73-75.com Homebuilt demos (preamp feedback/delay), July 2022 by user510847274 published on 2022-07-28T15:36:59Z Recordings of self-playing unattended patches on the 73-75.com Homebuilt Serge, all of which utilise the preamp input to create a tape delay -style feedback loop (the output of the soundcard is routed back into the Serge thru the preamp, and the latency from the recording software adds a slight delay to the signal). The individual recordings (randomly mixed together in a regularly crossfading overlapping pattern, so that there are never more than two recordings playing at the same time) were made straight to disk with no overdubs, no external controllers or sequencers, and no outboard effects apart from some EQ from a Soundcraft Notepad 124.
