I've happily streamed 12 or more tracks down to disk through Jack->Ardour. Create a multi-output [dac 1 2 3 4 5 6 7 8...] and wire these up to Ardour inputs in Jack, let Ardour sweat over the disk buffering, it does the job very well indeed. > > I've had some trouble with hardware MIDI stuff before.

When you move a MIDI fader many fader boxes flood the channel with far more CC data than is needed. If you use [change] with a [metro] and [float] you can just catch the start, end and timed (100ms) samples between a fader movement, then interpolate it with [line~] where you need a smooth signal rate control. 2) Use OSC with an external MIDI-OSC bridge, it's just nicer. MIDI interfaces generally uses a UART with one register and interrupt driven I/O, which is primitive compared to OSC on a buffered socket. 3) Never go *through* a GUI slider in Pd. If you must have dual use of mouse and fader box then rig up a "dual gang" display/control. If the data comes from the faderbox then it's routed directly to the control destination through a [float] and the slider is updated periodically. If the data comes from the slider then it updates the [float]. 4) Build a sperate mixer interface in C. I used Qt to hack together a very simple mixer board that sends UDP packets to [netreceive], and that works a treat. > Working around PD's crap GUI is one of the big > challenges.
