usbMIDI not declared error

Hey there!

Today I tried the visual micro IDE with my sketch, but it doesn't compile.
It does however, compile while using the arduino IDE.

The board is a teensy 3.1, using teensyduino 1.20 and the audio library

this code(which isn't my actual project) shows the problem:
Code: 
/*
 * miditest.ino
 *
 * Created: 10/31/2014 10:29:01 PM
 * Author: Roel
 */ 

void setup()
{
	usbMIDI.read();
	  /* add setup code here, setup code runs once when the processor starts */

}

void loop()
{

	  /* add main program code here, this code starts again each time it ends */

}


the compiler gives this error:
Code: 
Compiling 'miditest' for 'Teensy 3.1'
miditest.ino:In function 'void setup()'
miditest.ino:10:2: error: 'usbMIDI' was not declared in this scope
Error compiling

I use example defines for teensy 3.1 on this page.
http://www.visualmicro.com/page/Teensy-for-Microsoft-Visual-Studio.aspx
This gives the following defines, I added the DUSB_MIDI later

#define F_CPU 96000000
#define USB_SERIAL_HID
#define LAYOUT_US_ENGLISH
#define DUSB_MIDI

Too bad, it still doesn't compile. :(

has anyone experienced these kind of problems while using another IDE and usbMIDI?
I don't know if more information is required, but I'll provide what is needed.:)

thanks in advance,

Roel
 
I had a similiar problem last night.

I tried commenting out all serial.print commands and removing the usb serial identifier from the project settings but it still told me there was a problem with usb serial.

I don't think it likes using the usb for both functions in Atmel Studio for some reason.

Did you ever get it working?
 
I forgot to do this:

** NOTE **
If you change the defines then click "Build>Clean Solution" to force a complete re-compile the next time the project is built.

Will try tonight
 
This certainly does not look right:

You're defining "USB_SERIAL_HID", which is wrong if you want MIDI. You must NOT define this, because it instructs the USB stack to build Serial+Keyboard+Mouse+Joystick.

You're also adding a "D" in front of the "USB_MIDI" symbol. On the command line, "-D" means define whatever comes after the "D". When you use "#define", do NOT add the letter "D" in front!

Try something like this:

#define F_CPU 96000000
#define LAYOUT_US_ENGLISH
#define USB_MIDI

Thats what I did but it kicked up errors related to usb_Serial. I'll try again tonight, make sure I rebuild properly. Probably just needed to be rebuilt.

Am I right in assuming that serial.print() will still work even if i dont define usb_Serial?

And if not do I need to comment out all my serial.print() code?

I assumed the worst and tried commenting everything out yesterday but it didnt help.

This work with the Arduino Serial Monitor, due to a patch in the Arduino IDE to use the "teensy_gateway" program for communication, instead of real serial.

Other terminal emulators obviously won't support that.
 
Unfortunately I didn´t get the USB Serial + MIDI working.
I use a workaround, with #IFDEF USB_MIDI around midi functions.
When I want to use both serial and midi, I compile it with arduino, and it works.

Thanks for the tips, Paul!
I'll have to try them when I continue working on my synth
 
OK, no joy. I appreciate that this is not your problem Paul.

in Atmel Studio, I set my defines field to:
Code: 
F_CPU=144000000;USB_MIDI;LAYOUT_US_ENGLISH

or

Code: 
F_CPU=144000000;USB_SERIAL;USB_MIDI;LAYOUT_US_ENGLISH

I then select Build > Clean Solution

Then in both cases I compile and get this:
