The problem is rendering "faster than realtime", rendering "slower than
realtime" is perfectly possible, I do it often.
Rendering faster than realtime isn't quite as simple as upsampling, you
have to scale all clocks to match (like [metro], [delay], etc).
Shouldn't be too difficult to hack Pd to work properly in this
situation, as long as everything timing-centric adds events to the
scheduler through the same mechanism.
