@TomWhitwell what a fantastic album and concept!
I’ve been thinking about doing something similar when I have some downtime in a couple of weeks. I’m planning to record a tune an evening over a couple of days, but record straight to a cheap cassette 4 track.
One of the things I am looking forward to trying is recording a rhythmical track and then playing it back through an envelope follower/gate to generate a crude sync signal for overdubbing another track on it.
@Oootini great idea, I’ve done something similar in pure data before. I’d imagine it should be pretty straightforward to generate some clicks (literally just a max value followed by zero) and save to a wav file. Or even save the numbers to a text file and open it as a raw soundfile in audacity.
