Great app! But a few problems with Audiobus...

I love the preset synths and basic UI with its own customizability. But when trying to use it on audiobus to connect to any midi device or FL Studio it blanked pretty hard only giving me one tone of sound and consistently hitting that key until I reset the app. I would really hope that this gets fixed soon because I want to use this in my music!

Best app for chiptune

Good chiptune-oriented synthesizer with a nice interface. It's simple enough to use, with enough depth to be creative.

Note to developer: the pitch sweep fader still doesn't connect to the pitch sweep function. However, you can map one of the sliders in the "User" panel to Pitch Sweep. That slider doesn't also animate the Pitch Sweep slider.

Awesome plugin!

It’s not just chip sounds, but you can play around with the filter and modulation tables as well. Custom waveform support would be nice. Unfortunately, glide does not work, and certain sounds can cause crashes.
