Great MIDI control

Amazing app from Kai. So many features for a keyboard app, arpeggiators, chords, scales. Absolute bargain.

Janky keyboard.

The interface is cramped. I wish you could hide everything but the keys and drum pads to make more space. There’s an odd visual glitch where the drop shadow of each key permanently disappears as you play them. Also, I wish you could set it to default to an output so you don’t have to select it for each controller every time. It’s lacking a lot of polish for such an expensive app. I don’t know how this got so highly rated in its current condition.

鍵盤数が最大25鍵まで。足りない。

デザインは、一見良さそうに見えるが、
最大の難点は、一列に表示できる鍵盤数が、25鍵までであること。
iPad で使う今時のDAWアプリの内蔵鍵盤は、37から40鍵程度の表示ができることを考えると、25鍵は、あきらかに少なく足りない。
この手のMIDIキーボードアプリで、鍵盤数を多く確保したい場合は、Xequence AU Keys や LK に、軍配が上がる。

要望
37鍵程度の表示ができるよう希望します。

Not a download and go app

Can’t use this to have my 6 year old practice piano on my iPad while traveling. No audio output.
