Congratulations! I bought one in early February and am still digesting all of what there is to know about it -- and SQ01. I don't have any other software for sequencing, and the learning curve for SQ01 is also daunting. For some help, I had downloaded S-90 manuals from the sninety.com site and there's a helpful one that does not come with the 'board, and it's a Power User guide for Master Mode. Very helpful in getting one familiar with how this thing is set up. I am a software trainer and have been also trying to figure out some courseware for teaching folks how to use this beast, but for now, I am still in the learning mode. My jam-mates are digging the keyboard, and as a performance keyboard, it's amazing. I just need to get the programming part together to be able to save my sequences to the smart card! Not particularly intuitive, this, but it's coming together.
