Excellent Synth Solution
I bought one of these several years ago, and was impressed with the sound quality for the price. However, I didn't use it much since I had other interfaces for recording to my PC.
My synth and keyboard collection grew in the meantime, and I was getting tired of connecting and reconnecting every time I changed synths. Out came the Xenyx 1202. I am able to connect six keyboards to it in stereo (up to twelve in mono).
My better synths and keyboards are connected to the first four inputs which have three band eq. The remaining synths are connected to the stereo inputs. The RCA Tape-In channel allows me to use my iPad apps with a keyboard controller.
Yes, I probably have too many keyboards and synths. I blame it on Propellerheads Reason for sparking my keyboard fetish. Now that Propellerheads charges a fortune for RE's I found I can buy real synths for less. Especially with so many new, low priced synths coming out. I finally had one synth too many though.
I bought a second Xenyx 1202 to handle the excess. Now by splitting up the keyboards I can run the main outs of one into a stereo in of the other and route that into my PA. Each keyboard/synth is at the same volume level. I can run all instruments at once with no hum or noise. I can play any synth and switch to any other when I want, or I can play multiple synths at once. There is plenty of room under the inputs to label everything as well. Also, at first I wasn't sure I would like not having faders for each input, but this works better in this case since it is harder to bump the knobs and mess up the levels.
Sorry for the length of this review, but I could have saved a lot of time if I had this information to begin with, so maybe it can help someone else.
