CDFhorn has added a number of mouthpieces to the Database.

https://www.horn-u-copia.net/mouthpieces/index.php

Additionally, I have modified the display so the user can select either the maker, the instrument, or both.

As recommended, many of the new pieces were scanned by Vennture and can be seen at https://trumpet.cloud/mpc - both tracings and even info pages in some cases, plus a new-and-improved spec sheet section with detailed measurements from VennCAD

Some new features at https://trumpet.cloud/mpc/ -
Now it's more like Brass.cloud, since they've decided to expand to include the entire range of brass mouthpieces!

They have alto/tenor horn, mellophone, French horn, trombone, and tuba mouthpieces now [the ones from VennCAD, pending future submissions]. The drop-down in the upper-left-hand corner [likely says "Full Mode" - next to CVD Mode] lets you choose the general family of instruments, based on your instrument area [Bass, Bone, Horn, etc].

Metrics/specs are available in a table page, versus just PDF & Excel - https://trumpet.cloud/mpc/specs/sheet/ - so now you can see diameters, depths, shank sizes, etc online.

You can also set up a semi-custom graph comparing two data items [default is set to compare Cup Diameter to Cup Volume, but you can choose two metrics, then highlight three individual mouthpieces].

I'm not a site sponsor - just a contributor - but these updates make the site much more useful to brasswind players in general!
