7th July 2024

July's word for the 7th is Echo. (Echo!)

-=-=-

JSE has some nice Echo functions, which make use of Javascript's ability to use some "impulse" sounds to generate echos and such.
As I started to fiddle about with sounds and echos and impulses, too, something else popped into my head.

What if I made a little keyboard to play all of the sounds with!?
So that's what I did.

You can Play with the Keyboard in JSE.

It took a while to get the keyboard looking right. I tried to make it so that tapping keys would do what they're supposed to do.
Then I set a slider of sorts to choose from all the echo styles, and then I added all the little sounds that sounded decent, when played upon the keyboard.

After that, I had to add all of the frequencies, so headed back in time to where I knew they all lived happily.

I grabbed the Amstrad CPC 6128 manual, and flicked to Chapter 7, Page 25.
On there are a super handy selection of Notes and Frequencies, which I typically tend to return to whenever I need them.

I popped them into the engine, and added tapping functionality to the keys, and.
That was pretty much it!

I had to add touch testing, so that "chords" of a sort could be played, and then I went through all the instruments to tune them as best as I could.
It's nowhere near perfect, but it is fun to play with for a little bit.

Best played on a touchscreen device, so you can tap a little better!
