### 5/5 — Great synth, Sonically Brilliant

*2026-04-29*

The VAPoly16 is a great sounding synth but I have found the Pitch Bend range parameters are not exposed and is permanently locked at 1 octave up and down, but using the KeyStage Keyboard Controller app to bend just 2 semitones when using a MIDI keyboard is brilliant.  This is a first rate Synth App

### 5/5 — Amazing
