Well, I absolutely appreciate the feedback! I may well return the favor this upcoming Ludum Dare :)
Warning: lots of info regarding Ludum Dare music and sound incoming!
The DAW I used for this game is Reaper, which is nice because it is cheap and not a subscription fee -- overall very nice IMO. However, I used to use LMMS, which is completely free, for Ludum Dare music. It's honestly in some ways easier to use than Reaper, and I don't do anything with Reaper that is that different from my LMMS work.
Besides the DAW itself, I used a handful of virtual instruments:
- The drums are from Spitfire LABS -- which is a collection of free virtual instruments from Spitfire Audio/
- The bass guitar is Ample Bass P Lite II, which is free and honestly is one of my favorites--it has actually inspired me to start learning the bass guitar!
- The piano is Spitfire's "Felt Piano," which I got because it was apparently used in Celeste's soundtrack.
- The synth parts are done with Matt Tytel's Helm, which is a nice synthesizer. He also makes Vital which is pretty neat as well.
- The strings are another Spitfire LABS instrument.
But, I have made music a whole bunch of ways over the past few years doing Ludum Dare.
One thing I used to use a lot of was SoundFonts. I believe they're basically an old, somewhat standardized sampler format, or something. But, the basic idea is, you can download a big SoundFont pack that has like a hundred different instrument sounds in it, and at least to my untrained ears they all tend to sound nice. They're a nice way to quickly get a lot of options for acoustic-sounding virtual instruments without researching in-depth a bunch of specific plugins; you just have one plugin that plays SoundFont files and then you can browse through the SoundFonts you downloaded and see if any of them sound right for whatever you're doing. (I have been considering getting back into SoundFonts myself, but they are actually harder to use in Reaper than in LMMS...!)
Also, a nice DAW-less way to make Ludum Dare music is through beepbox.co. It's a great tool, very easy to just dive in and start making music with, all you really need is a mouse and some speakers. The last time I used Beepbox for Ludum Dare music was Ludum Dare 45. It's definitely one of my favorite tools, even if I haven't used it in a while.
(And, speaking of classic Ludum Dare sound tools -- maybe you've heard of sfxr and bfxr and the chiptune sounds they can generate. One more tool I can recommend in that genre is sfxia, which is unfortunately kind of obscure but is great at making clicky sounds IMO)
Well, hopefully some of that information is useful. I'm not sure quite where you're coming from, maybe you already have a DAW you're very comfortable with, and all. But, now you know what I use!
Anyways, good luck with your first Ludum Dare! 😄
