In fact they are not true FAQ, but the blog of Dave (http://arduinodrumkit.wordpress.com/) is full of interesting ideas and answers to questions that I often receive by e-mail. It is also written in proper English and not like mine :D ... so I recommend everyone to give it a look. In effetti non sono delle vere FAQ ma il blog di Dave (http://arduinodrumkit.wordpress.com/) è pieno di ...
New version of the mainboard of the microDrum. This new version supports working at 3.3V Arduino boards (like Arduino DUE) and the MIDI Thru. Of course, to achieve this I had to change a bit the card but can be used in "V5 - No Thru" mode with the same components of the v0.6. In the coming days I will publish the schema and the PDF version of the card. &...
I added in Download page the pdf file with the design of the official plexiglass box. If you build it or do laser cutting, I would ask you to send me the photos of the result.Ho aggiunto nell'area Download il file pdf con il design della scatola ufficiale in plexiglass. Se la costruite o la fate tagliare con il laser vi pregherei di mandarmi le foto del risultato.
After several studies, using different materials and different techniques, I came to a conclusion. The box you see in the gallery is the official box of microDrum.
Today I started to do some tests to calculate microDrum latency. I used a Behringer UCA 222 sound card as an oscilloscope , the software "Electroacoustics Toolbox" to analyze the signal and, for convenience, a MIDI Thru Box to split the output of the microDrum (this have certainly introduced a delay). I have connected an input between the piezo and the microDrum and the other input to one of the outputs of ...
Dear microDrummers, my work goes, I'm currently working on several aspects simultaneously. -New version of ConfigTool for OsX. This version will be released initially in a simplified form and only after I will add the extras including support for VST. -In the version of Mac ConfigTool I'm also working on an interesting option that allows you to export on the iPhone/iPad the DKIT/DSND sounds libraries. Then I'll do ...

Sorry for the delay, I was busy with work. Here are the diagrams for connecting an LCD to microDRUM. The code to handle it is still incomplete, but I hope soon to have the time to finish it. I remind you that the LCD screen is optional and microDrum works fine without it, I added it because you asked me. A friend of mine is building a prototype of the ...
New software version for iPhone / iPad. In this new version there are two important changes: the addition of effects and a simple sequencer. Regarding the effects have I included only the reverb, but the sequences although very simple in my opinion is very effective, both to write short loop and to test the SFZ files. At this point I will cut off the buttons for the tests in the menu ...
