There is a basic version of the software, and then there is another version someone improved.

Then you need the SalamanderGrandPiano files. This is 1.1gb and the 'Adapted' version is like 145mb (but you can't really get good volume differences with it).

SAMPLERBOX IMPROVEMENTS

• little delay when scrolling between programs so you don't have to load each program but can seek for the program you want
• another text file, config-custom.txt with fields user can just modify easily. For example, user wants to set another button/dial to be for scrolling between programs (maybe his controller doesn't have a ‘program’ button. So he just enters ‘pin2’ or whatever the appropriate thing is in the field. Oops, it's not pin2. He enters pin3 and the button/dial on his controller works.

SamplerBox

• Version for Pimoroni PirateAudio video: https://www.youtube.com/watch?v=3Ak2o5ZDI9I&t=139s
• https://homspace.nl/samplerbox/downloads/ and download the .zip file (ISO file) and write it to a microSD.
• Then go to http://chromakinetics.com/samplerbox/build.html (instructions are also on this page to install)
• and you copy 3 files over to the microSD.

Make samples

• https://www.samplerbox.org/article/howtocreateasampleset
• notes and midi note numbers
• https://www.inspiredacoustics.com/en/MIDI_note_numbers_and_center_frequencies
• C3 is 48
• C4 (middle C) is 60

1. 1.Set up rPi with RTOS (FreeRTOS or Zephyr
2. →https://www.freertos.org/ download and extract
3. -Build by running
4. -Install the FreeRTOS library with
5. -add theh FreeRTOS library with <#include “FreeRTOS.h”>
6. -link project against the FreeRTOS library by adding this flag to your compiler command <-lfreertos>
7. -Set up your project to use the FreeRTOS API by follwing the instructions in the FreeRTOS documentation (this will involve creating tasks, setting up queues and semaphores, and using FreeRTOS API to control the behaviour of your tasks
8. 2.Install software sampler that is compatible with the RTOS
9. 3.Create sample library of 4 velocities
10. 4.Configure software sampler to use the sample library, and set it up to receive midi input

Nope. Maybe works but not worth the hassle maybe.

• Lubuntu fails to launch Prusa (just spash screen)
• Kali can't connect to the internet
• Ubuntu Studio doesn't allow AppImages to run (even with chmod, and even with fuse and fuselibrary2 or whatever)
• Mint is Ubuntu-based, so no.
• Archlinux is hard to install
• Manjaro is based on arch, so try it.

Casting Metal in Molds

• plaster for silver (both fine and sterling), ceramic for bronze, sand for iron, and selastic rubber for pewter. There's no issues with pouring metal into plaster,
• Plaster does not melt; nor does ceramic, and sand is fine at the temperatures used for cast iron. Similarly, selastic is temperature resistant to a certain level, and pewter melts at a comparatively low temperature, so it won't melt in that case.

microwave melting -- there are inexpensive microwave kilns that will melt small amounts ("jewelry" quantities) of many metals.

SAND

Aquarium sand from a pet store is very find (or play sand but you have to sift it)

Kitty Litter (clay)

• 95% or 90% sand with the clay, by weight
• plastic bag and pound with a hammer, sift out the fine stuff (powdered sugar consistency)

add WATER

• so it's moist not wet, use a spray bottle
• consistency where it'd be great to make sand castles

---

GLASS

• soda lime glass at 2200degrees
• mold is closed to keep it hot and then opened when blower nears

---

CNC mold from 3d files

• Step Files or IGS is the format to send someone, not STL, so they can make a file to cut a mold.
• (STLs don't have curves, they're huge in filesize (means you have to scale it again when you open it)

INVESTMENT CASTING

• zircon or other very fine ceramic slurry
• colloida-cilica binder and few cilica flowers is the liquid, water based
• dries for up to 3 hours (2 to 3 degrees f)
• 7 or 8 times
• and a final 24 hour dry just to make sure
• 68 degrees and then heated to melt the wax (they cool it to shrink so when it expands we dont crack the shell
• half hour to an hour at 200 degrees
• melt steel at 3000 degrees into oven at 1800 degrees and pour it into the (still hot) shell
• they buy stamping scrap, washed

Glaze

• cilica, alumina, and some kind of flux, alongside pacifiers, colorants, whatever, feldspar, nephilim cyanide,
• red iron oxide (deep green after gas-fired kiln in reduction atmosphere. If in oxidized atmos, putrid yellow

SILVER

• 28.35 grams in an ounce
• a typical gold ring might be 3-7 grams
• $20 per ounce of silver
• $5 or so dollars to make a ring of silver
