  I'd like to know the process to check the tone of each instruments while building, similar to what's done on the x0xb0x assembly, in order to debug a bad section if necessary before moving to the next one.

thank you Vincent

DIGITALWRITE is my friend

code snippet for a 1 ms trig every second on pin8 of arduino UNO:

Code: Select all

int ledPin = 8;               

void setup()
{
  pinMode(ledPin, OUTPUT);      // sets the digital pin as output
}

void loop()
{
  digitalWrite(ledPin, HIGH);   // sets the pin on
  delay(1);                  // waits for a millisecond
  digitalWrite(ledPin, LOW);    // sets the pin off
  delay(1000);                  // waits for a second
}

Best regards

To check instrument before start building the next one you need to send a 1ms 5V pulse signal in the Trig input and connect the Accent input to 5V. (cf schematic to find this points).
The best and easy way to make it is to use a Arduino.

Beest regards,

Vincent, could you give an example with one of the instruments? Where to connect this, say, for the bass drum?

My Arduino is flashing the test LED connected to pin 8, but I'm not sure I understand correctly.

I need to connect the pulse signal from the Arduino to R155. Then? I don't know where the Accent input is that needs to be connected to 5V.

Also: will I hear the signal at R175? At line level?

thanks for helping me out of my confusion...
