The Lyra-4 Is incredible as a synthesiser - I am a sound designer and Noise/Industrial musician, and I use the Lyra-4 as a sound generator for my performances and in my production work.
The thing that is incredible about this device is it's responsiveness - The tuning can be so finely patched that you can create beautiful pads, however it can be quite overwhelming for a first time synth user.
I would whole heartedly recommend this incredible instrument, but do take time to practice with it and work out how you would like to use it in your work flow.
