I like the concept of it, and I loved much of the results. And I like the name
and the form factor. I feel like it is an instrument aimed at my heart (and wallet), but I have a lot of conflicting thoughts.
For guidance through the conflict, I am going to rely on my 2021 pledge not to buy any desktop synths or FX. With that, I can step back and see that I can (and do) get a similar range of sounds from my existing gear and I don’t really lack for inspiration there either. Time will tell though, if I find myself trying to make room for a Strega in 2022 or so 
Re: PT2399: it’s possible there is more going on than just the raw chip and the character’s a bit different than we’ve seen in other instruments. (It’s also possible that’s not even the chip, though it seems like the most likely candidate when he said “karaoke delay.”) To me, it seems like a lot of noise and sometimes that’s very welcome, but I can easily see myself wishing I could cut it back by 2/3 while keeping the same overall character? And maybe that’s doable (especially with the filter that was mentioned) but we didn’t see it much in the demo, or notice.
(Come to think of it, in the Instagram livestream there were some lovely drone textures that weren’t very noisy at all; it could just be the oscillators were being modulated just so but maybe the delay can be calmed somewhat as well.)
Re: Lyra-8: it’s a lovely instrument and I found it inspiring, but also it has a very dominant personality. You either have to work to file the edges off and make it fit with other instruments, or just let it have its way. It is definitely an instrument, but not quite a synthesizer really. I made an album that featured it, but I also grew a bit weary of it and traded it for a Polyend+Dreadbox Medusa and don’t regret the decision. I will credit the Lyra-8 for making me fall in love with touchplate controls though, and that love continues in different form with the 0-Ctrl and Microfreak.
