I saw Vizil try this a few days ago (https://www.audiotool.com/track/7kjok0s2/) and wanted to give it a go. It also reminded me of when Inavon blew my mind doing a challenge like this with a kick and then with a hi-hat (https://www.audiotool.com/track/ew_that_kick_drum/)
I turned the FS.Tone_03 oneshot into this pad, check the assets for the oneshot. I also bounced the timeline so I could slow down the pad using the machiniste, hence the hidden sample. The single Pulv in the snapshot is just there for it's audio-in feature so I could use it's envelope control to give the pad some plucks, non of the oscillators are active.
I don't use Rassel often but in this challenge it was indispensable.
In case you are wondering, there are 4 instances of the one-shot that you can hear and then at the end there is also the bounced timeline sample.
