Spire

Great sound engine. Not the greatest work flow. They need an update to bring the GUI into the future. The UX design of the mid 2020s is leaps and bounds beyond what was fashionable when this came out (just look at things like Gullfoss and the new Serum). It definitely sounds very Virus-y and has some tasty presets, but it needs a visual overhaul. It's more of a preset player for me, because it's just never all that clear what is going on. Make it more fun and inviting to play, and you'll attract a whole new generation of enthusiasts. I love the AI preset feature. Now that's more like it. Bring this thing into the future.

This is one of the VST plugins that inspires me right from the start.
When I hear how it sounds, I just want to start making music. Even the init preset sounds nice, but when I tried various beautifully crafted presets, I couldn't believe I got that sound! I regret I didn't try it earlier in favor of native Linux VST plugins.
Even the process of selecting presets or creating my own is really pleasing.

Really great synth with lovely sounding oscillators, great detune, nice GUI and many different filters.

Probably the synth I use the most, so versatile, with amazing sounding presets, spoilt for choice.

If you are into any electronic type of music production and beyond, this is the one.
Listen to the pro presets, and you will be amazed at the quality and what is possible!
Cannot recommend it enough.

Good synth, nice GUI, good sound, easy to work with. Its famous synth for dance music from the past. I don't think its good buy today because for same money we can get better synth. Synth is just a basic one It needs to be modernised to stay competitive adding missing stuff like layers, sample oscillator and better ARP (16 steps only, no step gate).

There are lot of presets and sound packs for Spire. Buy Spire only if you are interested in these presets, otherwise let it die, authors are doing just tiny bugfixes over years. Don't give them your money, they are just sound pack resellers now.
