How it works.

CVtoOSC uses Wi-Fi network via esp8266 to send OSC message, and you will need to change some esp8266 Wi-Fi configuration.

This part, you can set your network’s SSID and Password

#define SSID        "SSID"
#define PASSWORD    "PASSWORD"

If you want to assign IP address by DHCP, comment out this line.

#define STATIC_IP // if you use DHCP comment out this line

If you use Static IP, you need to set your configuration to this part.

#define LOCAL_ADDRESS    "192.168.1.8"
#define LOCAL_PORT       "9000"

This part, you need to set target host address and port.

#define REMOTE_ADDRESS   "192.168.1.2"
#define REMOTE_PORT      "8000"

Message Pattern

MIDI Quiantize

CVtoOSC can convert CV to MIDI message and CV value is adjusted (quantized) MIDI note range (0 ~ 127) and you can choose several musical scales by using pot.
