User reviews

My arp

I bought this when I was on the hunt for floaty pads and didn’t really find what I was looking for… but I fiddled about and made my favourite arp ever! I use it far too much. Then I made a nice clean sub-bass on anout 2 minutes. Intuitive app with great potential.

Still no KT

It still doesn’t have an essential feature like Filter Keytrack.
Several people have complained about this, disappointing that in all these years it was not addressed.

Smooth layout

I really like this very stable, well designed soft synth. I'm taking off one star because I feel like both main oscillator should have an independent amp envelope, for pads or whatever.. The low pass/High pass/ Band Pass filter etc section is very flexible, the best I've ever used in fact. I wish every synth had this type of manipulation. I've already created some very lush deep analog type pads. I don't really like the stock effects except the reverb and delay which are usable, and that's the main thing. I absolutely love omega too, I've made amazing rich sounds on it. I also own bleass reverb, filter and delay so I'm familiar with their workflow. Without sounding greedy, I believe that people who own the iPad versions should have a small discount on the Mac os versions and vice versa. I hope to see an update with the independent Amp Env especially...Thank you bleass

Thank you for your nice, frank feedback, it's been heard.

Un classique à avoir

Très bon synth soustractif. Pas le plus complet mais l’un des plus agréable à utiliser et un des plus léger tout en permettant de faire pas mal de sons très différents

Response from developer

Merci Julien, c'est effectivement la polyvalence qui fait son tout, entre (beaucoup) d'autres.

Yep! STILL GREAT!

Started out great. Recent update made it even better. I like the interface and the sounds I get out of it. Well done!

Response from developer

Thank you for your support anickt! We are already working on v 1.2 bringing even more new features and presets!
