Anyway I spent the time and I got my Arturia Keystep to play MIDI through the raspberry pi using #fluidsynth!

If you zoom in you can see the exceedingly dusty raspberry pi.

Next steps are me doing research into USB audio sound cards for the pi, as well as headless control options.

I want time to think about the control options, so I don’t know when I’ll be doing another update. MIDI on pi is very idiosyncratic and confusing.

Today: FluidSynth Reverb and Chorus

Due to the introduction of mixer-level reverb and chorus effects, the FluidSynth reverb and chorus config parameters have been renamed to fsynth_reverb and fsynth_chorus, respectively.
To maintain backward compatibility with existing configurations, the FluidSynth reverb and chorus effects are enabled by default, so all your SoundFonts will sound just like in previous DOSBox versions. If you enable the mixer-level reverb (or chorus) as well (e.g. by putting reverb = on in the [mixer] section), you would get a second round of reverb (or chorus) processing on the FluidSynth output. This is by design as it allows users the greatest level of control over customising SoundFonts (e.g. some would sound best with the FluidSynth reverb only, some with both, etc.)

Note
In the SF2 format the reverb and chorus amounts are specified on a per-instrument basis, while the mixer-level effects are applied “globally” to all instruments in the summed FluidSynth output. Therefore, what works best really depends on the particular SoundFont in question and on individual user preference (see this discussion for further technical details).

Today: Configuring MIDI device

DOSBox Staging supports the following MIDI devices for music playback:

-System/Host MIDI (default)
-FluidSynth for using SoundFonts
-mt32emu/MUNT for emulating Roland MT-32, CM-32L and LAPC-I synthesizer modules.

I have several old ONScripter-EN and KiriKiri visual novels that use MIDI files for sound. I thought I had resolved my difficulties on Linux, but I had an issue where sound would work running the games under WINE but not when running the native Linux versions of ONScripter-EN games (note the KiriKiri games have no Linux version). Back into the Arch Wiki I went... I eventually resolved the issue with a proper Fluidsynth configuration and loading three kernel modules. This is the long saga (note I did this on EndeavourOS, but the issues should be generally applicable for those of you interested in the issue on Linux).

(Note all of these steps are in the Arch Wiki. To the extent this is a "guide" -- consider it one only in that I highlight an issue and point people to where I found the solution.)

The New Leaf JournalMIDI sound for games on Arch-based distroHow I followed the Arch Wiki to get sound on ONScripter-EN visual novels using MIDI to play when running the native Linux versions of the games.

Some fun progress today.

I got an older Raspberry Pi operational with the Bullseye version of the Raspbian OS, then successfully got #FluidSynth installed and running with a #MIDI keyboard.

Impressive sound - can certainly do something with that.

Contemplating the obvious: a standalone box to work with keyboard as a digital piano, with just on/off control req'd to work. ie no console interaction.

Surely someone else has already done that, no? Must search a bit, I guess.

Continued thread

My intent after upgrading my older RPi board is to install #FluidSynth which sounds like it will provide digital synth sounds for a MIDI keyboard.

Hoping this decouples a keyboard from my laptop for a more portable electric piano use around the house. Then I won't be hogging it as much.

Which packages are the 5% missing on #RISCV, what efforts are currently made and what need to be done:
https://lists.riscv.org/g/software/message/174

I would add after 1 or 2 weeks of testing that, Most JIT are missing, not only Lua (there is already a patch for RV32), PCRE, php engine, mb_strings (but they can all be used without it).

Other missing libs: libgsl25 (GNU Scientific Library), needed by Hugin, and Darktable (there is still rawtherapee). #ObsStudio is missing too.

On the sound design part, SuperCollider is missing.

On the (retrocomputer/arcade/console) emulator side missing are: openmsx, but mame, libretro (including bsnes, beetle-psx/vb/pce, desmume, etc...) are here. Missing in libretro are snes9x, and nestopia (closed source)

Qsynth is a fluidsynth GUI front-end application written in C++ around the Qt framework using Qt Designer. Eventually it may evolve into a softsynth management application allowing the user to control and manage a variety of command line softsynth but for the moment it wraps the excellent FluidSynth. FluidSynth is a command line software synthesiser based on the Soundfont specification.

Tip for anyone composing in #Frescobaldi:

If you want to use MIDI input but get errors about an "invalid running status" when you attach a physical MIDI instrument, your instrument or interface may be generating SysEx messages that Frescobaldi can't understand. To work around this, you can use an app like #VMPK - in VMPK's "Connections" menu, set the input to your MIDI hardware; and in Frescobaldi's "Preferences" dialogue, set the input to VMPK. This makes your instrument change the internal state of VMPK's keyboard, and VMPK then generates appropriate MIDI events reflecting those changes. Since it's tolerant of SysEx messages in its input but won't generate them in its output, this effectively filters the stream to make it safe for Frescobaldi to consume.

As a bonus, you can see the keys light up on the VMPK interface to reflect the notes currently sounding, which may be more intuitive than reading the #Lilypond source Frescobaldi generates. If you also set something like #FluidSynth as the output in the "Connections" menu, you'll be able to hear what you're playing, too.

Learned again some more about #OpenRC under #Hyperbola. No MIDI-Output for the classic game "WarCraft: Orcs and Humans" and I had question marks above my head what to do. But hey: The Wiki of #Arch-Linux is the way to go for more and so I had a look onto how loading kernel-modules at runtime (https://wiki.archlinux.org/index.php/Kernel_module).

But this was working other way because of the init-system: "snd-seq" and more modules were not loaded because of #OpenRC as init-system. So a look onto #Gentoo (https://wiki.gentoo.org/wiki/Kernel_Modules). Guess what? The modules are loaded now and I have access to MIDI-funcationalities with #Timidity and #FluidSynth. #Free-and-Libre #GNU-Linux
