Welcome to Oidos - yet another 4k/8k synth!

Oidos came into being around a year ago in connection with our Nexus 7 remake 8k intro Nexus 8. Its design is motivated by a desire to closely mimic the instruments from the original music.

Great thanks must go out to Revival for his insightful ideas about additive synthesis which led to the development of this synth.

I wanted to have the public version ready a couple of weeks ago, so people could use it for Revision 2017 productions. That didn't quite play out, but anyway here it is. Still half a week left to make something. ;)

The VST instrument currently requires a CPU with AVX support (around 2011 or newer). This requirement is probably going away at some point. The player code for inclusion in executables only requires SSE3.

It has so far been used in these productions:

Nexus 8
Exit Strategy
Uneven
Xanax
Vikanim
Uplifting
Bubble Trouble
FNTSTC
Serpent

Do try it out! And have fun! And come back here with comments/questions/suggestions/bugs/etc. :-D

What jazzcat said! And make it fit into the 256 byte cache.

On Win10:

When I try to make an easy_exe I get:

C:\dev\Oidos_2.0.0\easy_exe\temp>..\tools\nasmw -f win32 oidos.asm -o oidos.obj
oidos.asm:183: error: integer supplied to a DQ instruction
oidos.asm:183: error: integer supplied to a DQ instruction
oidos.asm:183: error: integer supplied to a DQ instruction
oidos.asm:183: error: integer supplied to a DQ instruction

and

Loading temp\oidos.obj...

C:\DEV\OIDOS_2.0.0\EASY_EXE\TEMP\OIDOS.OBJ: error LNK: Unsupported file type

Do love the sound and the parameters and the reverb though :)

Here's a quick test pattern I whipped up: http://vocaroo.com/i/s0Egdub81iBu

Visy: you'll simply need a newer nasm (ie been there done that)

Please tell me .. how is the OidosReverb.dll supposed to work?


I am also getting an error with the easy_exe, by the way:

Also 10/10 from my side I really love this synth! Thx for the seminar Punqtured and Blueberry! I also got the 32-bit version to work on Linux :-)

OidosReverb should show up in the effect list in the lower-left corner (under Track DSPs in Renoise 2). The parameters are described in the readme. :)

Could be the same error as visy is seeing, though that will only show up if you use reverb (which, judging by your previous question, I am guessing you are not). Is there an error from nasm further up in the text (right after the "nasmw -f win32 oidos.asm -o oidos.obj" line)?

The GitHub version of oidos.asm already contains a fix for that issue, btw. I will make a new release soon with that fix, support for non-AVX CPUs, plus maybe some other small fixes.

Cool, I have a working VST version for MacOS \o/

But I had to use the rusty "additive_core()" since the nasm sse and avx version crashes with bad access. (Either a pb of calling convention, or the fact i had to toy with the section declaration and naming convention to get the assembly to compile.)

Nice! Thanks for looking into it!

It is most definitely a matter of calling convention, as this differs significantly between platforms. I am about to take a closer look at that. At least Linux and Mac should be the same. :)

The non-vectorized additive_core() is significantly slower than the vectorized versions (at least ten times slower than the AVX version, judging by the Renoise CPU meter). So it is fine for testing that things work, but probably quite cumbersome to use in practice.

In the Windows VSTs, there are some accidental imports from the Visual Studio runtime DLLs, which cause the VSTs to fail loading on some Windows 7 installations. This can be remedied by linking statically to the C runtime. This feature currently requires nightly Rust, but it is supposed to be included in Rust 1.17 coming out next week. Will be fixed in the next Oidos release in any case.
