BEB has released SEQ3X64, a MIDI step sequencer application for iPad. It provides two melodic tracks and one drum track, with each track 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), time division (1/4, 1/8, 1/16 and 1/32), triplet mode, number of steps, etc. 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).
Price: $4.99 in the App Store.
