I might add that all of the synths and Hydrogen were running two LADSPA
effects as well. Seeing it written down I would say now, I wish I had more
CPU than the AMD Athlon64 X2 5400+(AM2 2.8G 512KBx2 65W) with 4 GB of RAM
that I am using, if anything so far. There is audio coming and going through
the FTPro.
