I've also got a Bamboo (old black version with blue LEDs) and I use it instead of a mouse for everything almost all of the time.  Works very well with Pianoteq too.  The Wacom tablets have sub-pixel accuracy (ie. they can detect movement much finer than a pixel), so they're as accurate as mice, and faster to use (if you can get used to the pen way of working) as you can instantly move the cursor anywhere.

The only downside to them is that when you press the pen (and also when you let it go), you inevitably end up moving the cursor a couple of pixels.  This is fine in most programs, but some are not coded to ignore this minor movement.  For example, some layout style programs, where you end up moving objects that you're just trying to click on with the pen (something the developers could fix, but they often don't use tablets so they never notice it, and if you try to explain it, they often don't care).  It's worse on my system though as I use 4 monitors, so the small A6 tablet is covering a lot of pixels.

But anyway, even cheap tablets like the Bamboo rule and can replace mice for (almost) everything.

I have a Bamboo Pen & Touch and just gave it a try with Pianoteq.  I find it perfectly usable (the touch part - didn't bother trying the pen!)

The model I have has 4 buttons on the edge, two of which are assigned to left and right mouse buttons.  I don't recall if "touch-only" tablets all have these buttons.  I would highly recommend getting a model with assignable buttons: it's much easier to be able to point (touch) with one finger and click the mouse button as required with another finger. 

Thanks to Pianoteq's clever dual granularities (mousing left and right on a slider changes the values "faster" while mousing up and down will fine-tune the value), it's no problem setting which ever value you wish using the touch pad.

HTH and good luck!

But I worry about being to accurately pull down sliders and click on some of the smaller buttons in PianoTeq. (Using fingers, not a pen as on some Wacom slates.)

Does anyone have any experience in controlling PianoTeq with one of these touchpads? Thanks for any insights or suggestions.
