Just finished making a very small gesture synthesis example in Konilo! [0]
The Gesture sequence is written in uxntal, metaprogrammed from Konilo. The synthesis patch makes underlying calls to the sndkit API to build up a sound. It has a gesture-synthesizer-generator (GSG) which reads from the "hello" uxn subroutine created above and synthesizes a gesture controlling frequency.
I figured out how to add my own sigils in Konilo, so now something like "%0.5" will push a constant value of 0.5 to the sndkit stack (I send it as a string, then internally it gets converted to a float value). This allows me to pass around floating point params even though konilo doesn't support them.
