Not for the moment, I need to buy one or bring the yocto to my work placeElSchtroumpf wrote:Quick question : do you have (access to) an oscilloscope?
[SOLVED]No sound, No BD,CH
Yes try to check the individual instruments with an oscilloscope, it's very strange you have no sound even though your sequencer works.
Ok I tried the bassdrum 5V to R152 pulse to R155 and out on R175. I used the tip of my headphone (ground to ground) and i heard the bass drum.
I put back the atmega and tried to "hear" the TRIG signal and there is none

I watched some yocto demo videos to compare behavior. My step-1 LED lights well with the sequencer but when I activate the step 1 it remains turned off and when I activate another step , step 1 blinks. I double checked every solder joints with a magnifier and all power suplies everything is fine.
Any ideas
(still no sound)

check this I did a little video to demonstrate what I said earlier

I'll get an oscilloscope around the 20th of the month I'll be able to do deeper tests
For the step 1 button issue - have you checked with a multimeter if there is a short between any of the pins associated with those buttons?
Dear Electrosymphony,
If you got a problem with all trig signal maybe it come from the 4011.
When did you buy your Kit ? if it was before December the 1th, you have to replace the 4011 in the Accent section.
And for the first step button problem, check R21

Ok I found something I checked R21 it was perfectly soldered then I did a measurement with multimeter I found 2K first I measured other 10k around and they were all at 10k. I removed IC7 to see if there was any interactions between the chip itself and the resistor and I found 10k. Then I tried to exchange IC7 with IC2 since they are the same chip. Now step 1 is working and guess what step 9 isnt
Now I have to buy a new 74hc165 this one was defective.

After the 1st decemberWhen did you buy your Kit ?
I replaced my defective 74hc165 now sequencer works fine. I bought another 4011 too but still no change i have no sound output I think there is no trig signal comming from CPU Is it possible ?
