HY-MPS free is a block base sequencer.
There are 3 step sequencer blocks which produces midi note events. Playback chain order of seq blocks will be controlled by block chainer. Block chainer is a 16 step sequencer which controls chain order of seq blocks.
You can make midi sequence with combining these seq blocks. Also running direction and step size of each seq block can be set independently. Each seq block represents a quarter note and step size represents divide factor, so if you set step size 4, each step becomes 16th note.
