Hello, If speed is not a problem, you can send 2 Midi controleur for each external input of your controller. While sending the 7 bits on one controller and 7 other bit on a diferent controler, there is no problem for sending 14 bits messages. This is slow.
If speed is a problem, UDP is, for me, a good solution. I have build a new interfaces for Max, and now for Pd, using standard UDP
object.
UDP is more than 2 time faster with 16 bits than a 7 bit Midi link.

hi david,
on my site you can find a input box that plugs into the parport of a pc. its a cheap (in means of $) design, and has 10 bit resolution (or 12 with a different ad chip) up to 88 inputs are possible (in step of 11). speed is quite fast, a few msecs for all ports, faster than midi anyway. of course you have to build it your own, but its really easy ;)
the "driver" object currently only exists for jmax, but should be really easy to make it pd on either linux or windows.
see the electronics part of my site for that. pricelist for digikey is also there (but maybe outdated) : http://mamalala.de/files/electronic.html
i know of at least 5 people who have build a complete box and use them in a "production enviroment", but a lot more have build them (tough i dont know how big and for what use)
greets,
chris

What do people use for controller input into Pd? I'm geared towards building a MIDI slider box (ucapps.de) but it occurred to me that it really would be nice to have a finer grain input than 7-bit.
I built a controller that uses the joystick port (spacetaxi.de) but the jitter is a little too much to deal with (unless anyone has a jitter-filter patch they could send me).
Are there any options through the serial port? What are my options for finer-grain controller input?
