I use differents synths and hardwares to make music and I use them also in live with my band White Noise.
At this moment, I use Ableton Live for my samples and my backings tracks. I tried to use hardware like Octatrack, but it was so difficult to use it efficiently.
I launch my sounds with a Launchpad Pro by Novation. Sub bass is provided by a Novation Basstation 2 directly controlled by Live with a Roland MX-1.
Some arp sounds are played with a Roland TB-3.
Other synths : a Novation Ultranova and a Korg Minilogue, not set on the photo.
