No I meant I last tried LADSP the last time around the time
af_scaletempo was added to MPlayer.

No difference there I think. You could add it though, there is already a
AF_CONTROL_SCALETEMPO_AMOUNT, you'd just have to hack it into the
property system and use
> af_control_any_rev(mpctx->sh_audio->afilter, AF_CONTROL_SCALETEMPO_AMOUNT | AF_CONTROL_SET, &variable)
to set the current value and
> af_control_any_rev(mpctx->sh_audio->afilter, AF_CONTROL_SCALETEMPO_AMOUNT | AF_CONTROL_GET, &variable)
to get the current value.
