MIDI in does not work
When MIDI data arrives in the Shruthi-1, an icon is shown in the corner of the display. The icon is:
- A note for note messages.
- A ~ for controllers.
- A pitch bend lever for pitch bend.
If these icons show up and you don't get sound, make sure that the master keyboard is sending to the same channel the Shruthi-1 is listening to.
If you cannot see those icons, check that the 6N137 optocoupler is correctly inserted.
If MIDI doesn’t work, check that the optocoupler is correctly inserted in its socket. Also, check that you haven’t swapped the EEPROM and the optocoupler.
