Fantastic synth and a really great company and customer service.

Spire, as many have already attested here, has a superb audio quality and is really efficient and resource friendly within users projects, allowing many instances of Spire to perform simultaneously with no drawbacks, even on older hardware.

Spire also now has one of the best preset menu user interfaces around and in my opinion is practically a perfect plugin at this point.

I must say that in my own personal experience, Reveal Sound's customer service has been excellent, and even very recently reinstated support for very old Intel CPUs which I am currently using in my device, which has allowed me to continue to use their product updates.

Overall, a fantastic product and company, that I will fully recommend to everybody, both now and in the future.

Spire is a top notch synth with more sonic flexibility than most! The only reasons I gave Spire 4 stars instead of 5 is that parts of the GUI are not as intuitive or user friendly as I would like, and I wish that the ENV1 and ENV2 ADSR graphics reflected parameter changes. Other than that, it's an amazing synth and if you're in the market for a new one, it's worth checking out.

Great Plugin but couldn't get it to work with FL studio 20.

Cant use it for everything, mainly only for leads and plucks because the sounds are so hard core but its what the market likes now, so highly recommended.

I have Spire for a while now, I have been sleeping for quite some time.

The installation was done without problems.

It is stable and does not crash Cubase Pro 9.5. CPU consumption is correct.

Recently, I started to work on a project that is close to my heart for several years and I reviewed all the synths I have in order to find THE sound I wanted, I stopped on Spire, I do not know by what miracle, he has the punch and sounds really REALLY good.

I have several hardware synths, I thought working on this project with the minibrute arturia, but in fact I think I'll record all this project with Spire.

This synth is well known musicians and he deserves it greatly.

The sound is incisive and powerful, its effects are good qualities.

I imagine that it can cover all kinds of electronic music.

It's a synth to have, each EDM musician must have it.

Finally after updating my PC from old amd core duo to quad core i5, I have the best VST synth i ever used.

Sounds excellent, but were it shines is the GUI. Cool skins, so easy to tweak, and just sexy as hell on my Dell high res screen.

Also good feeling when you saved a little, 20% and are 100% content with you purchase.

Get a kick out of the "Lets get ready to rock" message on init preset Lol.

If they add some neat like 3d wave table scan latest rage, Spire would be GOAT.

I want to give it 10, but will be reserved and say 9, just because it needs a few more customize sizes, say 130 or 140.

150 is a little big even on my 24 inch.
