osc | Outil de suivi des Contrats / Outil de suivi des Budgets

What I try to do: I want to write a Python program running on an RPI which communicates to a software called QLab4 via OSC. It should display the received workspace data (JSON format) in a table, while the user is able to select a cue from the table and fire it using a key press.

So far I got two scripts (just proof of concept stage), but I struggle to combine them into one program. Any hints to how to do it would be greatly appreciated.

Script 1: Starts OSC client & server and sends and receives OSC to/from QLAB. At the moment it just prints out the JSON (workspace) and the selected cue.

I'm new to AudioKit and am using v5. The oscillator frequency ramp doesn't seem to work as expected. The following example has 2 successive ramps. First it ramps 440-880, but then sounds like it goes 880-660 instead of 440-660.

If I comment out osc.$frequency.ramp(to: 660.0, duration: 1.0), it ramps 440-880, then ramps extremely quickly to 440 but gets there.

Seems like something isn't resetting after the ramp.

(The sleeps are only for testing.)

Is this a bug? Is there something else I should be doing? Any insight would be much appreciated! Thanks!

After realizing it is nearly impossible to find help on getting keybindings to work with the C plugin in MPV (Possible to allow key bindings with MPV C API when no video (GUI) is being shown?), I decided to learn some Lua to help with the cause. Problem is, the docs aren't very clear on how to add Lua scripts with the C plugin, what I could find out was that check_error(mpv_set_option_string(ctx, "load-scripts", "yes")); should be called before initializing mpv in the C plugin, which points out that there should be a way to add scripts... When loading a script in the terminal you can do mpv video.mp4 --scripts="script_name.lua" and that will call the script from inside $HOME/.config/mpv... How do I achieve the calling of Lua scripts in the C plugin for MPV? I tried a few things including check_error(mpv_set_option_string(ctx, "scripts", "test.lua")); and check_error(mpv_set_property_string(ctx, "scripts", "test.lua")); and const char *cmd2[] = {"scripts", "test.lua", NULL}; check_error(mpv_command(ctx, cmd2));, none of which worked...

How do I call a Lua script for MPV from the C Plugin?

Below is the code I'm using to test things out:

I want to show the value of a 0 or 1 array on a plot with other timeseries.

How can I achieve something like the grey lines below - except mine will oscillate a lot more.

For example, how to add osc here:

Trying in JS to create a single oscillator, with a smooth, non-clicking frequency tone that rapidly turns on and off. Timing for web audio discussed by [Chris Wallace][1]. A timing scheduler can be found by [Aqilah Misuary][2]. This example produces a correct-sounding tone based on the frequency. However, a noticeable click is present. Fixing clicks has been addressed by a posting on [Stack Overflow][3].

First code snippet is based on the Code Pen version (see link 2), changing frequency to 432 Hz.

Second code snippet: Adapted JS (see links 2 and 3) from these resources, adding ramping, using the 432 Hz frequency,I can get the clicking to stop, but my frequency sound is now blunted, no longer has the correct 432 Hz frequency sound. I suspect that I am doing something wrong, not using the timing or settings correctly. I've tried various timings and settings and even "initial" instead of "exponential" ramping, but none have fixed the issue: clicking gone but frequency sound is now blunted, doesn't retain the correct sound based on the frequency chosen and that would be heard if ramping is not used, leaving the clicking. I must be doing something wrong?

Any way to fix the clicking without blunting the sound? [1]: https://www.html5rocks.com/en/tutorials/audio/scheduling/ [2]: https://codepen.io/aqilahmisuary/pen/ONEKVM [3]: Web audio "Click" sound even when using exponentialRampToValueAtTime

in my OpenStack setup I have one tenant with different projects and I'm trying to figure out what would be the best approach to make communication between the subnets 10.200.0.0/24 <-> 10.202.1.0/24 of two projects possible (see picture below).

Would that be by creating a shared network and connect GW01 and GW02 to it with static routes? or is there a thing such as "shared router"?

I am a bit lost in the endless possibilities of OpenStack and would appreciate any help/hints.

I am using a Ricoh Theta Z1 updated to the most recent firmware (1.60.1). I am trying to debug an Android application, but I found that one of our commands was repeatedly failing, so I connected to the camera directly from my dev box and tested the protocol directly via curl.

It's my understanding from the documentation that this command should work:

I am trying to make a FXB file previewer (VST preset banks for those who don't know) for Sylenth1 banks. I have encoded the FXB as an ASCII string and had it print to the console. The preset names show up fine. My issue is that the parameters for the oscillators, filters and effects are encoded as random characters (mainly "?" and fairly big spaces).

Underlined in red: file header (?)

Underlined in blue: preset name (which I want to keep)

Underlined in yellow: osc/FX/filter parameters (which I want to discard from the string)

Here's the code I wrote:

I am trying to communicate with a LeCroy WaveRunner 640Zi oscilloscope from a Raspberry Pi, they are connected with a USB cable. I have already done this under Windows, but now I am not able to make it work in Linux.

If I run lsusb I see this:
