SEQ3X64 is a MIDI step sequencer, with two melodic tracks and one drums track. Each track can be from 2 to 64 steps long. Up to 16 projects can be stored in the sequencer memory, each project containing up 16 sequences on each track.
Each step on the melodic tracks has its own configuration (note number, velocity and gate length), and can be tied to next step in order to get any note length. The two melodic tracks can also be transposed in real time.
The drums track can trigger 16 different events (note number, velocity and gate length). Each step on drums track can trigger the 16 events at the same time.
The three tracks can be configured independently in terms of direction (forward, reverse, alternate) and time division (1/4, 1/8, 1/16 and 1/32). Each track can also be used in triplet mode and can have a different number of steps. Tempo can be set from 30 to 300 bpm. SEQ3X64 can be clocked internally or externally, and it can provide MIDI synchronization data to other MIDI devices as a Master.
SEQ3X64 has been specifically designed to stay compatible with older iOS versions (iOS 5.1 minimum). A nice way to recycle an older iPad...

IMPORTANT : SEQ3X64 requires a iOS compatible MIDI interface connected to the iPad via a Camera Connection Kit (for iPads 1/2/3) or a Lightning USB cable (for iPads 4or greater, iPad Air, iPad Mini and iPad Pro)
