Ziggy: for recording and making the MP3 files I would suggest using Sound Forge. That's what I used for making the Yamaha 9000 Pro and expansion card MP3's. Make sure you have optimum gain so you're getting a good recorded signal. When you create the MP3 file, set it to save at 128KBits/second - 44.1k 16-bit. I think you may have created your MP3 at a lower bit rate which gave an inferior sound to the other comparison MP3's. Also try to trim any excess silence off the end of the file to make the file smaller. What I heard sounded very promising and I look forward to hear more of the Gensys.
Some people have asked about which programs to use for creating the midi files. I use a variety of programs, including the following:
Power Tracks Pro ($29): perfect starter sequencing program with many features - best "bang for the buck". Available for PC only from
http://www.pgmusic.com/. Master Tracks Pro ($80): Been around a long time and still a very good pro workhorse sequencer. I rely on this a lot for basic MIDI track creation (this is what I used to create the midi files for the piano shoot-out). Easier to use than most - great "humanizer" feature. Available for PC or Mac from
http://www.gvox.com/ Sonar ($ depends on package but around $350): one of the most comprehensive sequencers on the market. Mild learning curve but worth the effort. Records midi+audio. Both Sonar and some other cheaper starter sequencer programs available for PC from
http://www.cakewalk.com/ There are others to choose from like Cubase and Logic but Power Tracks, Master Tracks and Sonar are my favs.
