Audio For Teensy3 - What Features Would You Want?

[neslekkim]

There is already a USB connector, and a very capable USB MIDI implementation - just select it from the menu. (this does require a USB host, such as a computer, unlike the point-to-point DIN MIDI. On the other hand, throughput is much higher so you don't get congestion botlenecks).

Yes, but why always involve an computer?

If you really want serial MIDI, you certainly can use the MIDI 3.2 library and a small amount of hardware to get it.

That looks fine, have all parts, except for the pc900, but I have the 6n138 so that should be just as well..

Yes, that optoisolator should be fine. What passes for a MIDI electrical spec says "Opto-isolator shown is Sharp PC-900. HP 6N138 or other can be used with changes. "
In practice I have not seen anyone make any changes.

Here's what the audio shield will probably look like....

Hello
Thank you for a great forum and great help
I managed to get the Greber files for the Audio shield for Teensy
Is there a way that you can direct me to the schematic?

Please advise

[mattomatto]

Check the sgtl5000 data sheet for the schematic. I'm using that at the moment. Haven't received my first board to test yet though.

Hello mattomatto
Thank you for your quick replay
I am looking at the data sheet
