Hey guys, just wanted to bring your attention to an interesting software app that I found. Vezér http://www.vezerapp.hu/
Vezér enables control of realtime video software, and any MIDI or OSC enabled environments, through the use of timeline based MIDI and OSC automations.
Although it says it is for video software, it could easily be used as a MIDI sequencer as well. My initial impressions are that it is a very useful and flexible timeline. Plenty of MIDI CC and OSC automation curves and it supports MIDI notes. Pretty inexpensive as well. Mac only.
