Trigger IO...looks good

Well the trigger IO works straight out of the box. Just soldered some 1/4" trs jacks onto the end of my original ION cables and away it went.

I have configured my drumset in a 3x3 array. Its not a real set so it need not look like one...

Almost finished a new kick trigger so will post a pic. Dont know what to do with the Edrum - with a proper midi trigger, it might just work.

If anyone is actually reading this in the UK, it can be yours for £10 posted . message me. No guarentee - you have read the blog :)

Everything is on hold until I get a USB-MIDI module...


Admittedly, my USB-MIDI thingy was only 3 quid and worked fine on my keyboard, but it might not be able to handle the edrum as well. As soon as I can get hold of an m-audio or edirol unit, ill restart the project.

I would love something like a UA 20 so I can plug my guitar in too. (I currently use a guitar-link copy which works but suffers from loads of noise

these go reasonably cheap S/H but maybe not cheap enough...

Still got the Crosstalk


A real pain, is this. Have gone over the soldering and checked for dry joints etc. I have added some grounding and shortened the cables a little. all unused inputs are grounded and all pots are in place


I still get the odd cymbal triggered off the snare. I still get a rim instead of hi hat sometimes. Still get the odd bass drum instead of a cymbal..

When the xrosstalk occurs, there is no activity on any other channel . Crosstalk velocity is high too.

Might roll back the firmware and give that a go

Ist full test. hmm

Ok so I have stuck pots in all the pads and grounded unused inputs.

My Problems are. Snare triggering unmapped  notes. It is crosstalk, but internal as there is no indication on level meters

Getting  missed notes too. Done tests on this and the input side seems to be working, but get the occasional missed output.

I am just learning to bang the pads so I am up against it. Frustrations make it hard to want to continue

100_3225 100_3227

Its all a bit rough. But I like rough so hey-ho.

The unit works well but I have a bit of annoying crosstalk. There is no Input activity so it might be something like noise on the connection between the board and the USB midi. (I didnt screen it as it was so short - maybe a mistake)

Ill contact admir via the forum for advice.


Actually I think it is fine. I havnt fitted the pots in the heads yet and there are some inputs ungrounded. Also, I had set the thresholds on the snare/snare  rim at 2 so there was low level noise. As soon as I turned those up and frigged the unused inputs, it seemed like it will be all good

Happy days

First Midi Test

Had another fart about tonight

1. Added a Clamping input to Multiplexer (copy of megadrum's analogue input) to use a Cymbal #2 . Works fine...in fact I might do the remaining ones like this. Grounded the rest of the unused inputs.

2. Chopped up my USB midi cable and soldered to board. Will eventually solder to the existing USB socket on the ION board

3. Connected up 9 mini jack sockets (without pots; I have only got one! )

Beer is optional

Also connected up the navigation buttons.

Connected up and it works fine, except I am getting some ghost notes here and there. I dont think it is from the Edrum as there is no channel activity (probably noise on the usb-midi )

To get over it, I tried filtering through the excellent ETRIGGER by aquawicket which worked really well to only send the  wanted notes. 

Next. Add some pots (maybe) and get it in an enclosure (maybe)

..or just stick it on the floor and play. Need to make a kick trigger though
