Step 3: about drum samples

flexi uses audio format samples to play as soon as keyboard key is pressed


the quality of u r drum depends on drum samples u r using

the following is ahuge drum machines ( Yamaha , Ronald ...and more professionals ) collections from in tor. format ..make sure u have u torrent client installed :-

http://torrentz.eu/c339b4b1e7915f6a40364f0fbf472fd2ab798678

beginners may try the default samples already present in flexi software

i have also attaches some sufficient and good samples

the torrent is too heavy ( 600 MB) so choose only which files u need ( u r favorite brand )

<p>https://www.youtube.com/watch?v=m8VNFrXh8vs its in another language but if You watch its easy to understand. It uses LED's lit by the LM324 which is powered by the the keyboard circuits power and actuated by the Piezo. Light Dependant Resistors (LDR) are used in heatshrink tubing with the led's. The Light Dependant Resistor is connected to the keyboard circuit. when the Piezo is hit it lights up the LED which reduces the resistance of the LDR which completes the circuit on the keyboard.</p>
<p>i just can't make it works, i have wired the piezo amp like the schematics but this not works, how i can make to know the amp works? is the amp not usb powered or something? or a ground conection that i miss? i'm making this for a drum controller for phase shift, but with my real drum set :D</p>
<p>VIRTUAL DRUM PAD TO CONNECT AMPLIFIER WITHOUT COMPUTER....</p>
<p>DOES ANY STEP FOR USING THIS VIRTUAL DRUM PAD LIKE AS REAL DRUM PAD WITHOUT COMPUTER TO AMPLIFIER...<br><br>DOES ANY STEP OR INSTRUCTIONS FOR IT...</p>
<p>Cool, good info and DIY.... Thanks</p>
<p>Is this connection correct?</p>
<p>i made it... sorta... used the keyboard chip.. but did not use the piezo's.. instead used small push button switch... tnkz for your idea</p>
<p>Congrats. Do you have some video of your finished product? Also, what sort of push buttons did you used? </p>
Is this drum set velocity sensitive i.e sounds louder when hit harder?
I think not, because keyboard respond just to connect 2 wire
but my question is can we make this circuit without ic..........using transistor
A circuit using a transistor or two per amplifier with its attendant resistors and capacitors<br> is far more complex then one IC that has four individual amplifier / comparator units<br> in a single14 pin IC (Integrated Ciircuit)..
So we can't amplify without IC ?
Is there any alternative way to make it velocity sensitive?
Can i use piezo speaker on place of piezo transducer.......and can I connect Piezo direct to keyboard without any circuit......
Guys can someone add a proper schematics? I doubt it's gonna be hard for someone with tech knowledge. I don't have it. Can do the drums but need proper schematics. Thanks again.
Hey every one....this one is a similar one....Except that u wont ness the resistors at input since our input is small...and the common grounded wire of all a ics should be to the common green pin on the keybaord ic......and the individual output of each ic will go to the individual input of keyboard ic....Please understand the basic idea...then u can easily link...best luck..:-)http://www.electronics.dit.ie/staff/tscarff/Music_technology/8way_drm2/drmpre_ct.gifReply
Hi Siddiq, <br>I'm having trouble mounting the plate, why not have much knowledge circuit, you could send me the board layout please? <br>After I mount the board you pordeira orintar me in connection with the keyboard? <br>I thank you for your help. <br> <br>Thanks for the posts.

Plz wait. For the new one....as i say experiment u r own way.....as i did it accidently...<br>For now... I can say it is a opamp as comparator...without any driving power....the feed back is 220 ohms fixed.....individual sensitivity is 470ohm trimmer i.e. Variable one....and group sensiivity is 4.7k variable...see the schematic and my completed circuit carefully....sorry
Hello Siddiq4321, <br>please help me <br>I am struggling to understand. <br>you could give me more instruction on how to assemble, <br>you have some tutorial video? <br>Please, I beg you <br>thyagolukas@yahoo.com.br

Hello Friend, <br>You got the most simplified circuit? <br>please help me also, <br>I'm having trouble understanding this.

Thank you sir for this great instructable. I was just wondering if you could put bigger pictures of those schematics, I am new to this and can't take a step without copying it :D.<br>Thank you.
if you hover your mouse over the image, an I will appear in the top corner. Click this I, and it will take you to a larger image
Well....try enlarging the image.....or open it into new window...<br>If not....reply with u r email id....i may mail u the pdf...:-)
Can i also use this to connect piezos to my logitech usb gamepad controller .
Hi,<br><br>The other potentiometer , what is the value. I saw it like 5000 K ohm. <br>The one more thing, the component between the -ve and +ve line on the upper right hand side, what is it?<br><br>If instructables reduce the pic quality, can I be a member and get the high quality diagram?<br>
Cannot see the diagram clearly.<br><br>Is it 470ohm or 470K ohm. 220 or 220K ohm. Can you post a clearer diagram. Thanks
For now...its is 220 ohm and 470 ohm which we write as 220E<br>The pixils of the image r lowered by instructable
I like it, but I don&acute;t understand how to make the circuit 741. Can you do it again? Thanks from Argentina!
Yes t is very necessary. U can use trim pot / trimmers / potentiometers in place etc...
but i can use this? http://www.sourcingmap.es/smapimg/es/n/11c/1000-unidades-150v-16w-47k-ohm-axial-lleva-resistencias-pelicula-carbon-150862n.jpg
no ...<br>u can use this <br><br>http://www.digitaldandt.org/db/uploads/data_sheets_rev/Resistor_files/resistor4.jpg<br><br>or<br><br>http://upload.wikimedia.org/wikipedia/commons/thumb/b/b5/Potentiometer.jpg/225px-Potentiometer.jpg
thanks<br>
http://upload.wikimedia.org/wikipedia/commons/thumb/b/b5/Potentiometer.jpg/225px-Potentiometer.jpg <br><br>or<br><br>http://www.digitaldandt.org/db/uploads/data_sheets_rev/Resistor_files/resistor4.jpg
See. It carefully.... Study the ic...opamp as comparator is being applied here..between terminals 2 and 3. ..or ur self thnink about a new idea...
what is 470E presets ( fine )? thanks you.
Its the 470 ohms trimm pot or the trimmer like the potentiometer. Any may work. <br>Fine is for fine sensitivity...<br>
But is it necessary? <br>another question, Does the 4.7k preset has to be potentiometer necessarily? thanks
i tryd did it bt i got some prob about making signal amp..so if u can pls upload a some video or pls mail me your pdf file.<br> thank you and nice job..
See the single piezo cicuit carfully. Or try u r own methods. I m not sure this would work with u. <br>
