I dicovered this project via cdm. It sounds pretty awesome, but I would really love to see some videos of this thing in action. Reading the comments on cdm, I would say that I'm not alone. I was thinking something like a demo of all the possible functions, with and without midi. And then perhaps just some jam videos. I'm gonna order one anyway, but it would still be nice. I'm sure their are others who would want one once they saw it in action.
Hey! Yeah, videos are a great idea. I've still got one more manual to write (theory of operation) and a pile of shipping to dig out from, and I have to clean up the source and schematics and get those up. But then, video city. If anybody else wants to make a video of their WTPA I'll plop it on the site.
andidilu, thanks :) That does indeed work. Neat little vid too! In my opinion, these videos and any new ones should simply be upped to YouTube?! Its convenient and would hopefully add to WTPA's exposure also.
Young!? I wish... ha Im not a YouTube whore by any means. But you must admit, it serves a useful purpose. Particularly now that the vids can be embedded into any ol website. Such as this one. Hurrah! n stuff..
Anxiously awaiting my kit so that I may nail it together and play :D
Here's my video link: I started with a PT-8 plan but couldn't figure out how to drill circles that would work for the switches live. Then I remembered 3 microphone cases (flea market $1 each) and now my live rig has three tiny practical roadcases.
Wow, Sealion -- Thanks so much for that kind video! It's great to see other people use and interpret and talk about these designs -- it feels really good to see people taking them and doing their own things. Also, those Sennheiser cases are tight. Best, TB
hey guys! thought id throw this up here and see what you all thought...! this is me... last night atta show....
its tough to see due to the over dramatic light show.... but there is definitely some WTPA love in there! if anyone is in the san francisco area.... im playing saturday the 12th as well....

Thanks for the comments! Rodrigo - I don't know what you mean about extra momentary switches, there are only six pink arcade momentary buttons installed, similar to the original wtpa layout.
the toggle switches... The one on the outside is the power on/off, the other ones are the bends. From outside to inside: 1.power on/off 2.highpass (sometimes it does not work... strange...) 3.halftime with choppy echo 4.ringmod/resonance 1 5.ringmod/resonance 2 6. FUUUUUUUUUUUUUZZZ!
I have most of the bends documented on my digital camera and will post them up here if you guys are interested. Sorry about the stupid "dancing" and the waaay too much use of the singleshot button together with the pitch wheels - BUT IT IS SO MUCH FUN :)
Now I will have to check out all the other functions soon...
Yeah, they light up, so rather than going separate lights, everything is self contained. They press pretty far down, but just pushing them lightly engages the switch too. It was a toss up between something like this (with LEDs) or the arcade style. I went for this since it would save LED room, and I think communicate what's going on very quickly/efficiently as each button says what it's doing.
The pitch/effect knobs are going to go on the top (above the buttons). I'm not going to use the fine control as it might be overkill. The extra knobs on the front are a 4-1 mixer, so it's volume control 1-4, then master DAC level, and then master level. The input gain is gonna be internal only (set and forget) and the through level will be set/forget as well (100%).
Awesome! Normally I don't use the word "cute", but I would be making a terrible mistake if I said otherwise here. Now, don't go ruining him with that iPhone book in the background :-)
Its a slitghtly modded danelectro fab echo. cheap and - supposedly - bendable. All I did so far was doing the 100% wet mod (allows for 100% wetness, duh) and a delay time pot. all the mods can be found here: http://www.diystompboxes.com/smfforum/index.php?topic=64519.0
I plan on using a smaller arcade button as an on/off, and add some bends too. No bends so far :)
Rodrigo I watched a couple of other videos from you as well. love the DTVGE stuff especially. all your other stuff is really unique as well!
did you build the rollz-5 and the old mr.grassi yourself, or did you have peter build them for you? I am thinking of attempting to build one of those soon...
Thanks! I built it. I built my grassi, rollz, fourses, fyrall(wife did that one) etc.. I would've built the cocolase/sidrassi too but they don't come as kits or paper circuits.
I recommend the lil sidrassi or old mr.grassi to start with. They are relatively simple and sound friggin awesome. The old mr.grassi is more complicated and may require some troubleshooting, but the lil sidrassi is pretty simple.
Peter Blasser rules, and his circuits are great. I went to school with him and he lived down the block for awhile in Chicago. The awesome thing about him is how he knows his Ebers-Moll models so well somehow even with the amount of psilocybin peanut butter he eats. He makes fun of me for using MCUs but other than that I love it when I see him.
I just downloaded the paper circuit for lil sidrassi, just poking around for soundfiles (in addition to the ones on his site) where I can hear one clearly for reference - the trouble with building really abstract noise machines is there's often not a way to tell if you've built it 'correctly' without much comparison. (See also: 4ms Noise Swash - maybe there isn't really a wrong way to do it as long as you get fun noisey output?!?)
Yeah Ciat-Lonbarde, 4ms, and now WTPA are my fav electronics companies by far.
It is a little tough to troubleshoot the paper circuits for the reason you mentioned, but since they have built in amps, you can easily hear if its 'on' (light speaker hiss) or you're getting nothing at all.
For all the 'hairy caps' I would recommend going with mid to high values so you can hear the results better, then maybe going back in and putting in bigger caps if you want (for LFO type modulations of the audio rate ones).
My old mr.grassi is by far my fav paper circuit, and it's one of my most commonly used ciat instruments at the moment as it's so self contained. It's loud enough to use in most settings, it can do noise and melody (sort of), and it's stereo! Here's a vid of me jamming on my grassi like 4 years ago.
It would be amazing to see digital control over peters analog sound worlds. Once I get my arduino chops up a bit I'll probably try to create some brains to massage the braun (of his instruments).
