Elektron Octatrack

My favourite hardware sampler/sequencer at the moment. I'm creating whole compositions using it as sequencer and sampling my CS1X and TT303 into Octatrack.
It has 8 track sequencer for internal samples and 8 tracks for midi external gear sequencing.
With parameter locks possibilities are endless . I'm usually using 8th track as master with compressor and equalizer, so 7 tracks is enough to make whole track.
You can add 3 different LFOs on each track and 2 effects + 2 master effects on 8th track.
The philosophy of electron gear is a bit different than other grooveboxes or samplers but once you familiarize with all the functions and shortcuts, your workflow will improve a lot.
