### 5/5 — After using it in BOOGA, you realize..

*2026-07-15*

How extremely useful this effect is.  Just listening to your favorite synths presets thru Octaves will blow your mind.

### 4/5 — Oddly perfect filter

*2026-04-23*

So it’s definitely an extreme filter in my book, and I love it! It’s crazy fun to do overdubs in different filters, and it’s cool to fit into mixes as such a nice but deep way. Haven’t tried the ping drum machine type thing but that sounded ace from the demos. I also feel like this can be used with any instruments to make the mix dope. Hails to old equipment I guess minus the hefty weight ha. Cheers.
