This is just a simplest mixer one could get for the studio work – Samson PL-1204 (mixers for a live performance are another category). My set-up has several sources of sound that are described in more details below:

• A-90EX keyboard
• Roland XV-3080 synth
• Waldorf Q synth
• Poly Evolver
• Computer’s sound card

They all have to be plugged somewhere for me to be able to hear them and this is what the mixer does: it combines all the sounds all the other boxes make. I also use it to produce recording of all hardware synths (software’s output is already on the computer).
