[Discuss-gnuradio] Sync block or general block?

Hi to all,

I am trying to create an OOT block. There are 6 inputs which are float32 single parameters. There are 3 outputs. 2 of them are again single variable and float32. The last output is a 33x1 vector with float32 entries. 

Which block type should I use and how should be the forecast function?

Best,

Ali
