The LoopDrive 4 plugin by yedey is a free VST loop / beat slicer and sampler especially made for drum loops. LoopDrive 4 cuts a loop into fixed sized steps according to the selected tempo and enables the user to rearrange the sliced beats with its built-in step-sequencer. Then set the loop length with the L and R sliders, and make sure the loop option is selected. Load up all of your instruments ahead of time. Once you start recording the first track, as soon as the first loop is done, use the button you picked to move to the next track and it'll continue to record using your next track.

Unfortunaly, the development stopped and there’s no chance to see a 64 bit version, or to fix bugs that happen in some hosts.

Free download : http://www.audioblast.me/downloadinstalooper.html
It’s a free VST for Windows and Linux, coming in 32 bit & 64 bit version.
It does basically the same as Instajungle : loops a part of the incoming signal, all sync’ed to the host.
don’t hesitate to have a look at the manual ! because it’s not obvious that you have to right-click on the buttons to make them act like “toggle” button and not “push” button.
