DIY Touchscreen Drummachine :)



So I finished my touchscreen interface. Myself and a few other lads are putting on a bit of a show for this years DEAF festival (Dublin Electronic Arts). We are going to do a live improvised modular synth session with custom controllers, touchscreens, some handmade electronics noise boxes, 4 camera's and a projector. The touchscreen above was made for that. If you want to come down we'll be in the Twisted Pepper on Friday 24th at 8.00 - It'll be us for an hour and then a mix of Dubstep DJs and livesets for the night.

The vids above are recorded into a cheap webcam. I used the mic in the webcam as well. Next time I'll do a better job. The first vid is a demo of the drummachine just to show that it works and that the touchscreen is very responsive. I have another vid but I had troubles uploading. Try again tommorow.

If you want to build one yourself you'll need MAX/MSP. You can download the demo for a month and give it a go. If you're a student you can get it for $59 for 9 months and the $211 after that. If you are just a working stiff (it's normally $700) go over to Dance-Tech.net and find out if you can avail of the special offer for artists (same deal as students!!!)

The touchscreen was $65 from http://www.lavatechnology.com. It's a 5 wire resitive touchscreen overlay. If you buy one from Lava mention this post and I get a free~ish one :) You can find out a lot about touchscreens if you go to Elotouch. They have a great comparison chart that makes it all pretty easy. 5 wire resitive seemed to suit me the best. It is supposed to be good for a million touchs, works ok in heat and cool (venues) and is pretty cheap.

The last piece was Eric Lyons Potpourri externals for Max/MSP. Although there are some problems for me the simplicity of the sample accurate timing wins out over many other concerns. Download it free from http://www.sarc.qub.ac.uk/~elyon/LyonSoftware/MaxMSP/

The VST effects I use come from Audio Damage. The Reverence and Dubstation are two of my favourite effects. I just find them easy to use and pretty musical. I could have used a reverb external in Max/MSP or built my own feedback delay but I like the Audio Damage stuff so leave well enough alone for now.

Ah hellfire, you're clashing with M83 the same night!

I really want to see that touchscreen in action... how would it work with using Ableton Live or other non-MAX/MSP based applications? And also, is it multi-touch?

Ooooh! Shiny :) cool stuff, I'll now have to add a touchscreen overlay to my WANT list!

AudioLemon said...

Sound lads... no it's not multitouch Imd64. It was €65 from ebay so it's a single touch. It would be great to have something like the Lemur but this is a DIY thing and about €2000 cheaper :)

At the minute it's set up to be used live stand alone. It sends out MIDIclock so I can sync all the other modulars. It'd be pretty easy to send it out to ableton or anything else but I'm trying to get out of that for a while and see what else I can come up with.

AudioLemon said...

Alright 2Bit. It turned out pretty well. I have a vid showing the built but I'm a bit under the weather today so I'll try to post it tommorrow maybe the next day.

oootini said...

cool. deaf gig sounds interesting. out of interest, what other kind of diy noise boxes will you be bringing along? i'm into making similar things.. care to point me in the direction of some cool projects?

AudioLemon said...

Hi oootini, It's another lad in the group is into the electronics. So far I think he's building simple oscillators, noises circuits, decay envelopes and triggers. Nothing too fancy.
He'd know more about it than me but a good place to start is Ray Wilsons http://www.musicfromouterspace.com. Also Ciat Lombarde http://www.ciat-lonbarde.net/ has a lot of wierd electronic noise makers.
If you into making similar things sent me a pic and demo and I'll post it up.

hey Audiolemon,
I' trying to build something like this touchscreen interface but by using a wii-remote to track a users movements. I'd really like to see the other video of this project but I can't find it anywhere. Have you posted it? If so, where can i view it?
cheers,
John

What kind of connection comes from the touch screen into the computer? USB? Or do you have to convert it somehow? Very nice work.

AudioLemon said...

Anon... it's a touchscreen overlay. It's a USB connection. Follow the links in the post. It's about $60 for the touchscreen part.
