What's new in 1.41
• Export your bass line or a whole Song as audio (WAV), alone or together with the MIDI file, in a folder named after it
• Picking a bass line or a progression while playing now waits for the next bar (adjustable in Settings)
• Live MIDI In: choose what the bass does when you lift your hand, keep playing, stop at once, or stop at the end of the beat. Fill to End now works with it and ends on the last chord
• New MIDI controls: Start, Stop, Fill Start, Fill Stop, FILL TO END LENGTH and, in the plug-in, PLAY LOCK ON / OFF
• MIDI Map renamed and grouped like in the other Lumbeat apps, keeping your assignments. Controls respond only on their own channel, and CC buttons act on press only
• Line Editor: BACK TO ORIGINAL always restores the line you started from, and MODERATE and MID lengths give the same result every time (use the dice for random ones)
• Song mode: PADS 1-8 and RANDOM are ignored while a Song plays
• Plug-in in a DAW: follows the cycle (loop), stays in time when you move the playhead, rewind or bounce from any bar, and a Song started from the host plays to the end
• Plug-in, Song mode: new SONG MODE: PLAY FROM setting, from the start of the Song or from the DAW's position
• Settings are now kept between launches
• Bug fixes
