Oh what fun - Droneo 1.2.2 is in the app store, ready do drone in the background under 4.x!
also:
- Insects have more interesting envelopes
- A new type of Timbre class, the "Consorts", puts different timbres on each reed.
- other minor fixes and interface changes.

I'm thinking of taking all my Drone technology and re-imagining the interface to run the iPad, rather than updating Droneo and Srutibox.
It'd use the tone spiral as its main interface, and something else to control the "churn" features.
