Hi,
I think there's a way to quite intuitively support continuous pitch bends or slides between notes by building in support for the Continuum's portamento mode. It allows you to setup an interval in between which notes aren't re-triggered. Instead, a smooth pitch transition is implemented, based on the relative pressure of two notes. The speed of the pressure change and the relative difference allow you to change how the pitch transition behaves. For instance, if you apply the same pressure on two notes, the pitch will be in the middle. I find that it allows you to very intuitively control slides in any directly and based on your hearing are able to control intermediate notes. As long as you press any of the keys that are within the interval, the portamento mode continues, so you can create guitar-like whammy bar sounds.

On the Eigenharp, apart from the pitch bends, this could maybe also be used with the upcoming 'combined key press' feature that was discussed many months ago (to increase the range of the Pico in monophonic mode). This could but a keygroup into portamento mode when a predefined key is pressed at the same time.
What do you think?
