Accordion 3d Model UPDATED Download
Bartolome Moosavi
I love the sound of instruments such as accordions, harmonicas, harmoniums, etc. I also like to play around with physical modelling synthesis. How can I go about modelling a sound like this? What are the fundamental components here? Is this possible to do in VCV Rack (or Cardinal)?
I'm wondering if this can be done in my scenario. I have two vue / element ui accordions on a page and I have setup an "open all, close all" button for the accordions. How would I go about giving each accordion a unique ID and pass that ID to the function that toggles the accordions? Or is there a way to share the same v-model with some sort of other unique identifier so I can reuse the function on each accordion but only "open all, close all" of that given accordion section.
Arguably the simplest way would be to wrap a single accordion as a component. This will allow it to manage its own state internally and you can have as many as you want without them interfering with each other.
Last Friday, I led a session on content marketing for another VC firm. One of the concepts I talked about was the accordion model. A couple years ago, I wrote a bit about how I use a sketch model to ideate on my personal content. The accordion model is basically the sketch model through a business lens.
Note, when using v-model to control , the aria-* attributes and class collapsed are not automatically placed on the trigger button (as is the case when using the v-b-toggle directive). In this example we must control the attributes ourselves for proper accessibility support.
If using v-model to set the visible state instead of the directive v-b-toggle, you will be required to, on the toggle element, add the aria-controls and other appropriate attributes and classes yourself.
When using accordion mode, make sure you place the trigger elements and components inside an element with role="tablist" and set role="tab" on each trigger element's container in order to help screen reader users navigate the accordion group. Unfortunately, BootstrapVue cannot apply those roles for you automatically, as it depends on your final document markup.
The salt-induced condensation of chromatin has been studied with flow-linear dichroism technique using an intercalative dye (methylene blue) to selectively monitor the linker orientation. At low ionic strength both linkers and chromatosomes (with their flat faces) are oriented preferentially parallel to the chromatin fibre axis. With increasing ionic strength both linkers and chromatosomes tilt successively towards a perpendicular orientation. Based on these results and structural considerations, an 'Accordion model' with a pentagonal nucleosomal arrangement is proposed for the salt-induced condensation of chromatin.
Series A10, A30, A40, & A50 air intake filters offer time honored protection for compressors, blowers, turbines, engines, and other air handling equipment. They are fabricated from heavy gauge enameled steel. Weather hoods on models A10 & A30 reject rain and snow. Any standard models can be modified at your request to more exactly fit your needs.
Male NPT (MT) or flat face flanges (FF) are std. Flanges match diameter & drilling for 150# ANSI standard. Specify optional right angle base (AF) for side mounts, (FT) for female NPT, (BE) for bevel or (PE) for square cut that match nominal pipe ODs, or (TE) for square cut that match actual tube ODs. Increased or decreased connections sizes are also op tional on any model.
Convert your 55-gallon drums into reusable, easy to clean containers. Vacuum-formed from 18 mil. thick low-density polyethylene, the FDA-approved accordion style liner adapts to the height of the drum and collapses easily for storage. This liner is sold in quantities of 15 per package with a weight of 30 lbs.
We receive inquiries nearly every day from people searching for information on an older accordion - usually either from a relative's estate, or that they bought from a yard sale, etc. We receive so many inquiries, in fact, that it's not possible to answer each one individually - so we direct inquiries to this article, which we hope will be helpful to those searching for information. There is also this Facebook group you can post in, and you may get some guidance from the accordion community.
You may have found our website after a fruitless internet search trying to find information on your accordion's brand name. Perhaps you're thinking you have a rare and valuable accordion because you can't find out anything about it - unfortunately, that's probably not the case. In the "Golden Age" of accordion manufacturing in Italy (the mid 1900s), there were literally hundreds of accordion companies and brand names making instruments. Though a handful of them are still in operation, most stopped manufacturing decades ago, and there is little historical information available about these companies. Your accordion may even have a serial number, but in most cases there are no records for tracking these numbers.
Some accordions were even manufactured without brand names, so that a retail shop could add their own name later when they offered it for sale. There are also quite a lot of these nameless instruments floating around out there, and there is no way to identify which company originally made them.
When it comes down to placing a value on an older accordion, the brand name often doesn't mean a whole lot anyway, except in a handful of cases. Appraising an accordion's value is not a straightforward process, because they generally do not have "Blue Book values" like many other instruments (such as guitars) do. Below, we offer some information to assist those who may be looking to sell their accordion.
Due to a current hefty stock, as of March 2022 we are not accepting additional 120-bass piano accordions for sale consideration. If you are within driving distance of our shop in Takoma Park, MD and have a piano accordion smaller than 120-bass, or a button accordion or concertina, you may email us photos and any information you know about your item. We will let you know if we're interested in having you bring in in for sale/trade/consignment consideration. We do not accept accordions for sale or consignment that would need to be shipped to us.
So - how much is your accordion worth? The short answer is, it's worth what someone is willing to pay for it. This could vary widely depending on where -- and by what method -- the accordion is being sold (by an individual on Craigslist or eBay, at a pawn shop or antique store, by a reputable accordion shop, and also by geographic region; the same instrument might fetch a higher price in New York City than it would in rural Arkansas). We always suggest taking a look on eBay (at current and "sold" listings) to see what a similar instrument is going for - and you will likely encounter a very wide price range. The "sold" listings will probably give you the most realistic figures. You can also take a look at our current used accordion listings for sale.
With older accordions, playing condition is the most important factor. Like cars, accordions need to have regular servicing every few years to remain in good condition. When they sit for decades unplayed - even in a case in a climate-controlled environment - the moving parts inside can tend to deteriorate, especially the leather, felt, glue and wax. Not all of these problems may be evident from the exterior condition or even a quick play-test. For an accurate evaluation, you really need to have an accordion repair expert open up the instrument and examine the interior. These folks can often be hard to find these days, so if you scroll further in this article, you'll find a guide to walk even a novice through checking out the condition of an accordion.
Repairs by a trained expert can end up being very costly if a complete overhaul is needed. This is why the potential value or selling price of an accordion is based largely on its playing condition, and what repairs it might need. Most of the used accordions that we sell have had some type of repairs done before they go up for sale.
We also look at the features a particular accordion has. There are numbers of bass buttons: 120 is the most common and considered "full size," although there are different sizes within this designation. An interesting phenomenon is that in recent years, people have been tending to want to trade their larger and heavier 120-bass accordions for smaller, more manageable sizes. So we have found that the selling prices of even professional-model 120-bass accordions have gone down recently, as they are tending to be less desirable.
Another important feature is how many treble reed banks the accordion has. You can determine this by looking at the switches located above the treble keyboard. If there are only 2-4 switches, the accordion probably has two treble reed banks (most commonly a Low and a Middle bank, or LM). The switches will also illustrate with lines or dots how many reed sets there are. Accordions with more switches may have 3-4 treble reed banks, perhaps Low-Middle-High (LMH) or Low-Middle-Middle (LMM), or LMMH. Accordions with two Middle banks are often referred to as having "Musette" tuning. The two middle banks are purposely tuned slightly "off" from each other to create a vibrato-type effect that can be desirable for certain types of music. The more reed banks an accordion has, the more professional a model it usually is - but this also usually means the accordion is larger and heavier, which again, may not be as desirable anymore.
