    Thanks so much for the feedback Pete. My apologies as I've had some other projects going on - but I am definitely still working on this one. Will share the updated code as soon as I can =D

    Hi Pete,

    Many thanks for taking a look at the code here. To clarify: were you able to get the note repeats to work on your end?

    Also I realized in the above code, in the setup MIDI.begin();...
  3. MIDI note repeat code not working and could use some guidance

    Hi Everyone,

    I am trying to write a MIDI note repeat sketch and I am a bit stuck and trying to figure out why it isn't working and how to move forward. Here is a short demo of the idea using Logic...

    @Pieter I have a MIDI controller project that I am working on that uses the Teensy MIDI library (forty seven effects).

    Do I understand correctly that your control surface library has a wrapper...

    Couldn't have done it without your great help and patience. Thank you! I just tested on the breadboard and it is working great =)

    Now, moving on to a push button encoder for the next challenge...

    hey @matrixrat - I have a follow up on this buffer circuit if you dont mind?

    the sketch of the buffer circuit you shared here, I overlayed pin 4 of the MIDI OUT going to the Tx line on it and you...

    Wonderful thank you.

    One more point of clarification: in your diagram it shows the rear view of the MIDI OUT DIN so the pin out should be as follows?

    No worries @matrixrat , I appreciate the help and explanation! i believe I have a BC557 on hand...

    To clarify: those are 1 kΩ resistors in series there at the base of the transistor?

    thank you...

    Thanks for the advice on the tranistor. this is new territory for me here. can you elaborate a little more on using a NPN, i.e which NPN and its placement in the schematic? thank you...

    Ahhhh, yep - thanks for the eye on that pic on the MIDI lib page in regards to the zener placement - I was trying to figure that out just from the photo too...

    Thanks for the reply @MatrixRat - ahh yep - that differentiation of 5.6v vs 3.6V is not made on the MIDI lib page depending on the board. Thank you for pointing that out.

    As for the placement of...
  15. placement of zener diode for voltage protection for harware MIDI circuit?

    Hi Everyone,

    I want to move my MIDI circuit off the breadboard and following the schematic below found on the PJRC MIDI Library page.

    I am trying to determine where to place the protection...

    No worries - I really appreciate the help! I barely understand what I am doing here as I go along and I have the physical hardware in front of me so you are totally fine! I'm not sure why the modulo...

    Ok here's what I came up with using @el_supremo code that looks to be working (resets the accent pattern with a start message):

    Thank you Pete, that resolved the issue I was having! Very much appreciated. I erroneously thought I would need to have a MIDI start message to handle the setAccentPattern value. Unless you or anyone...

    No worries @oddson, I appreciate you supporting my mis-steps in trying to understand what is going on here. When I print message, it does appear to be firing but I dont think I need to have the...

    Are you referring to the note transposition? If so I've got that sorted in #7 Thanks!

    Moved on to another issue related to creating an accent pattern, also in #7 above.

    Hmmmn... ok, I was thinking I wasn't using the proper call back and handler but unless I am mistaken, the correct start handler is there in set up?

    Ok @oddson, I have a working example now where the transpose offset now works as expected. thank you!

    In the process, I was experimenting and trying to add an accent pattern to the noteOn...

    @kd5rxt-mark thanks for the tip - I hadn't thought about that method. I've got plenty to chew on and will report back when I have had a chance to muck around here. Thanks!

    Ah yes! I forgot that thru is enabled by default - thank you!



    It appears that this may actually be in the works for the lib at some point?...
  26. Transpose / Offset incoming MIDI notes down an octave?

    Hi, I am using the following example to experiment with transposing incoming MIDI notes with a Teensy LC, using a hardware MIDI circuit:

    Excellent - thank you! I just tested it and it worked with no issue.
  28. MIDI benchmark sketch compatible with Teensy LC?

    Is it possible to use this MIDI benchmark sketch below with a Teensy LC?

    It does not currently include definitions for ARM boards but I do see this issue here where it looks like there needs to be...

    Wonderful - I've got that sorted now - thank you!



    Again thank you for pointing me here - will take a look and report back when I have made some progress.

    I am not entirely sure but I re-did the breadboard several times. All the components (resistors, diode, opto) were all ok but I think it was something to have to do with ground. I forgot that the DIN...

    Thanks so much for looking over the breadboard. I took everything down and double checked the connections (reverse polarity, resistor values, wire continuity) so I think I am all set there now. The...
