Great software that emulates a reggae pre-amp. Kill switches, eq, echo and reverb, all work really well. If you add a midi controller then is gets really easy to control. I have run it with audio files and from a turntable using a a/d converter, it works the same with both. Covers all the bases with many parameters editable live. Sarge gets back to you really quickly with answers to anything. Just to add – I have had this since May last year and it has never crashed in that time, running on a windows 10 laptop.
