Phase Seq easily generates unquantised looping MIDI sequences that are more difficult to achieve in some hosts. Up to eight events are triggered at manually set phase positions and three columns of sliders are dedicated to modulating the position of each trigger by the LFOs.
The immediate application would be for loose timing variation, or special effect sequences, like speeding up or slowing down, or for sequences with erratic timing. Some more subtle timing effects are possible, e.g. by scaling the effect of an LFO on each step (as pictured on the screenshot) the LFO will stretch and condense the beginning of the sequence elastically. LFOs may be synced to different host rates to create complex repeating patterns.
Phase Seq is designed to run lightly on CPU to accommodate the use of multiple instances.
