The touch-tones are a good idea, and very easy and accurate to decode
using a common touch-tone decoder chip which takes a normal audio input
and gives a 4-bit output. You could hook the chip up to a BASIC Stamp
and, with a bit of programming, communicate with MAX using the serial
object. Total cost should be about $50 US.

It is also very possible to decode touch-tones in software. I have a
copy of a HyperCard XCMD that does this, with source code. An
experienced MAX C programmer could create a touch-tone decoder object -
which would probably be a very useful thing. I wish I had one...

I am also interested in finding some good pressure switches. The Icube folks
make some that are fairly good, but expensive. ($30/each I think) There's a
company called "Tapeswitch" that I have run across which purports to have
good stuff but I've yet to receive their catalog. Building my own out of
materials works fine but is expensive. Building my own out of cheap radio
shack-type piezo materials is okay, but requires a lot of filtering to get a
useful signal. Does anyone else have experience here?

For your analog I/O you probably want to check out the ICube, in addition to
the Pavo boxes you mention. Also, I've just started using various pieces of
X10 network to do analog I/O (at very low bandwidth). More about that as I
learn it since I know others have expressed interest before.

Relevant URLs (I think):

Infusion Systems, the ICube makers -

Subject: Max, OS 8, and the MIDI Manager

I have discovered a problem with the combination of using Overdrive
in Max with the MIDI Manager (*without* OMS) with Mac OS 8. The
symptoms are spurious stack overflow messages. For the moment
I would suggest not using this combination, which is probably
pretty rare since the MIDI Manager's Apple MIDI Driver doesn't
seem to load under OS 8, so you need to use OMS to have any MIDI
in or out.
