Pretty useful

As a GarageBand user, I like to use some synth apps for more synths. Just plugins and Audio Unit Extensions in general. I get everything free I can and I’ve found some hidden gems. The only way I found this was because I looked at Fingerlab. I use Mynth and Flynth a lot, and they’re nice. I like the Random button on Mynth. But I wanna talk about the SK-51, after all, I’m reviewing it. I only got it a day ago, but I’m already enjoying the experience. However, the only thing I don’t like about the Fingerlab apps is the paywalls. That’s the only thing keeping the SK-51 from being 5 stats. It’s also nice for GarageBand. In my opinion, it’s better and easier to use than the Sampler. They both have things exclusive to them, but I still stand by what I said. With that being said, SK-51 is a 4-star app. I would recommend.

Midi for desktop stopped working [Intel/Ventura 13.4]

Flynth & Mynth work fine. It's pretty straight forward to connect, idk what the problem could be though. Other than that, from what I remember, this app was a lot of fun for the price. All fingerlab stuff is great price, and really quick to pick up and just get some inspiration. UI is classic and simple, also resizable. There's not too many bells or whistles, but tbh...just messin around it's not necessary. Hope there's an update soon.

Great Purposelessly Crap Sound

First of all I wanted to say that I own all the Fingerlab apps. I love them and the way that they are pretty much all different and useful in a large sea of music making applications, very cool and this is no different but...... Why is it that we cannot use the sampler and pads to be triggered and sequenced by midi? Seems like it would be an easy enough thing to implement? Maybe I’m wrong but if we could use those sampled sound sets, user created, it’d be freaking so great. That would make this thing so much more useable in my opinion. Maybe it’s because you guys are trying to make this SK as similar to the original piece of hardware? I don’t know but I would easily add one more star and would be thinking if I could, add a hundred more stars to the review. One way or another this little guy is fun and adds a very cool low bittish, purposely crappy dimension to some of my tracks. Love it but please kind devs make those pads midi accessible!
