Wow man this is amazing. Thank you kindly for sharing the schematics. I wanna try building some of the circuits. Would I be able to send a square wave from a schmitt trigger oscillater as the trigger? I have an arduino but haven't messed much with it and def never send pulses out. Thanks again you nailed it! So cool.
Thanks for the kind words! A square wave would definitely affect the circuits differently than a pulse, I highly suggest breadboarding your idea first to see if it sounds good or not because you might get audible bleedthrough. You could however run the square wave through a simple RC high pass filter, thus turning it into pulses. Make sure to take care of the negative pulses with a diode for example :)
oh nice thanks for the reply. you got a point. you know more about all thi than i. even the housing on this is very pro . how did you fab the enclosure? do you plan on selling this model ever?
@@jkuebler89 The enclosure is actually from a portable UHF radio. I often visit the 2nd hand store here, they have all sorts of wierd old and often very dusty stuff lying around haha. Unfortunately I have neither the tools nor the space here to build enclosures myself, otherwise I'd definitely be doing that! I do have plans to make commercial products out of some of my projects. I've been working on a portable drum machine the past days (video's posted yesterday ;) ) and I have a string synthesizer module on the way too. It'll take a couple months before I'm even close to being ready to sell stuff though :)
Hello, my tone control does not work, I replaced it three times, no reaction! Used a TLo72 for the snare, should be ok? The diodes are 1N4148? Is the tone controller connected to the two 47N capacitors, it looks like this on the schematic ?! The 1UF at the exit, I don't see where plus or minus is there, I took a bipolar! would be great if you can help, great little drum machine! The resistance in front of the 27N is a 4.7K? or a 47K, you can hardly see it!
Different opamps tend to behave slightly differently with these circuits, but it should work as far as I know. Diodes are small signal ones, not sure which ones I used. Yes those are two 47nF caps, it's one half of a twin-T circuit. 1uF is indeed a bipolar electrolytic capacitor, the plus goes on the side of the 10k resistor. 4.7k yes :)
How did u join the output of each module? And Could you tell me which pins you used for your inputs in your arduino code? i can only identify the CD4022 inputs. Thanks man, i'm trying to build your Drumique.
I think I just passively mixed the outputs, perhaps into an buffer opamp to prevent loading on the ouputs. I'd have to open it to be sure :P As for the pins: - 8 and 10 are the 4022 clock outputs - 9 and 11 are the 4022 reset outputs - A2 and A3 are the two return inputs from the buttons, no idea why I used analogread there btw, since analog pins can be used as digital ones...
Thank you a lot for this project!!!
No problem :D
