HY-SeqCollection2

THIS is the ONE, if you must have only one MIDI FX. It's got pretty much everything and goes way beyond "just" the 5 great sequencers. There's also MIDI Thru (BRAVO!!), a bushel of great modulation types for both self and MIDI CC modulation, and its own internal rack of 9 other MIDI FX, like keyboard transposing, scale filtering, etc. State of The Art, 2019—VERY well done.
