Better sound quality, hold option, MIDI aftertouch support (mapped to Expression).
I do like the synthesizer but one thing that was a minus was that it was pretty easy to introduce artifacts into the sound if you weren't careful. So it seems they have worked on the sound quality and it is cool that they got the suggestion (D.N.P/Brumcast) to introduce a hold function and they put it in pretty fast after the suggestion. Would be great if you supported the developer as the synthesizer is unique in Android land. It is a synthesizer that comes with a lot of features already but the developer is open for more suggestions and seems eager to expand it as much as possible. My biggest wish is that the arpeggiator/16 step sequencer had a bpm counter with the slider as it is hard if you do sequences that you want to synch up with other project or if you want to use just EasySynth for a project and need to synch up the different parts.
