Now that our game's out, I can show off Metron Tracker running on Quest (ARM) in #UnrealEngine 5! Late in dev I whipped up a pattern/VU-meter display in UMG as a backdrop for the intro, so you can see the sample & synth notes being played in realtime. CPU usage is pretty minimal

Never flung money at anything so fast. Absynth 6! And it's backwards compatible with 20 years' worth of my nonsense! Thanks for the heads-up, @pkirn.bsky.social

Wish it could bulk import said nonsense though. Also some knobs are vertical mouse drag while others are horizontal 🙃Stay weird, Absynth

My actual day job (one of them, anyway) is to compose 90s atmospheric drum and bass, in the custom tracker wot I wrote, for a video game. The game responds to the music data and vice versa. In 1994 I hoped I’d get a job doing this on the Amiga when I grew up - close enough.

#gameaudio #demoscene

Metron Tracker standalone is a feature-complete 2.4MB exe! This example song is 2.6MB on disk and its memory footprint is 3.7MB. Playback averages 2% of audio CPU budget.

That leaves me ~4GB and 98% CPU to spend on ambient fart emitters with convolution verb

#UnrealEngine #middleware #gameaudio

Wrote a new sample loader for Metron standalone so all the oldskool tracker commands are back! No DSP effects here, just sample manipulation - very cheap on CPU. Multisample instruments at diff octaves played randomly, but all share 1 buffer in mem.

I rewrote my #unrealengine tracker in raw C++ so it’s a 3.5 megabyte exe instead of a 35GB engine/project. This is a core player engine with a Win32 wrapper and a UE plugin wrapper. Testing with my hybrid FM/phase distortion synth and waveform blending LFO, and my cheesy-but-cheap reverb algo

I wrote a combined sample reverse & pitchslide up/down command for my #UnrealEngine runtime tracker! (also optimised everything to hell - this tune inc DSP FX uses ~2% of my CPU budget and a ~500kb memory footprint - but who cares, jungle reeewind spinback is what I'm excited about) #gameaudio

A glimpse of my composing & mixing workflow in The Siege and The Sandfox. I tend to work at runtime with Metron Tracker & my mix system as #DearImGui overlays. I can override gameplay mix events or test in place, tweak synth/sample instruments, adjust quantised sync offsets #UnrealEngine #gameaudio

Our game is finally released today!
The Siege and The Sandfox is a 2D #metroidvania with gorgeous pixelart; stealth-based gameplay; and lots of dynamic music and game audio by meee.

#indiedev #gameaudio #unrealengine

More aggressive optimisations for my #UnrealEngine FM synth, which now has this beast of a LUT-based waveform blending LFO that can be cheaply mapped to per-operator params. It's 'only' 4-op, but all ops have feedback, multiple waveforms and can optionally use phase distortion

Wrote a custom LFO for my #UnrealEngine FM/phase distortion hybrid synth. It precalcs lookup tables to keep it cheap, and can blend two waveforms. This is triangle vs interpolated noise and looks nice and hairy on the scope. It’s just very slightly modulating the pitch of one operator. #gameaudio

The FM Synth in my #UnrealEngine tracker DAW plugin hasn't had much love for a while, so I added a phase distortion synthesis option to each FM operator. Sort of a hybrid of Yamaha-style FM via PM and Casio-style PD via...trial and error. Sounds ok! Just needs some modulation hookups.

#gameaudio

I wrote this effect for the NTS-3 Kaoss Pad using Korg’s open source Logue SDK. Cool, you’re thinking, they made it easy so everyone can get involved? No, of course they made it a total pain in the arse! But if you know some C and don't mind faffing about with weird toolchains it's fun.

I added an allpass filter to my #UnrealEngine Karplus-Strong synth with a random coefficient per note. It's everything I hoped for and more.

#gameaudio

I wrote a #Reaper script that explodes multichannel BWF items from my Sound Devices 633 to child tracks while preserving the metadata (it's discarded by default), muting the source, and appending item names with track names and circled state from SD's iXML tags. Niche but ninja. #locationsound
