e-drum DIY / modifications / Aquarian / Miditronix InBox Schematic?
« on: April 17, 2019, 05:20:50 PM »
Hi all,

I'm considering using an FSR pad for my snare as part of a DIY build. Wondering if someone has an InBox and would like to share the schematic, i.e just a couple of photos of the PCB. I'm guessing it's a very basic circuit. If I were to guess it, it would just be a series resistor for the FSR (current limiting) and maybe a series cap for the output.

Any thought or knowledge on the topic is welcome!

Does anyone on here have experience with the Roland PDX-12? I am looking for a snare pad which has rims that are not as hard as regular acoustic drum rims, since I play rimshots. I do own the Yamaha XP120SD but it actually doesn't trigger all that well with the 2box.

I played around with the hihat calibration again today, the pedal-related issues I had with the 2box hihat was due to using the normal felt washer under the magnet of the hihat. The magnet-base that comes with the 2box hihat must not rest on a felt washer or the like, because that messes up the pedal signal.

The weird sounds I was getting was due to the pad triggering (wrong zone) instead of the pedal. It took a lot of tweaking to get it to work as intended.

All that said, I will go back to using my acoustic hihat.

I got a 2box hihat. Comparing the Yamaha RHH-135 with the 2box, the Yamaha does foot chick / splashes better and is easier to calibrate. Transitioning between levels of opennes seems better with the 2box. I was expecting a bigger improvement. Without having the 2box to compare with, the Yamaha didn't seem completely compatible.

With the Yamaha, you have separate velocity curves for the pedal and the pad. With the 2box, the pedal velocity curve does not affect the splash level, (Edit: it does affect the pedal) which is too loud, and does not trigger well. This is probably due to the pad triggering instead of foot chick, which also explains the weird foot chick sounds I get with the 2box hihat. Maybe this can be solved by lowering the level of the pedal samples when creating the dsnd in the 2box editor.

I find the edges of Yamaha cymbals a bit too soft. The 2box has a harder surface which I personally prefer, but that is actually the only improvement over the Yamaha at this point. (Edit: no hotspot on the 2box hihat, but the Yamaha does)

Unless I manage to improve calibration, I will probably keep my acoustic hihat.

The old ddrum4 hihat is quite superior when it comes to playability, but the sounds are of course limited. Maybe I'll try it via MIDI.

I updated OS too and suspected it affected the hihat...

I think by now it's safe to say that the RHH-135 is incompatible with the drumit3. I took it apart and checked that it wasn't broken, because it responded so bad. Nothing was broken. The Yamaha DTX500 module performs significantly better in combination with the RHH-135.

Edit: It was the firmware version 1.32.4 that caused the problems.

I made a few measurements on this, you can find them here on the forum.

Nice work!

-  but could you possibly also test with a large-ish kick pad?

I suspect that the latency will be more, since the waveform is larger & thus takes more time to crest.


I set up my old dd4 kick pad with a mesh head and a ddrum trigger (the pads internal piezo is busted). Resulted in a quite sloppy signal, as expected. Latency with the drumit3 was somewhere between 3,8 to 5,8ms. Not a solution that I would use.

Something you might want to consider is the footblaster. Triggers from the pedal instead from the actual pad.
Don't know if it makes any click noise as it hits the pedal, but should give a cleaner trig signal than the Hart Mesh pad you mentioned. Might work with the ddrum3.

I did some testing.

ddrum3 precision pad -> Aphex Impulse (MIDI out) -> ESI ESP1010 at 96kHz samplerate and 48 samples buffer -> Reaper ReaSamplomatic (sample player VST), I got 4,65ms latency.

So that's a tiny bit more than drumit3 "worst case" triggering setting, which gives 4,5ms.

Superior Drummer VST or similar maybe adds some buffering, I don't know. Surely uses more CPU cycles I would guess.

I have the Alesis 16” 3 zone (2 plug ins) and it works fine with the drumit3. The only issue I had was the different sound levels between the zones. I used the Lustark software to balance them the way I wanted and now work great.

Good info, thanks!

It looks like people have got descent results with the strike 3 zone and Roland modules...and drum-tec says it is Roland 3 way compatible...(it is then a piezo, switch, switch implementation)

So it looks like on paper that it will work fine on DI3. :-)

Best regards

Awesome! Thanks for your help!

Hi Cableaddict!
We "met" at the ddrum forum. Please see my post on latency measurements on the drumit3:,3932.0.html

God morgon, Anders ☺

We made the same conclusion - it's not on the compatibility list (which needs updating), and like you, I don't know how the Alesis Strike cymbals are constructed. Hoping someone on here know or have tried them with the drumit3.

Hi all

Is the Alesis Strike cymbals compatible with the drumit3? I intend to use it a 3-zone ride.
