Some remarks on MIDI stuff.

 Run Fluid-Synth.

>_  sudo fluidsynth --server --audio-driver=alsa -o audio.alsa.device=hw:0 /usr/share/sounds/sf2/FluidR3_GM.sf2

Run Timidity.

>_ sudo timidity -iA

Timidity vs Fluid-Synth.

In my case, Fluid-Synth works out of the box w/o extra efforts.


Whether real-time Linux kernel is worthy, huh?

Absolutely Nope: user-space is major provider of latencies.

What about Jack?  

Mostly useless too: theoretically it makes possible sophisticated rerouting of midi/audio ports, but in Practice, for simple/cheap systems, it just causes greater lags & extra load on cpu as well.. Professional sound-making studios are always the matter of hardware ;D

MIDI to WAV.

1stly, export or re-export midi from Rosegarden to set instruments in, then..

>_ sudo fluidsynth -F /tmp/Universum\ Vox.wav /usr/share/sounds/sf2/FluidR3_GM.sf2 /tmp/Universum\ Vox.mid

or 

>_ sudo timidity /tmp/Universum\ Vox.mid -Ow --output-stereo

Actually, TAM provides commands & subcommands: for shorter notation, c{...} is a command; s{...} is a subcommand + we have hotkeys {UpArrow}, {DownArrow}, {Insert} etc. If a context is known for sure - just use {...}. For instance, c{sieve ...} == {sieve ...}. The very P

 2023 08 15 1.7-17: now it's possible to rename files.. So, how to: ren <file index> <new name> press TAB to expand <file index> into full or short form - just type command "ren <file index>" and press TAB. Tip: press F12 to reset command line. 2023 08 17 1.7-23: makes possible to copy files ==>> cp <file index> <new name> Actually, "cp" command has the same routine as the "ren". PS.. keep in mind: this variant overwrites existing file silently. 2023 08 18 1.7-29: 'cp' command is safe. 2023 08 19 1.7-31: resolved sad problem w/ apostrophe in file names :) 2023 08 21 so far the're problem to search files with apostrophe in their names, thus we can use crutch-ish workaround: -in_name  'grep==-E  [^a-zA-Z.\d\s]s\s|[^a-zA-Z.\d\s]t\s' 2023 08 23 1.7-35: "rm  <file index>" to delete file. TIP: killed file gives "::D" mark in the table, otherwise a file wasn't removed.

/Key element of basic cyber security/

 So, let's take for model Windows + Router : our very goals have been... Protect ourselves from botnets & trojans. Teach Windows to behave not that bossy w/ its hidden activities & annoying updates. 1st of the all, we need to block direct access of Windows to Internet: it can be achieved w/ Router's Firewall (You can block/allow access by mac address + can change mac address of network card(s) in W10/11). 2nd step is, opt web proxy: it can be Router's Proxy / Linux machine in Your local network (for example, Squid proxy is rather good shot) / external VPN (then it takes to opt Router's Firewall additionally). It's obvious that Microsoft can easily bypass such protection, but here has been the juridical catch - they would have shot selves in their own feet, if they would have used trojan-like approaches in so open manner. There been very Law for big corporations... Any controversial/dirty practice must be either well-hidden or non-existed at all. However, som
