Boom Chak - Classic Analogue Style Drum Synth for Kontakt​

Each drum sound has dedicated controls like volume, type, pan, pitch, decay, modulation or additional amount of noise, plus six effect switches. This makes the Boom Chak an extremely flexible electronic percussion tool and a really cool instrument to play with.

The effects (Convolution Reverb, Replika Delay, Chorus, Lo-Fi, Flanger, Overdrive) can be added to any individual drum sound or to all sounds at once. The effects are quickly accessible and all effects are editable.

The Master Control contains two filters (Low Pass Filter with an Envelope Follower and LFO, and a Hi Pass Filter), global Pitch Control (-12 to +12 halftones) and Velocity Sensitivity control.

The Auto Rhythm Editor is a simple but effective pattern creation tool with a total of 12 patterns (each pattern has 2 x 16 steps). The Auto Rhythm patterns can be triggered by a key or with a click. The tempo will be synced automatically to the master of the DAW.

The V2 update contains a new NKI, the BC-2000, a more digital sounding version of the BC-2.
