IIRC, Rapture 1.0 had a handful of Elements 'outside' the Program structure, and the default file location changed in RP 1.1. I'm of the opinion that the Element component is the most underutilized and misunderstood level of that synth's hierarchy. It's perfect for a Lego-like approach (as an expansion pack concept).
For the U120 contribution, I thought it would be cool to emulate the Filter and Tremolo Sequences in the AdrenaLinn III stompbox pedal. I spent an inordinate amount of time on exact matching. The 'Arpeggiator' Sequences were supposed to be included as well. But I just couldn't force Rapture's resonant delays to a fine enough resolution for producing 'pitched' sequences.
My intent with the U120 Elements was to add the ability to mix & match / drag & drop Elements, in Program creation. The Elements themselves are basic square .wavs, but with the appropriate filter settings, envelopes, and sequencers for emulating the baked-in ADR III presets. Many of these Elements are complementary building blocks.
Warning: Set the Limiter first.
