"scratch buffers are by definition scratch and their contents are undefined at all times" "silent buffers are by definition all-zero and should not be used for real data" But track & route were using those for actual data; plugins (which may run in the same thread and may get the same buffers) use them for scratch thereby overwriting real data. In particular get_silent_buffers() (used by LadspaPlugin::connect_and_run) clears the buffer which can holds real data: e.g. via Route::passthru_silence() -> plugin1 -> plugin2 (clears output of plugin1)
