in view. This brought to mind the phrase: "Spaceship Earth" and this planet's limitations which, in a small way, are echoed in the weaknesses of spacefaring technology - and the limited life of our biosphere is echoed by the weaknesses of a breaking space vessel.
This led me to think of the experience of inhabiting a breaking space vessel, with air slowly bleeding out, and waiting for the end.
I did everything in the box on my Akai Professional Force.
Every track was a synth plugin.
The first one was the arp, for which I used the Odyssey plugin. I set it going, with a few tweaks. I used a macro to address its volume parameter on a free-running LFO, and also set note probability and ratcheting on it to give it shadows of variability. I used it to represent the backdrop of technology, running along on its own. I used a sidechain compressor to deliberately bury it behind other sounds, as being neglected when other things take attention.
The second one was the broken machinery echoing sound effect, for which I used a Hype plugin pluck, pushed through the Granulator effect to give it that echoing, rattling sound. I created a 32 measure loop, which I randomly, sparsely populated with hits (thanks, Akai) and then put a low probability on to make it a very irregular event.
The third one was a dark string pad intended to form a backgrop. Just the Hype plugin again, somewhat tweaked.
The fourth one was the electric piano, for which I used the Electric plugin, tweaking the details of the sound but leaving it quite dry because I wanted to use it to present the inner life of the observer; near and clear, over the wet backdrop of the other things representing the vastness of space.
The fifth one was the high string/choir sound from the Hype plugin, intended as a sort of rough counterpoint to the melody lines. It occupies a higher part of the spectrum and got plenty of reverb.
The sixth, final one was the gliding, modulating lead which I configured a bit to present the vicissitudes of the situation itself rather than the personal experience, or the spacecraft. It's a mono Hype plugin, which I tweaked for a little extra flavour. The modulation on it linked to the modwheel for raising or burying it in the mix with the filter cutoff.
The song itself I laid down in a single sequence rather than a series of loops, extending it to give me linear sequencing. The arp and the sound effects I used looping to save time, but the other four tracks all had full length clips. I recorded them live with my KORG MicroKEY61 so as to get a more human feel for those tracks, leaving them unquantised.
The song has three movements, starting with the arp and sound effects, and introducing the dark pad and electric piano to give the initial statement. Those with sharp rhythmic ears will hear that I had the piano using a 7/4 motif, while the pads try to keep a straight rhythm. This is intentional, structured to give rise to a sense of imbalance, of discomfort, relating to the concept of the piece. It is slow paced, because this is about slow decay.
The second movement de-emphasises the electric piano and pulls in the mono lead, bringing in a new motif that states the situation more clearly. It is a different motif from the electric piano's original statement but compatible with it. At the same time the high choir patch comes in, lending an auditory poignancy to the soundscape.
The third movement brings them all together, before fading out.
I used Audacity to do a bit of final compression and normalisation, I think that the levels and loudness should be OK.
