support MIDI PB too

+Harp does not depend on any particular control surface and can be configured to work with a variety of CV input ranges.  You can use it with anything that can create a continuous voltage as the musician "strums" (could be a slider on a MIDI control surface, a ribbon controller, heck, even an LFO)   I've created a [simple control surface for the iPad using TouchOSC](https://github.com/chinenual/Chinenual-VCV/releases/latest).  The control surface sends both MIDI and OSC messages as the faders move; use whichever works best for you.

+Use the VCV Fundamental MIDI-CV module to capture Pitchbend events sent from the control surface.
+
+* **Channel** - the left fader sends on Channel 1; the right fader sends on channel 2
+* **PW** - the control surface sends the full pitchbend range; configure MIDI-CV to "2 semitones" to create a -5V .. 5V range for the control.
+* **GATE** - If you configure MIDI-CV to be monophonic, you can just patch **GATE** directly to the Harp.  The control surface creates NOTE-ON and NOTE-OFF events for MIDI 64, but all you need is the corresponding gate and the pitchbend info to control the harp.

+Use Trowasoft's cvOSCcv to convert its OSC messages to CV:
 
 * **/1/fader1** - Left pitch - sends 0.0 through 10.0 corresponding to where the left control strip is being touched.
 * **/1/fader1z** - Left gate - 1 when the user is touching the left control strip; 0 when not touching
