Simplify your setup, my original live sets used more gear then I could actually control properly at once. Scaling back to a DT/DN and an Ipad controlled by the midi from both is fun and more then enough to control. Ipad provides organic tones like rhodes, DT on drum duties, DN on synth duties and most of the music midi sequencing for the Ipad. As a bonus now I can remove the soundcard from the setup as the Ipad can do my usb midi conversion for any additional controllers to the DT/DN. Less things in the chain, less things that can go wrong, less things to setup. I enjoy running the DT/DN into a small analogue mixer as this gives me great tone shaping and instant hands on control to mixing/DJ and adds another dimension to the sound.
For me I spend more time organizing and processing my sample library on the computer (and Digitakt - folder structure, KICKS BASS, BREAKS ETC - breaks labeled with tempo, music bits labeled with key or notes) or my patches on the Digitone then actually writing the material, I find if you have an amazing and unique set of building blocks, one everything sounds better, two it makes it very easy and quick to write new material for new sets. Remember you can move stuff around on the Digitakt HD and the samples will still work and be found in old projects.
It’s boring, it’s work, but when it’s done I can smash out a set in a day and enjoy the creative process much more.
On a note when your preparing your samples in your DAW be sure to Mono them (If loading to Digitakt), I find that mono’ing the sample/stem your working on before you start processing leads to better results and no surprises when you mono it at the end.
It’s better to have a few instruments and know them very well then have a bunch of stuff you don’t know inside out I have found. Some of my best performances have just been a Digitakt and a Novation XL mapped to each channel (digi track) with a fader and each delay/reverb send + the delay/verb parameters. Dubwise.
Organise organise organise, Simplify. Profit.
