Yessss! I love it :)

Let's do this instead!
Hell yeah, Professor Madbean!! 8)
An original design! I'm really lovin it! 2 thumbs up for the Beanster!
:o
Awesome. Must know how it works... Its like the Goatkeeper except much more practical and manageable. Wonder how it would sound hooked up to a wah.
That's mind bending :o
Fantastic quality video in HD too.

Sick!!! Sounds like the guitar from "Any Colour you like".
Reminds me a lot of this:

Cool sounds madbean, but I feel like I'm missing something...
Which project is the demo of? ???

Not one that exists yet. It's part of a 'modular' series of projects I want to do. The control board utilizes the MV-53 chip which sends out a control voltage. It's also tap tempo. Anyway, you can use that voltage output on any number of modulation based effects, and others.

This is probably the best sounding tremelo I've ever heard! Anyone have any idea what this is based on?
I like the sound of a way more versatile version of the original project. Instead of just focusing on wah, it can interact with other modulation based effects as well as a wah like the example you gave. Your on to something good!

I don't know what this is based but this is a video of the breadboard devopement.

I will ask him (skynet) because he is from my country (Portugal) and i know him from another forum. If he tells me i will let you know what is the circuit on which the tremelo is based on.

Any news on this project becoming a reality? This looks great
I'd really like to build up a versatile outboard LFO and add expression inputs to just about every pedal I have that isn't dirt. I was going to go with a TAPLFO based deal but this looks much more interesting. Any chance this controller will become a project?
speaking of modulation...I don't think anyone has posted a demo of the Quadrovibe....anybody up for it?
Has anyone re-drawn Galego's schematic to be clearer? http://img714.imageshack.us/img714/6888/schemtrem.jpg
Why does there appear to be 2 grounds?
I haven't blinked since the first video demo.
Screw the Dig Dug indeed.
I want the Mad Bean with all the lights.
Love it!

Ok, so I've been trying to break down Galego's sequencer/voltage controller and I've made a couple conclusions. I'm a novice so these are based entirely on observation. I would love it if Brian pitched in to make this project a reality!
- Galego's schematic can be found here: http://img714.imageshack.us/img714/6888/schemtrem.jpg
- He uses a VTL5C3/2 vactrol to convert the PIC18 output to a variable resistance in both circuits. This is different than what Brian used! I think the optocoupler Brian uses is different. I have no idea what it is. Brian's PIC might also be different. I can't see it in the videos. The PICBasic scripting is also different.
- I asked before why there are 2 grounds. There are actually 3. 2 appear to be the same (?). The third is due to the PIC circuit running on 5V (something to do with the MC78L05CP
My free time right now is going toward a LaVache, Zombii, and then a LowRider. I really would like to move on to this style of a sequencer by August. I checked and my local hackerspace (Cleveland) has a PIC programmer I could use. Let's make it happen!

This kinda stuff seems to be in a grey space between guitar pedals and analog synths... here's a link to an existing analog sequencer (the Galego and Bean ones being digital.) These typically run on 4000 series logic chips.

Yeah, I find this really interesting. I'm not sure what the official definition is... but the digital component is being used to control a single analog component of the circuit. From what I can tell the analog signal is never converted to digital. Does the tracking get screwy in a circuit like the one you posted? I'm still trying to learn a lot more about this.
