I´m having trouble to make PureData(Pd) to work at low latency in Ubuntu Studio 12.04.
I get Pd and Jack to work together with my Audio Interface (Alesis IO4) but only at a frames/Period of 1024, which means a latency of 45.2 ms.
As soon as I try to lower the Frames/period to lower the latency, I get an Audio I/O error from Pd.
I tried to mess around with the oder parameters, but the only one who appears to affect Pd (and the latency) is the Frames/Period.
I also tried to use the configuration explained here: https://help.ubuntu.com/community/HowToJACKConfiguration , but it doesn´t work either. I really need to get the lowest latency possible, because I work with live instruments and proccesing.
