Fabla's interface

Fabla is an open-source LV2 drum sampler plugin instrument from OpenAV. It is ideal for loading up your favorite sampled sounds and bashing away on a MIDI controller. Or if it’s crafty beat programming your after that’s cool too! The ADSR envelope allows the shaping of hi-hats and kicks while the compressor beefs up the sound for those thumping kicks!


good idea, but without cut groups it pretty useless. I find myself still going to hydrogen for drumming and sample sequencing.
