I finally put together something interesting in the iPad app Drambo – a couple of months ago. I've been using it to tinker with software versions of Mutable Instruments Eurorack modules. Since the hardware modules are digital, I presume that the output of the Spectrum set of AUv3 plugins is similar to the real thing. These run as plugins in Drambo, which I'm also using as a sequencer and mixer.
I do sense that there's something lost in translation between physical knobs and an array of GUI controls. For now, though, I'm happy using Spectrum to discover the sounds Plaits and Rings can make. This uses the Rings algorithms to create drummy and bell-like sounds.
I made several takes of this patch, and I was never satisfied with one. That was a month ago, and I've started tinkering with a new Drambo patch. What I've uploaded is the last recording I made a month ago. Some passages were too quiet, so I ran the audio through Universal Audio's LA-2A compressor.
