You can now also follow me at mastodon.rosseaux.com/web/@b… resp. @[email protected] . But I myself will continue to stay on Twitter as well, Mastodon I will just have in addition for those who want to leave Twitter but at the same time continue to follow me. So don't worry 😀
Rush E on a physically modelled concert grand piano in klangknecht, my own (still unreleased) #DAW.
No samples: waveguide strings, felt hammer, dampers, half-pedaling, sympathetic resonance, modal soundboard, all in real time.

SEEDS - Echoes Beneath the Sands is now on Steam and you can wishlist it!🌱
Terraform a barren planet back to life. Powered by PasVulkan, my own #Vulkan engine written in #ObjectPascal. Over 2 million lines of code in total.

I'm looking for remote client work to bridge the gap until my game project generates revenue. If you know of any opportunities in software dev (Pascal, C/C++, x86 ASM, Vulkan/GFX, engines, compilers), music production, or similar fields, please reach out! rosseaux.com/
"Time", a WIP test track for new BeRoTracker features:
- Pattern Matrix: the whole song at a glance
- Channel Patterns: write a part once, reuse it anywhere
- OPL3 FM synthesis next to samples, in the same patterns

#BeRoTracker #OPL3 #tracker
New in BeRoTracker: channel patterns. A single channel of a pattern can point at a separate one-channel pattern, usable in any number of patterns. Loop or one-shot per use, own loop length, own start row. New Pattern Matrix page shows all of it.

BeRoTracker 1.00.2026.09.15
TL;DR: Now also with a macOS build.
Now with an RHI impl., so it can also use Vulkan and Metal for rendering, no longer OpenGL-only. This means it can now also run on AArch64 macOS, alongside x86-64 Windows and Linux.

BeRoTracker 1.00.2026.09.11
New third F12 page: Playback Compatibility. Every tracker quirk the replay goes by, as 159 named switches and 7 family fields, in plain sentences instead of source identifiers. Editable in .brt, read-only for MOD/S3M/XM/IT.

New BeRoTracker build out: berotracker.com/ - samples, VST2/VST3/CLAP, Buzz-style modular, MIDI, AdLib FM, automation, all in one #tracker. Plays 447/450 AT2 modules with register-identical OPL3 output. 42 AdLib formats import. Win/Linux, X11/Wayland, no SDL.
New video: the current state of KRAFT, my open source Object #Pascal 3D physics engine. Now with signed distance field collisions (even heightfield terrain), plus ragdolls, joints, vehicles & more.

Guest Software rendered OpenGL kmscube running on a guest 64-bit RISCV Alpine Linux system in my PasRISCV emulator with active x86-64 Tracing JIT Dynarec compiler with smooth >= 60FPS 🙂 #RISCV #Emulation #JIT
The irony: the entire #RISCV base ISA (RV64GC) is beautifully RISC: simple opcodes, fixed 32-bit instructions (+ compressed), load/store architecture, no flags, no implicit state. Then RVV comes along and throws all those principles out the window: global implicit state, (1/5)
extremely complex "super-SIMD" that is difficult to efficiently map in a JIT. A more traditional SIMD extension with fixed vector widths and clearly defined instruction semantics would have been much more JIT-friendly. The upcoming P extension does go in that direction, (4/5)
A small rant about vector extensions in RISC-V, although I like RISC-V in general. But why is RISC-V's vector extension (RVV) so different from other SIMD instruction sets like x86's SSE/AVX or ARM's NEON? It seems like RVV is designed to be more flexible and scalable, (1/3)
but it also makes it more complex and harder to implement a JIT compiler for it in my PasRISCV emulator, where the JIted code needs often to bailout to the interpreter for non-native-SIMDizable code cases. I hope that the RISC-V foundation can come up with a more clean and (2/3)
