Last year I did a project where I sensed the vibration of a string and turned it into light and audio. Very fun and cool! I used Maxuino for this, and now, a year after I will do another project in a similar fashion. But this time I am trying to do it from "scratch". I had some issues with the layout of Maxuino and Sensorbox and felt they were too large and heavy for my purposes, and in general I do not like applications and tools that try to do everything. And I also like a very flat structure where it is easy to understand what is happening behind the curtains, i.e. no encapsulation porn (i know that there are many valid reasons for this though). But before I attempt a shot at a super simple little analog2digital-application, I would like like some feedback on the setup I am working on now.

I do not know much Max, maybe 2-3 weeks all in all is what I have spent, and the workflow is very foreign to me.

I would like to automate as much as possible (i.e. generate) and share information and conversions as speedy as possible. Actually, any tip whatsoever would be great to hear.

I'm afraid posting an image of your patch, with no clear description of "the problem" and your expectations, there isn't much to say here. More questions than answers. Are you using multiple sensors connected to your Arduino? This appears to be the case with your [sprintf] and [send input_list] objects. I notice that you 

 to be using 10-bit input into Max, which you then convert to 7-bit, which is not optimal. If you've only been using Max for 2-3 weeks, this patch looks actually quite sophisticated; is it your own? Are you running Standard Firmata on your board? Please tell us exactly what your setup is, the issues you are facing and what you wish to achieve.

There is no "problem" actually, I have just written a patch for a show that takes in serial input from a simple arduino patch, no firmata. the data comes in like "/a/0 123".

Originally most of my lists were manual, like, I had a route-object for each of the /a/0-15 that was arriving but got help to create a dynamic send, otherwise yeah it is my own.

What the problem might be is that last year I did an installation and were using Maxuino but back then I didnt really understand how it worked (and it drove me crazy) and so this time i tried to do write something more basic that I could "oversee". I need to know how things work in order to feel good about using it.

I would like to release a simple patch after the show so that others that are kindof like newbs like me can simple introduce Arduino in to their workflow. And because I only figure out how to solve the specific problems i face, i have no large grasp of Max coding conventions and optimizations. I would like help with this. If someone shows me a Javascript-function or some CSS/HTML I can quickly see how things can be "better" and so my request is something like that, for the experienced ones to point out what is "bad" Max, and so that I can learn how to write better.

You mention 10-bit to 7-bit, i will search around for that, i do not know what you mean actually so this makes me curious.

Can I see your Arduino sketch as well? Then I can form a better picture of your interaction system.

in your Arduino Translation segment, you have [zmap 0 1023 0 127], which appears to be a redundancy, sending two bytes per reading per sensor, and then rescaling to 128 values. I would suggest just sending one byte then dividing by 2. But I'm a little in the dark, not least because I am no Max guru myself. I'd love to see/hack your code and patch.

I have segmented my max patch a bit, I include the whole project + the Arduino-sketch. The Arduino code I feel is very primitive, but that is also a field where I feel insufficient.
