MIDI over USB and 5pin using Altsoftserial Library

Hi, I'm using and Arduino UNO as a MIDI device with MOCO LUFA firmware. Can I add a 5 pin MIDI out using AltSoftSerial Library using pin 9 as TX ?

I would like both MIDI OUT to work at the same time, I want to send MIDI to the computer and also to some old synths.

Thanks a lot !

The only way to find out is to try it.

Note that this is not a great solution, an Uno is not fit for the job. Take a look at the Arduino Leonardo, for example, it supports MIDI over USB natively (no special firmware required) and has a hardware UART you can use for hardware MIDI out.

If you cannot find a Leonardo, there are other boards with the same ATMEGA32U4 processor. For example, the Arduino Micro, the SparkFun Pro Micro, and the Adafruit Itsy Bitsy 32u4.

Thanks a lot guys, I got myself an Arduino Pro Micro with the AtMega32u4, it was really easy to make it a MIDI controller using MIDIUSB Library, now the only thing I need is to send MIDI OUT thru the Tx pin at the same time.

Any idea how to do that ? I have connected a 5 pin with 220ohm resistor, etc. I need some help with the code.

Thanks a lot !

The MIDI library (for UART/serial MIDI) comes with a lot of examples.
