Hi forum,

just fould this advertisement about a new controller which lets you play midi drums from any surface where you stick the transducer to.
I think this is really interesting.

http://pulsecontroller.com/welcome.html

I would instantly buy this but since it doesn't support windows and they won't ship to europe, i was thinking of a pure software solution to replace this. Simply place a cheap contact mic on the table or whatever and plug it into the audio input of your computer. Then you would need a software which you could calibrate to the microphone and which converts the trigger to a midi note on with the velocity of the amplitude with a decent speed. Now just connect with your favourite drummachine or sampler and there you go...
Is there perhaps a software solution which lets you do this already?
Thanks,
Nils

I love google!

It seems, the program "eTrigger" does exactly what i was looking for. Sadly i couldn't configure any audio input device since no device showed up.
Any ideas?

if you are using windows than you should try PureData or MaxMsp.
PureData is free...MaxMsp is not.

i more prefer PD because i use linux and under linux there is no Max:)
quite same logic. there are tons of objects like audio input ///adc~
and midiout or noteout...
you have to create connections/nodes between the objects...

Great info, thanks.
I actually thought about MaxMSP before but thought there might be something more "simple". I will definitely have a look into the other program.
Cheers,
Nils

PS: Do you think the project is doable latency-wise for real-time triggering?

I have actually found some patches for Pure Data which allow me to do the same as the Pulse Surface Controller. It will just be a matter of tweaking them to my needs. I will have to check if latency is all right. Anyone interested?

Hey the Theremin to midi thing was very cool!
This is a good start for a drum trigger thing:

Couldn' test it though. No microphone Embarassed

buy some cheap piezzo:

or you can try some old headphones...like mobile headset.
its easy to amplify the signal in PD.

Some great information on drum triggers is available on the Paia website.

Even includes a nice schematic to use with the DIY drum pads.
