Please visit the new H-Pi Prototypes webpage

This new webpage gives details on new product
developments and practical design features which
may give you some good ideas for discussing feature
requests for existing products as well as ideas for the
development of new products not yet available.

Listed so far on this page is:

1) EPC1: External Plexus Control, allowing
standard keyboards to interface intelligently
with Tonal Plexus keyboards
2) mini MOD: a modular generalized MIDI controller
with modules for Bosanquet and Wicki layouts
3) MTR1: Megatuner, Vocal and Instrumental Tuner
with pitch and interval recognition
4) Tonal Plexus Prototype Lever Action Keyboard
(Velocity Sensing!) a design principle which may
inspire some interesting discussions

I hope you will find the developments at H-Pi exciting
and good, and I encourage you to join the H-Pi
community discussion forum to talk about the
possibilities.

Cheers,
