Yup, he's done quite a lot of patches for my products. Wow, what a small world!
Seanm, the R-09 doesn't have XLR inputs, which makes things a little more complicated. I wanted something that would work out-of-the-box with my setup with a minimal amount of equipment to lug around. Also it only goes up to 48 khz quality (zoom can go up to 96 khz). I've also heard that the screen scratches up really easy, as well as having problems with MP3 playback and variable bitrate playback. Not to mention that its noise levels aren't great, which is a bit turn-off for me since I work in the sample industry and thus am crazy about noise levels.
Of course, I'm basing my opinion on a lot of rumors in addition to the technical specs of the recorder, but I didn't want to risk it and hope that I don't encounter the same problems with it as other people.
And the M-Audio MicroTrack... well let's not go there, I've heard way too many terrible horror stories about firmware problems, etc.
I'm sure the Zoom H4 has its own set of problems, but so far I'm really getting my money's worth. I've recorded a lot of sound effects with it as well as used it as a mobile jamming tool (its multitracking ability is GREAT for that), as well as a tool to record tracks for tunes (I'll put a song from my computer onto it, as simple as copying files to an external harddrive, then take it somewhere and record some takes over that). Three of my friends are buying their own after I showed it to them.
Oh, and you don't have to install any software in order to connect it to your computer and copy files off of it, since it acts as a removable storage unit. That's a big plus, IMO.
