The one and only Max Msp Jitter from Cycling’74, if you want to start making interactive media without writing a line of code then this is for you. Amazing forums, thriving community.
Want to make your audio or midi effects ? Create things that don’t normally exist in a DAW ? Then Max for Live is for you. (Yup, its Max msp Jitter in Ableton Live)
Can’t afford Max ? Then you can always get the open source software Pure data. For basic midi and data manipulation its okay, sadly the community isn’t very helpful and sharing (go figure) and the documentation is very spotty. All in all fine if you don’t need to do anything complicated.
