Problem: If I plug a regular MIDI keyboard into my Tsumani Super WAV Trigger set up in mono mode, with mono WAV files on the SD card, it plays the files just fine when I play the keyboard.
However, if I use a Teensy (similar to Arduino) board with an output to a MIDI socket, it does not work.
I have a Teensy board using the MIDI.h library to send MIDI.sendNoteOn(note, 127, 1); // notes between 48 and 87, maximum volume, MIDI Channel 1 and similar MIDI.sendNoteOff commands out via a suitably wired 5 Pin MIDI socket.

If I plug an AKAI wireless MIDI Bluetooth transmitter into this socket it works fine when paired with an iPad for example running a synth program.
-
If I connect this using a 5Pin MIDI to USB adapter to my laptop and use midiOx program to examine the MIDI commands coming in, I just see MIDI On and MIDI Off commands exactly as expected along with the note MIDI values, on MIDI channel 1.
-
Therefore, I assume my wiring and Teensy software is correct as it is working fine with everything except the Tsunami.
However,
If I connect this to the MIDI input of my Tsunami Super WAV Trigger, (5 Pin MIDI plug pins 4 and 5 wired to 4 ands 5 MIDI inputs on the Tsunami board) I hear no sound from the headphones. I have 4 and 5 wired correctly as
- If I plug a MIDI keyboard, using this same MIDI lead, into the Tsunami, the Tsunami works absolutely fine.
Am I missing something obvious here? I know I can use an Arduino to control the Tsunami via serial but I would like to do it via MIDI ideally.
