Strange behavior, no tech support – Kauldron Synthesizer Review

I adjusted the filter, including the adsr to something approximating a brass sound, with Osc 2 and 3 off. Then I applied some glide and suddenly the sounds became low volume beeps and there was no way to recover, no reset to default seems to exist, couldn’t find it in the manual either. Exit the app,leave it alone for 24 hr, and it seems fine, glide works the way it should. After reading the manual, which is more of a list than explanation, I got more ambitious and added the other Oscs, fooled around with the second set of adsr and drift and voices, things seemed to work, although the second adsr set is a bit weird. I had written to Yonac about Kauldron a week before, got no form reply nor tech support. I think I could rate this app four if I thought there was any support. I haven’t tried presets yet but I think I will have to, because the app certainly doesn’t load with your last settings, in fact some knobs are not where you would think they would be and others have stayed where they were. Default behavior and reset are not in the manual, nor is there a a good discussion of all adsr behavior. The filter settings don’t have any meaningful indices that I can see, you don’t know where the resonance is, and there is only one (steep) roll off so you really can’t do brass effectively. EDIT: I have again used the Yonac website contact form and received no acknowledgement or response, so I have to conclude that there is NO tech support, so I have reduced my rating to one star, because you can’t do no stars. Second EDIT: I actually got a response after two days, to my 3rd email, but the tech seems not to have read the manual. I have replied but don’t have much hope for a real answer. Third Edit: I have written to Yonac at least four times, and received one reply mentioned above, so I really can’t understand all the rave reviews, the ADSR is goofy and uncalibratable, for instance if you set what you would think is a very short attack and set what Yonac says is a high amplitude, it takes seconds for a tone to reach peak. This is ridiculous. Fourth edit: There is no version history, there is no tech support, I have to believe this app has been abandoned. You can not get into the Yonac forum on iOS, but I have posted from my Mac and there have been a few views but no response, so I have to think that it didn’t sell, and that some of the problems I have described have been experienced by other who also got no response and deleted the app. I am not ready to give up on it, but I am absolutely you can not synth brass adequately, because the adsr is crazy, the cutoff is way too steep, and you can’t place the resonance with any certainty. There does not seem to be a brass instrument in any of the many presets , which would seem to make my point. I notice there are only a few developer responses in the reviews and they are all canned.
