How long does the battery last on a single charge?

Battery life ranges from 8-12 hours depending on volume level and synthesis intensity. For extended studio sessions, you can power it via USB while playing without interruption.

Can I use this with my DAW for sequencing?

Yes—MIDI IN lets you sequence the FM-1 from your computer or external sequencer, and MIDI OUT lets you control other synthesizers from the FM-1's keyboard. The built-in sequencer also works standalone for creating patterns on the device.

Are the presets customizable?

Completely. You can edit any preset's parameters using the built-in interface, and save your custom creations to the 128-preset memory bank for instant recall during performances or sessions.
