Customer Reviews

First impression

There obviously is a lot to this beast and considering how many modules, eFX , etc, there are and the user interface is pretty good too. Sound quality on my iPad Pro is good. No artifacts when switching presets. It has a lot of categorized presets, and some really good ones at that. Lovin' 'Trance Chords' right now. Functional access to the keyboard while playing back a recording is great allowing playing along with yourself or some other imported recording. A very nice touch. It would be nicer if you could record the live playing back onto the recording that's playing, merging the two or adding a second track or something, at least I've not found a way.. Kaspar offers a boatload of features. The setting for changing between the traditional keyboard and the ribbon keys should not be buried in settings. It should be a toggle on the keyboard. Adding a ribbon strip controller would add even more sound versatility and playing style capabilities. They buried the note hold button on the Edit screen.

Wow, Another Winner From Yonac!!!

I purchased this app even though I'm still on an iPad 4, as there will be a newer model in my future, just as soon as iOS 11 is officially released. To maximize performance on an iPad 4, go into Preferences and change the audio generation setting to Good, then change the Buffer Size to 512. I left the Polyphony at 8 but it can be lowered even further if needed. Of course, running a memory optimization app never hurts, as well as all the normal procedures for ensuring best audio performance in iOS.

Personally, I really like the presets...great variety, and lots of character, especially ripe with so many morphing and layering possibilities. This synth is going to be truly useful and fun to play with, I can feel it in my bones! Just have to learn and feel comfortable with the interface, as is usually the case with something a bit more complex. Once again, Yonac does not disappoint!

Where is Bluetooth for Bose Soundlink Headphones?

Your sounds are beyond awesome. It took some time to figure out how to save my personal presets to a "User Bank". Once I figured it out, it work's well. My only complaint is Bluetooth immediately found all my other iOS keyboards,but not through Bluetooth on this synth app? If anyone know's something I am missing, I would love to know how? Been in Electronic Music for 40 years and own all of the Keyboard, Arturia, KVR, Moog, korg and about another fifty or more 5 star Synths. All of them automatically pickup my Bluetooth headphones, without even going into settings? Give me Bluetooth Audio through my Bose and I'll make it 5 stars! Again getting Bluetooth automatically on my keyboards, just no audio unless I plug a pair of phones into it, and I really gave up on cord headphones awhile back. Thank you!
