After watching the RedMeansRecording and then doing the walk-thru from MoltenMusicTech I had a go at creating a Krell Patch on the eurorack.
Not strictly self-playing as I'm shooting the Input of the Befaco VC ADSR a trigger from Mutable Instruments Marbles, Marbles is mainly used as a modulation source. The Gate-out of the Sustain stage on the Befaco Triggers the Sample & Hold and changes the Oscillator pitch. Lots of modulation from Ochd, Clep Diaz, Marbles & the 2hp RND.
You can ignore all the wires, I have 2 patches going on here, and I ease in a patch built around the Error Instruments Indian Resonator about half way through, the Indian Resonator works great when you combine it with a Sine wave and stick it through a Wavefolder so there are 2 parts that come from that.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
