Regarding the judgment of the head and the rim, it may be necessary to improve the code ![]() If you lower it too hard the rim will sound when you hit the head. In searching for peaks, values are taken consecutively for several milliseconds after exceeding the threshold. If you lower it too much, you may get out of sound when you hit repeatedly. If you raise the value too much, you will get a sound twice with a single hit. It would be nice to set the value from 1 to 10. Please refer to the image.Ī value for judging that the beating is over. If you lower it, you will gain high velocity even if you hit softly. The lowest value at which sound comes out If you watch at the latter part of the video you will understand how to operate. ![]() Then, pressing the EDIT button again confirms the change. When the EDIT button is pressed while the instruments and items you want to set are displayed, you can change the value with the INC / DEC button. Select an instrument with the inc / dec button and select the setting item with the next / back button. Nevertheless, setting is necessary depending on the size of the piezo, the size of the pad, the hardness of the sponge foam. In other words, this is made for debugging code, so there are items that do not need to be changed. In making the code, it was troublesome to rewrite the code each time the value changed, so I wanted to be able to change the value with arduino alone. In other words, when writing code using the arduino IDE, you have to short-circuit the pins as shown in the picture. If not (when not short-circuited), arduino UNO will be recognized as a MIDI device. If you short-circuit the pin as shown in the picture, it will be recognized as normal Arduino. Just replace "Arduino-usbserial-uno.hex" with " dualMoco.hex".Īfter rewriting, your Arduino will be recognized as a MIDI device. Next,Please proceed according to this site until the description below. This instruction is how to rewrite the hex file.įirst, Download "dualMoco.hex" in your PC and move to Downloads. ![]() So, you have to rewrite the USB chip (ATmega16U2) used in arduino UNO. If you connect normal arduino UNO directly to iPhone, you will get an error message like "Arduino UNO is not compatible". as a midi device without any additional hardware. In other words, make arduino be recognized by iPhone etc. With usb cable alone, you can send midi signal from arduino.
