Hello!
I've been making some progress on the native D audio front:
https://github.com/clinei/daud/tree/28ac042a16ae6785605a9a501b5f867c8f962055
It's a continuous waveform generator, currently outputting a saw
wave that changes pitch every 1K frames.
I have a slight problem, however.
Due to the frequency changing in the middle of a wave, I have to
patch the new waveform together with the last, which I've done
with `countUntil` at daud/gen.d:211 (I don't need to call
popFrontN because the range is a reference type).
However, when calling `RepeatingGenerator.frequency`, the value
of `_repeat.front` is not the value of the last frame.
app.d:61 is a temporary hack.
How could I get the value currently passed through `cont` from
`_repeat`?
