IonFire.Manual was written to help create semi-automatic shows for the Merlin Electronics Ltd hardware. Each sequence can contain any number of cues so you could fire an individual firework or a whole sequence.
From within the software you can upload your sequences to the hardware, perform a channel check, and trigger the show if needed. Alternatively the Merlin interface can be programmed to step and fire sequences in order for you to trigger the sequences with a press of a button (no laptop required). Alternatively the fireline on the modules themselves could be pulsed to trigger the sequences if this method is prefered.
IonFire.Manual allows you the flexability of a manual firing system to respond to varying firework times whilst also enabling you to create complicated sequences.
