+Welcome to the OpenTheremin_V3_with_MIDI wiki!
-
-*** Installation:**
-
-Download and install the arduino code from the following git repository and carefully read the instruction blow. I recommend to first setup and test the theremin as described in the instruction that came with the theremin (using built in sound generator) and then move to MIDI.

-
-*** MIDI synthesizer on the computer**
-
-OpenTheremin MIDI is sending at 115200 baud through USB serial.
-
-Use a serial to MIDI router on your computer such as "hairless-midiserial" (http://projectgus.github.com/hairless-midiserial/)
-And to generate sound from the MIDI signal use a software MIDI synthesizer such as Minimogue VA or QSynth.
-
-
-
-*** Real DIN MIDI interface**
-
-You can also use the OpenTheremin MIDI implemented to communicate with a real MIDI device.
-
-To do so add a DIN connection. See here (https://www.arduino.cc/en/Tutorial/Midi) for the hardware required.
-Set the baud rate to 31250 by changing Serial.begin(115200); to Serial.begin(31250); in the code (-> application.cpp -> midi_setup() )
-
-*** USB-MIDI (HID) device**
-
-Through the code provided in the HIDUINO project the Open.Theremin MIDI implemented can be turned into a class-compliant USB-MIDI device. HIDUINO takes advantage of the ATmega (8u2/16u2) chip on the Arduino UNO. So you get a true USB-MIDI device for plug-and-play compatibility on Windows, OSX, and Linux - just like a commercial MIDI controller. Code and documentation can be found here (https://github.com/ddiakopoulos/hiduino).

-*** Implementation:**
-
-PITCH :
-It uses first note detected at volume rise to generate a NOTEON.
-Then it uses PITCHBEND to reach pitch as long as pitch bend range will do.
-Beyond it generates a new NOTEON  followed by a NOTEOFF for the previous note (legato).
-Pitch bend range can be configured (1, 7, 12 or 24 semitones - One exception is that I desactivated pitch bend in 1 semitone mode because portamento does a better job then).
-
-VOLUME:
-It generates VOLUME continuous controler, starting NOTEON and ending NOTE OFF (when playing stacato).
-The trigger volume can be configured so as we have some volume at note attack on percussive sounds.
-
-CONFIGURATION:
-There is two calibration mode. Best use a speaker connected to the theremin to verify calibration and timbre variation.
-
-Normal calibration of antennas: turn REGISTER POT counter clockwise (all left) and press button for 3 seconds -> Runs normal calibration of antennas (yellow LED blinks until finished)
-
-MIDI configuration: turn REGISTER POT clockwise (all to the right), set the configuration with the pots (as shown below) and press button for 3 seconds -> Records the settings (short blink of yellow LED).
-  VOLUME POT : sets volume trigger level
-  PITCH POT : sets pitch bend range (1, 7, 12 or 24 semitones)
-  TIMBRE POT : sets Channel. In the absence of graduation, timbre variation may help (Wave Form 1 low = CH1, WF 1 High = CH2, WF 2 Low = CH3, etc...)
-
-MUTE BUTTON:
-Sends ALL NOTE OFF on selected channel and stay in mute until it's pushed again. 
-
-*** Results:**
-As long as you are inside pitch bend range you can play with the same linearity as with device's sound (same pitch is audible on stable notes without vibrato).
-On 24 semitones wide pitch bend range capable monophonic SW synth (tested with Gforce's Minimonsta), the effect is rather good: We play on 4 octaves just like a normal theremin. 
-12 semitones capable synth are also good but sometime note transition can be heard.
