UJAM Beatmaker requires MIDI note input for playing and recording musical performances, and optionally pitch bend, modulation and sustain pedal data for added real-time variation.
If you have a MIDI controller (keyboard), this will be the easiest and most straightforward MIDI input method, and it’s the most fun as this way you control your virtual drum machine in real-time.
Of course, you can also control UJAM Beatmaker by using MIDI step sequencers or by entering MIDI notes manually into MIDI tracks.
For getting to know UJAM Beatmaker, for testing purposes, and for trying out various arrangements, you can also use the interactive keyboard in the middle of the UJAM Beatmaker window. This works best with the Latch function enabled.
Mind you, that notes played on the Interactive Keyboard don’t get recorded into your DAW.
