I’m impressed by the quality of the sounds and the mix, I didn’t think Hydrogen could sound so good, what drumkit are you using? Also the synths sound very good!
I made the drumkit myself using tons of layered sampled gathered all accross the web… To make the whole thing easier, I created a script that reads the sample settings from a config file and recreate the Hydrogen Drumkit XML. Basically, I just have to change one sample name it my config file, and it goes and looks for the different layers, order them and create the Drumkit XML File… Handy to test different samples in a fast way…
Another trick that I get from being an actual drummer is to have a lot of variations of the sample pattern, that makes the song sounds more human-like as a real drummer almost never plays twice the same pattern (changing cymbals, adding a little break and so on)…
Finally used the Multi output track option of Hydrogen to record each instrument on a unique track in Ardour and spent a lot of hours to set up reverb, compressor, eq and so on…
