Skaka is a sample-based sequencer plugin for shaker percussion instruments. It has 12 slots, each with its own instrument, parameters (lots of them!) and pattern. We've built both the sequencer and the sampler from the ground, to optimize this instrument for these types of sounds. Each pattern contains events, with individual parameters like pitch, velocity (as in how fast the instrument is shaken), and envelope.

This is a great little plugin that after I watched the video bought in an instant. If it could save me to record tambourine just ONCE it will be money well spent!
