VCV rack plugin

NauModular VCV plugin

This is my personal collection of modules for VCV Rack: feel free to use them and modify them as you wish. If you find them useful, feel free to get me a beer.

Perlin

Perlin is a Perlin noise generator.

The speed knob controls how much nervous the noise is. On its side you have a CV control input and a smaller knob to balance the final speed between the main knob's value and the CV input.

The amp knob controls noise amplitude. On its side threre's a CV control input and a balancing knob, just like for the speed control.

The lower 4 knobs are a frequency mixer: the module constantly calculates 4 noise octaves and each of these knobs controls how much of a specific octaves goes into the final mix.

The 4 outputs positioned in a square shape are single octave outputs; they are in the same order as the frequency mixer knobs: the top left one outputs the slowest noise, the bottom right one outputs the fastest noise.

The lowest, central output is the mix output, giving you a mix of the noise octaves based on your frequency mixer settings.

S&H(it)

S&H(it) is a sample and hold module. The time knob controls how often it samples the input signal; the divider knob scales the other knob's value, so yu can range from very quick lo-fi sampling to >1s periods.

---

BitHammer

BitHammer is a logic module performing bitwise operations on 2 inputs. The incoming values are rendered as bits, hammered, reassembled as virtual voltages and finally sent out to the 6 outputs.

---

Tension

Tension is a fixed voltage generator: you turn the knob, you change the voltage. Useful when playing with logic chains or if you need to power up a virtual lamp ;) .

---

Function

Function is a function generator; it outputs the 3 conic section functions you learned in high school: ellipse, parabola and hyperbola. Input voltage acts as the x variable, while the knob is a constant parameter.

naumodular's Issues

Windows binaries here (v0.5.2)

Hi,
Here you can find the compiled version for Windows platform (for your releases repo).
Regards.

NauModular-0.5.2-win.zip

Fix versioning to be accepted into the Rack community repository

Rack v0.5.1 will include a plugin manager, and plugins need to follow the versioning guidelines in order to be accepted. You can use this example plugin Makefile and Tutorial.cpp file as a reference for making sure the version is the same in the C++, Makefile, and JSON manifest.

• Your plugin is versioned as v1.0. This needs to be v0.5.something.

Once you've fixed this, send a PR to the Rack community repository and remove the "disabled" property in the JSON manifest file.

Use ARCH_* for architecture detection

NauModular/src/NauModular.hpp

Line 3 in c7680cd

#if (defined(__APPLE__) && defined(__MACH__))

The Rack way of doing the above is simply

#ifdef ARCH_LIN
...
#ifdef ARCH_MAC
...
#ifdef ARCH_WIN

because the Makefile system passes these defines as flags to the compiler.

compile error (linux)

With master at c7680cd I get

src/Osc.cpp:209:26: error: ‘memset’ was not declared in this scope
     memset(_buf,0,_bufLen);
                          ^
src/Osc.cpp:210:49: error: ‘strlen’ was not declared in this scope
     uint32_t ii = (uint32_t)strlen(_addr.c_str());
                                                 ^

Including <string.h> appears to it fix for me, for example:

diff --git a/src/NauModular.hpp b/src/NauModular.hpp
index 6a20010..7691b83 100644
--- a/src/NauModular.hpp

 #include <mach/clock_types.h>

 using namespace rack;
 
 extern Plugin * plugin;

Not a linux cpp pro, so not sure how generically useful this info is - hope it's some use! :)

Here is a windows build. I had to change abs() to fabs() in Tension.cpp

NauModular.zip

when speed knob is turned down the output value doesn't change

I was trying to get a real smooth slow lfo going but it doesn't seem to slow down enough. It seems to just stop. And then it gets worse over time. It will stop at a higher and higher value. Maybe related to that other issue #3

[bug] Perlin: output mutes after a while.

OS: win
Rack: dev
Plugins: dev

somehow the module just goes mute after a while and i can't turn it back on with any of the controls.
also tried the menu options initialize and randomize.
i have to delete the module and load a fresh instance.

great module ideas btw, thx so much.

v0.5.2 (BitHammer, Function): huge voltages issues.

Platform: Windows 7 Pro SP1 x64 (French localized).
VCV Rack v0.5.1 (not dev).
NauModular v0.5.2.

Hello, firstly, thank you very much about your NauModular modules. ;)

However, I report huge voltages issues, concerning BitHammer and Function modules.

I've recorder & posted a (non-indexed) video on YouTube (2 min), showing the voltage issues on these modules. Also, I precise the oscillators I've used, TinySine and TinySawish (both by AS) deliver voltages into range -/+5 V.

Of course it's possible I'm wrong somewhere about voltage measurements, by using Fundamental's Scope.

Perhaps you'll must add a "voltage limitation" in code (for future release) to stay in range -/+12 V (in my opinion).

Link to YT video: here
(please advise me when you have seen it, btw I'll remove it, thanks in advance).

Regards.
Dominique Camus.

VERSION update in Makefile

The VERSION needs to be updated in the Makefile to 0.6.0, no dev suffix. Thank you!

Perlin noise produced by the module seems to be a repeating pattern

The Perlin noise generator is always producing the same pattern.
To reproduce : record the output and have a look to the signal, you'll see a single pattern being repeated.

Some ideas to correct this faulty behavior can perhaps be found here in this very short c++ Perlin implementation (I have not tested this code, just an idea to fix the Perlin generator) :
https://github.com/Reputeless/PerlinNoise/blob/master/PerlinNoise.hpp

Osc.cpp: includes not working on windows

getting compiler errors for:
arpa/inet.h
and
sys/select.h

first answer on the search said to use Winsock2.h instead, but that doesn't cut it.

Version 1.0

Your plugin is not compatible any longer with the current version of VCV Rack. Are you planning on updating it and releasing a new version?

No docs for the OSC module

I noticed it opens network ports and I was wondering why.

Linux Release

Please can we have a Linux release?

plugin manager

Hi!

I m helping Andrew with the plugin manager. I went throu all the module packs today and saw that you only provide Mac binaries. I wanted to know if you need someone to compile your modules for Windows and Linux? Because people like me can´t use your modules unless I compile them myself. Not everyone knows how to do that.

Perlin: hitting float limit causes constant output

After letting the Perlin module run for a while the curTime variable (a float) if "full" hitting the float limit and adding deltaTime to it does not have any effect anymore, hence producing a constant output.
