Here’s a cool handheld drum machine you can create with Arduino

“I’m the operator with my pocket calculator…” — and now you’re the engineer/builder, too.

This excellent, copiously documented project by Hamood Nizwan / Gabriel Valencia packs a capable drum machine into a handheld, calculator-like format, complete with LCD display and pad triggers. Assembly above and — here’s the result:

It’s simple stuff, but genuinely cool. You can load samples onto an SD card reader, and then trigger them with touch sensors, with visible feedback on the show.

All of that is feasible thanks to the Arduino MEGA undertaking the heavy lifting.


The mission:

The thought is to develop a Drum Machine employing Arduino that would simulate drum sounds in the 9 keys available in the panel. The Drum machine will also have a display where the user can see the sample name that is being played each time, and a set of menu buttons to go by means of the list of samples obtainable.

The Drum Machine will also use an SD Card Reader to make it achievable for the user to shop the audio samples, and have much more playfulness with the equipment.

Korg does bass and drum synthesis with volca kick

Just in under the wire before Roland hosts their personal product shindig subsequent week, Korg are here with a new volca to announce. The latest handheld instrument in that blockbuster line is something of an outlier: referred to as “kick,” it’s much more specialized than the rest. But it does look like a lot more than just a box for producing bass drum sounds (though it’ll do that if that is what you are right after).

Now, in my view, the very best feature of the original volca drum machine, volca beats, was its enormous analog kick. But Korg is betting they can win us more than with anything still better. The volca kick utilizes the self-oscillating resonance of the classic MS-20 filter as its sound supply.

That need to give you plenty of bass drum variety, extending some of the possibilities to other drums (toms) and melodic lines (utilizing it far more as a sound source / synth normally rather than a “kick” maker in distinct). And it can certainly be exciting playing with melodic basslines that offer the function a kick drum normally does.


What might make you want to buy this, even though, is that it’s a volca. So, you have battery energy, loads of hands-on control, and a versatile step sequencer with touch control. That step sequencer now extends to a new effects function which Korg do not completely explain but which sounds cool. Verify out the rolls, although – while a “roll” does not truly make sense for a bass drum which you play with a pedal, the rhythms are set up to conveniently let you access standard polyrhythms and syncopation. (Sorry, if you want 1/32-note bass drum trills, you will have to resort to MIDI.)

This isn’t the first solution of its kind. The Jomox MBase01 and MBase11 had more or much less the very same thought — make a little module that specializes in kicks. And as I’m imagining you may do with the volca kick, you can use the MBase as a melodic synth module, also. The Jomox has nothing at all like the Korg’s step sequencer, even though, or the outstanding volca hands-on controls – MBase users are either dialing up presets or controlling parameters via MIDI. But this may nevertheless be a horse rase: the Jomox sounds amazing, it may well better emulate the 808/909 sound than the volca does, and it has a dedicated trigger input if you are using it with some thing other than MIDI.

Given that Roland are dubbing their event next week “909,” I’m guessing there could be some connection to a drum machine there. Just a hunch. On the other hand, you wouldn’t expect anything remotely like the volca kick from any main manufacturer but Korg.

That stated, I believe the volca kick is an exciting entry and worth a look. And it was possibly a greater thought than the volca clap or volca cowbell, but… the night is young.

Also: that LED appears like it says hich. Oh effectively. ?

US$ 159.99 in October.

Ruismaker is an iOS drum synth that feels like hardware, performs like a plug-in

Computer software drum machines are not kingmakers the way hardware is. So Bram Bos of Eindhoven is not a household name the way, say, particular hardware makers are. But back in the 90s, Bram’s HammerHead Rhythm Station was 1 of the first pieces of application that showed what a drum machine in computer software could be.

Flash forward to 2016. Bram is right here with an iOS app that is all drum synth – no samples. And whilst that puts it in a category with some other apps, it requires a slightly distinct method.


1st, Bram advertises it as “the most hands-on” selection for iOS. The UI is developed like hardware – and that means actually. Bram was already prototyping hardware with a Raspberry Pi as the guts. So what you get in the iOS style is anything that is, on screen, laid out and sized in the same way as hardware would be. That makes it extremely much unlike a plug-in to use, simply because you do not just use the touchscreen as a window to a bunch of software program parameters.

Second, even though, it is really a plug-in. Although there are other wonderful instruments on iOS, like Elastic Drums (also a drum synth), Ruismaker operates as an AU plug-in. So that implies you can drop it into software program DAWs like Steinberg’s Cubasis or Apple’s GarageBand (every now pretty potent alternatives). I really hope Bram uses AU cross-compatibility and makes a desktop version, also, as I really like the thought of projects becoming transportable amongst mobile and desktop. (Like the iPad as I do, sorry, the laptop is exactly where stuff gets completed.)

Third, and in fact the reason to use it, Bram has taken a extremely specific strategy to sound. There’s a separate synth model for every instrument variety, modeling the analog circuitry you would anticipate out of a drum machine. So you get a combination of models that’s specific to Bram’s own vision of how such an instrument ought to sound – and that is good.

All of this comes with each other in a vision that is really playable. Bram says he’s made it quite efficient, so you can run lots of plug-in situations on your iPad, and nonetheless get low-latency audio.

If you are curious about that hardware project and exactly where it went (plus where it is going), that is covered in an elaborate weblog post that I believe will be exciting to developers.

But right now, this is yet another exceptional selection for the iPad. And it’s just US$ 4.99.
