Thank you Scottyee. Some people like simple things, I like it complicated. Actually it all started because I wanted an organ and found out they weren' t imported to my country. The option was an arranger (still called portable organ here) an I acquired an used Psr 1500. It got me amazed and when I decided to upgrade (BECAUSE OF YOUR FAULT FOLKS) there was no tyros or psr 3000 available so I bought a Korg Tr which was a complete different machine and I wanted to mix its sounds with the psr1500. Using a Roland pedalboard I made my first "homemade organ". Later I bought the Pa500 and also did the same thing to integrate it to the set up. The original idea was a two manual organ but I found it easier to "fill" the gap betwen keyboards using an extra loose keyboard (the MS keys in this case) So I created the spaceship you know. I suppose I'll be upgrading the arrangers along the time.
