Some time back I posted re: trying to get parameter modulation into AM.
Since then I've experimented with using Reaper to stream midi modulation into AM. Usable, but not very intuitive.
But recently I discovered Nodal:
It's basically a midi sequencer that uses network diagrams to create generative music. I like the fact that you can easily create and visualise non equal phrase lengths. It's quite simple with few features and still a little wobbly at times, but I've really enjoyed using it.
Last night I created a few experiments sending control messages to AM using polyrythmic patterns. I could probably have created all of this in AM, however I found it much easier to visualise in Nodal.
And like AM it's Australian :-)
