CHANGED: ‘Wotja Store’ title is now ‘In-App Store’ and we display the active mode after that, e.g. “FS: ‘Pro’“.

Wondering whether to start paying

What I want is a music generator that will produce an ambient track at the click of a button. I don't want to explore it, or record it, or edit it, or produce it, or adjust it, or anything else. I just want it to work. The free version of Wotja does just that, for half an hour, and then you have to click the button again. At least, it does 9 times out of 10. The tenth time, it starts running but no sound comes out. All you can do is quit and reload. Worse, sometimes it hangs and you have to force it to quit. I wonder if the paid version would give me these problems too. I wouldn't mind paying if I knew it wouldn't.

Developer Response ,

Hi and thanks for the nice review. We are very happy to hear you enjoy what Wotja creates with just one button press (which I presume means you are using it in Flow mode)! If it sometimes generates silence that could be because of the way the Randomization Preset (RP) is generating the auto-mix (some of the templates can take a bit to start playing). 'Pro' mode lets you edit/save RP and a 1 month Pro Subscription would let you edit those. Wotja certainly should not at any time require a quit or force quit, only a tap of the play button to restart play! Could you please get in touch via our web contact form and tell us what version of macOS you are running, what audio output device you are using etc.? We will do our best to get to the bottom of it for you! Best wishes, Tim and Pete.

Picture the scene: it's Sunday morning chez Less de la Clue, Monsieur Huh-What is 'tinkering' again, bless him. There is an iPad looking nervously at him, trying to look busy and all the gear in the world hoping they look busier.

Wotja hasn't experienced the delights of the Huh-What 'workflow' and therefore fully believes that it can bring to life the brain cell waiting for it. The fool.

But wait! What is this? You might even ask, Huh-What is this? There seems to be... melodic sounds emanating from the monitors! A cautious smile creeps across the face of our protagonist. Can it be? Could this be real? Is he, finally, after a millenia of midi-based turmoil, could he actually be MAKING MUSIC!

Yes folks, this app needs just a single brain cell to work. I know because even I have wrangled a toot, a peep and a toodle out of it.

Thanks to our developers, I have now changed my name to Huh-Wotja.

Why make it crippled?

Long ago and far away, I had Sseyo Koan Pro and Koan X. Loved playing with those. Occasionally, I take a look at this product in the hope of getting back to the future. Sadly, while there appears to be much potential, the interface is still inelegant and confusing. As for this version stupidly having 2 minute time outs, it makes evaluation difficult if not impossible. I would not mind at all buying a cut down version, and that might well encourage me to buy a one time payment full version, if only I could get something going before the app cuts me off.

UPDATED: Hi Nic, Glad to hear you loved the paid-for SSEYO Koan Pro/Koan X apps and thanks for taking the time to leave a review. Wotja is a complex tool and the multi-level UI is the best we can do right now; it represents a huge amount of work but we will of course keep improving it! As of V21.7.0 the timeout in Free Mode is now 30 minutes :). Hope that helps and best wishes, Tim.
