I've tried several mobile apps, and they all have high latency.

Ideally this should be a pluggable and small box that generates piano sounds from the weighted key midi keyboard.

  • What model is your midi keyboard, and does it have a 'real' (DIN) midi out socket, or just USB? Typically these are called 'sound modules', 'synth modules', or 'expanders'. They actually used to be more common in the past than they are now, but there are still current models: hearthemusicplay.com/best-keyboard-and-midi-sound-modules – topo morto Apr 2 '18 at 12:22
  • Both real and USB. – Auralnoob Apr 7 '18 at 14:11

Yes, there are stand-alone MIDI 'Modules' or 'Expanders' A Google search for 'MIDI Expander' 20 years ago would have found several general-purpose or piano-only choices. Now, you'll find mostly 'analogue' synthesis modules or other specialised stuff, but there ARE a few piano modules still available.


The alternative approach is to add a low-latency audio interface to your computer and use software instruments.
