I know this was mentioned somewhere else in a different thread, but I think it can't hurt to have it in a thread on its own 😈

I'd like to have the option to use double precision floats. Not here or there, but through the whole shebang from primitives to code, from stream to float (hey, that rhymes!).

When I want speed, I use 32 bit floats. When I want precision, 64 bit.

I'm right now implementing at tube simulation, and it sucks (sound wise) a lot to have the 12AX7 characteristics computed with e=2,71828.

You have access to x86 assembly op codes already, & I requested 64bit SSE already.

Well, I didn't expect Double floates under the second thread title 😉

Anyway, good to hear that I'm not alone!

Same difference 🙂 The existing x86 commands have more precision if I remember correctly; 80bit vs 64bit. Good to resuggest anyhow; Live7 added a 64bit option to keep it from sounding too "digital". Live5 does have a distinct sound.

Also, I think most people can afford a cheap dual-core computer now; Dell sells them for $400 with monitor sometimes. Not to mention used P4 going for

00 So if someone can afford a
00+ programming software, they should beable to afford a SSE2 computer, thus handle 64bit double precision maths. If not, they can keep using Buzz.

Before your first post

A few rules keep this a friendly place. You agree to them once.

Shown next to what you post, here and in the app. It doesn’t have to be your real name: 3–24 lower-case letters, digits or _ (capitals become lower case, spaces become _).

    Then your post goes up straight away.

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
