Re: Trigger/Gate Time!

it's ok with 2222 ,3904 ,547

2222"A" is choose by with my simulator, and it was the most sensitive with 0,59v

3904 trig with 0,64v
bc547 with 0,61v

Re: Trigger/Gate Time!

you can remove the led for more voltage and put it in pin6 with this code : boolean buttonStatePLAY = 0; boolean lastButtonStatePLAY = 1; const byte trig = 0; // trig out // pin 5 const byte led = 1; // led // pin 6 const byte buttonPLAY = 4; //gate in // pin 3 int dly = 4 ; // trigger time in ms vo...

Re: Trigger/Gate Time!

of course it's very easy with an attiny

Re: Look Mum No Computer - BIG BUTTON DIY build - Verified???

that's not in the code,
but may be just add a transistor to boost the power ?

you're a great genius! it's perfect now
thank you so much.
the diagram below is so cool (for me)

Re: pad / piezo interface env/vca/trig (help plz)

thanks for your answer but not sure to understand
may be there s no need 10k to protect op now ?
like this ?

Re: pad / piezo interface env/vca/trig (help plz)

chaotic in the sense that the sequencer forgets steps or goes too fast, a bit like a random number.
not clean

this version is more reactive but not very stable yet

Re: pad / piezo interface env/vca/trig (help plz)

ok, thanks i will protect op with 10k ;
but for the clean pulse the problem is strange because when rené is ok, my doefper is not ok...
i look for something compatible for all
i tried a lot of schem with transistors.. but nothing very clean
thanks again

pad / piezo interface env/vca/trig (help plz) SOLVED

hello I developed this very simple interface in order to use it with pads or piezo. the detection, envelope and vca part works very well, however the trig out part is not perfect, it works but it is not very stable. would someone have a very simple idea to stabilize it a bit ? thanks http://pjmnc.fr...

Re: Look Mum No Computer - BIG BUTTON DIY build - Verified???

yes 12v directly to vin i changed the code a little for that, just add input_pullup (to create virtual resistor directly inside nano) for you plan, you can change the line 159 pinMode(ResetButton,INPUT); to pinMode(ResetButton,INPUT_PULLUP); and the line 372 if(ResetButtonState == HIGH) to if(ResetB...

Re: Look Mum No Computer - BIG BUTTON DIY build - Verified???

the hex file is just the compiled version of the ino file. (same code)

I use avrdude and a usbtiny to flash my arduino cards (because it's faster and you can modify the fuses)
but arduino id is ok too
