Here's a work in progress, and the crash at the end is one big hint of why I say "in progress."
I made some sounds in OhmSound, saved the presets, and worked with them in the Sequencer. There's 4 step sequencers, and 4 loop sequencers (only the third loop sequencer is doing anything). The loop sequencers have a "chance" control to randomly drop elements from the sequence on each loop. The step sequencers have rules to drop a step every "nth" measure.
So, while the sequences play, I'm playing the synth and using a knob to get some nice filter sweeps going, and controlling the multitap delay with the faders. FUN!
