I'd agree mate, It's one of my faves at the moment (that and the legendary Zebra of course).

I like the filters too, and I REALLY like the distortion FX. Be sweet when the Arp ans Stepper will be added.

Hi Theo, I'm on PC (S1, Win7 Pro x64, 8core XEON 2.83GHz) and xils V+ is killing my machine compared to Spire, too.

My *guess*: This has to do (obviously) with code optimization *and* which compiler has been used (Gnu/Intel) and compiler settings. From what I read, the Intel compiler's result can speed up code up to 4 times faster compared to Gnu. Some clever coder to clarify, don't take my word for it.

I'm still considering purchasing Spire. I've demoed it in Reaper 64bit on Windows 7 and a 3 year old i7 processor. The cpu is higher than some, but not ridiculously so. I had no problems playing chords on any of the patches. I compared it to (quickly) to Fusor and it was very similar in cpu usage, usually somewhere around 5% registering in Reaper. One pad preset did get up to 7%, but everything else was mostly around 5%. The only problem I've ever had with a synth was Lush. When I demoed that, I got some bad crackles when playing chords. There are a lot of factors that can cause cpu issues as there are so many different set-ups out there.

A pad I made in Spire.
10-note polyphony, some unison as well.
50% CPU-load on my old Core2Duo

That's a lovely pad sound mate.

Is this only me who hears tiny crackles when the pad is modulating?
Is that normal?

Thanks!

There will be a bank but not soonish. I want v1.0 to be released first (with the arp!), and I need to be more familiar and efficient with Spire. I've only had my license since this morning. (the patch was programmed in the demo)
Let's just say this patch is the first one of a full bank (128 patches) I'll release sometime this year or early 2014.

There are tiny crackles. Maybe Spire is clipping internally. I'll do more testing tomorrow when I have the time but I don't think this is normal.
However, don't forget, like I said, that this patch eats 50% of my CPU, probably peaking at 60% when the crackles appear.

Could tiny crackles be the awful re-encoding by SoundCloud? I cannot listen to the sound (on my phone atm).

Uploading in a lossless format and leaving a -2db headroom usually solves the problem with slight distortion on top. As far as I know they still re-encode everything to 128Kbps MP3.

Had a listen to the pad and I disagree. Soundcloud often presents clicks and pops on playback. Many times I listen to tracks and hear the same pops etc. I used to think everybody had the same mixing errors which would be strange. If you click about on the waveform as it plays you get exactly the same pop sounds as sometimes heard as it plays back normally. I listened to this pad a few times. Sometimes random pops, sometimes completely pop free. Try it.
