intuos3 vs bamboo

[Michael Palace]

Just a thought about having 128 steps of MIDI data as a limitation..

Since this discrete steps are most notable when slowly changing a filter or
oscillator pitch, when used in some software like PD or MAX, could a running
average be used or something related to the slope change of the values be
used extrapoliate values of 1-512 in the software code.  Slower changes can
estimate intermediate values, while fast changes it is not necessary.
Storing the previous cc# value should not be an issue in the software.

Not sure if this made sense.

we actually just got a bamboo, it's an excellent tablet. amazon has a
good price on the medium, which is really what you need for good working
space.

i'd definitely recommend it if you're already considering a wacom and
just want a good price point. a professional story-boarder/designer
friend of mine uses the intuos but recommends the bamboo any day.

the mouse isn't especially useful, but it's really cool surfing the web
with a pen... i actually like the paradigm of "pull the page down"
instead of "scrollbar", effectively a reverse of the direction you move
your hand. strangely enough it feels more natural.

I have some experience in using both a Wacom Bamboo tablet and a much more expensive, larger tablet belonging to a graphic designer friend, and while both work quite well with the CNMAT external in Max, the pressure sensitivity of the Bamboo is one thing that lets it down. Although there are indeed 512 levels of pressure sensing, in practice these seem quite inconsistent. The surface of the tablet is also a little scratchy for my liking, certainly compared to the more expensive model. Despite these niggles, because of its price (about £70-80 here in the UK) an portability, the Bamboo remains quite an attractive proposition.

No, it makes perfect sense, and actually that's what people do in
their soft- or hardware. You often interpolate or filter or otherwise
map your input data to something better suited for your application.
However you also need to take care, because for example filtering with
a running sum or so adds a bit of latency.

If you use Pd, there's the "mapping" library which has lots of mapping
related objects, also some complex ones, for example to map the speed
of drawing circles on a gfx tablet to some value in your patch.

the way i work with filters in my patches is to use a timer to measure
the amount of time between the last number sent and the next number, and
use this timer to set the interpolation time.

so to move very slow through the numbers i turn the knob slowly -
sending out eg 29, and 2 seconds later, 30, will interpolate between 29
and 30 over 2.2 seconds. to jump i turn the knob quickly - or at least,
make sure that several values come through in a short period of time.

i could perhaps make it nicer by doing some kind of quadratic
interpolation rather than linear interpolation, but this existing system
works well enough in practise.
