Hello. That's a lab power supply. If you intend to do any kind of eletronical prototyping work, you should have one. You won't regret getting it. I am not familiar with the quality of that brand, but the specs look ok.

However, It would be a bit inconvenient to power a synth system from a lab power supply. You need to plug in cables for every time you want to use it, and not confuse the + and - cables, etc. For daily use, I would probably recommend something like the Doepfer A100 kit.

> Some of the parts (555, TL082, LM13700) will operate on up to +/-18V so you may not have to use additional regulators to go from 15V to 12V. Check the datasheets to confirm allowable operation range. However, sometimes there may be other elements in the design that were based on a 12V source like a voltage reference; so check the design. Also providing a local regulator may help reduce noise and other nasty things.
