Features
Read full description

Create your own custom soundboard with support for microphone throughput - be the MC of your own party! It includes various effects like delay, reverb, and distortion, applied to both the microphone and the sample channels. The microphone channel is only enabled when connected to an external audio source, like a Bluetooth speaker. Once connected, you can use the built-in microphone to spit those rhymes. You can mix the output with any audio that's currently playing, so you can drop as many airhorns as you'd like on top of your pre-recorded DJ set. No tracking, third-party libraries, or other nonsense. It does exactly what it says on the tin, and nothing more.
