I’ve recently upgraded to ableton live studio 9 and that comes with the great and powerful analog synth. Its great for acid lines and I’ve made a patch you can download and use in your projects.
It makes use of Analog, Amp, Reverb and the EQ eight.
You can download the patch from dropbox http://db.tt/xK3n34Q8
You can see and hear it in action with the Max4Live mono sequencer below.
