No, there’s nothing done with a Program Change message other than simply setting a bank variable.
Not sure I understand the question. Changing banks with a Program Change message simply changes the MIDI Note to Track Number mapping for future note events. One thing to keep in mind is that if you hold a key while changing banks, then that track won’t get the Note Off message when you release the key.
Correct. Tsunami follows MIDI Channel Number conventions more closely than the WAV Trigger, in that it supports both dedicated channel assignment as well as Omni mode.

This is one of two issues we found and fixed after the v1.00 firmware went to production. Both issues only affect the mono firmware version and since we ship with the stereo firmware, I was holding off releasing an update in case we found other things. I will post a v1.01 update on the robertsonics download page tonight.
Regarding the “Tsunami crashes very often” comment, I’d like to better understand what you mean. In all the testing and development done for this board, it doesn’t ever “crash” to my knowledge, and I’ve had it running for days at a time.
UPDATE: Firmware v1.01 mono and stereo is now up on the Tsunami download page (link above). This should get you starting all 8 tracks. If you are using the stereo version, you don’t need this update as both issues affected mono version only.

Yes, you can manage the left/right as individual mono outputs by making stereo wav files with silence on one channel. Channel separation out of the PCM5100 stereo line-level output is as good as any high-quality DAC. The on-board audio amp is mono and only connected to the left channel; It’s designed for simple, single speaker, low-volume applications. Hope this helps

I don’t know if you’re still monitoring this thread, but I have a unit here which is doing the same thing. Unfortunately the unit to which I’m able to attach my debugger doesn’t, so I’m not sure quite how to troubleshoot this. Just wanted you to know that at least I’ve seen the same behavior and I’ll update this post when I have more info.
UPDATE: Found the problem - It can happen when you deselect BOTH re-trigger and polyphonic. If polyphonic is left checked (default), it works fine.
I’ve fixed this and rolled it into the next firmware update, v1.30, which will be posted as soon as all the new features are tested.

Trigger inputs can be configured using the init file and the Init File Maker application. One of the options is “Level Sensitive”, which will produce the behavior you want - track starts when the trigger is activated and plays only as long as the trigger remains active. The trigger sense can be changed from low to high using the “Invert” option. I suggest you download the Init File Maker app and have a look.
You want the WAV Trigger. The MP3 Trigger lacks the programmable trigger features.

I am unable to duplicate your issue - it seems to work correctly for me. With re-trigger disabled, I’ve not been able to get it to restart while the track is playing. What’s “a while”? Are you using the most recent firmware version?
This is the first I’ve heard of this - thanks for reporting it. I’ll have a look to see if I can recreate and get to the bottom of it.

The WAV Trigger’s cpu operates at 3.3V but all of the inputs, including the UART RX, are 5V tolerant. Hope this helps.
