![]() If I figure things correctly, I need crapload of ports to make this happen, I need to merge the MIDI outs from PC3K8 and my audio interface to be able to control them all and record/playback everything properly. Boy, was that a stupid idea! I got a bunch of cables that don't even send or receive SysEx!!! To the bin they went. ![]() Also, I plan on adding more rack synths in due time, so ideally I'd need something that has a few ports extra.įirst I tried ordering a bunch of USB-MIDI cables from eBay and using a USB hub. What I want is to be able to control all of them from my PC3K8, AND my computer, and be able to do SysEx dumps and receives on ALL of those racks to my computer (not possible to do dumps for Blofeld, as it only has a MIDI IN, but can be done via USB). The Arduino MIDI Library is very versatile and you can make many different projects with it.I'm looking to bring my racks together to my master MIDI controller (Kurzweil PC3K8) and my computer (currently using TC Electronic Impact Twin, but at some point will upgrade to RME FF802). If all goes correctly, your app should pick up the Arduino as a MIDI instrument and it will start playing C over and over again. Now it is back to "MIDI mode." Now plug the Arduino back into your computer and open your favorite midi app (Something like Garage Band). Next unplug the Arduino and remove the jumper on the ICSP header. ndNoteOn(C3, 120, 1) // Send note C3 on with a velocity of 120 and on channel 1 MIDI.begin(MIDI_CHANNEL_OMNI) // Begin MIDI and listen to all channels MIDI_CREATE_DEFAULT_INSTANCE() // Create an instance of the midi library We will upload a simple code that will play a note on and off. ![]() Plug it back into your computer and it should now show up as an Arduino. When you plug the Arduino (once the firmware has been changed) you should get a message like "We're setting up the device 'Moco/LUFA'." With the Arduino as a MIDI device, we can't upload code to it with the ArduinoĬonnect a wire/jumper between pins 4 and 6 on the ICSP header as shown below:Īdding the jumper will set the Arduino back to "normal mode" (So we can upload code to it). Just skip the part "Download updated firmware".Īlso, be sure to flash dualMoco.hex to the board! ![]() NOTE: Only the Arduino Uno and the Arduino Mega have a 8u2 (or 16u2)įollowing the instructions here, flash dualMoco.hex to the Arduino. This is helpful because you can have a MIDI keyboard that is connected to a computer with a MIDI software and the type of instrument can be customized.įor more info on what were about to do (Please read):īefore we start, make sure that you have Arduino IDE and MIDI Keyboard (Or any other MIDI app) installed and ready to go. The benefit of MIDI is that the commands only send the pitch and the velocity, not the type of sound or the volume. MIDI commands are sent over a DIN cable or, more popularly, USB. The most basic command, Note On, sends the name of the note (pitch), the velocity (how hard the note was played), and the channel. MIDI ( M usical I nstrument D igital I nterface) is a protocol that uses a series of commands to send musical notes. Last year, while on an all-night-long adventure with my church, one of my over-caffeinated friends came over to me and told me that we needed to make a "really awesome musical instrument with lasers!" I'll put up that project when I'm done but for now, here's how I found out (after much googling) about how to use the Arduino as a MIDI device.
