Thanks for the offer, Dslsynth. I haven't worked out the details of the recording yet. I'd like to keep things as simple and direct as possible. I have no need to multi-tracking, and would like to maintain the live performance approach as a standard for recording. In other words, everything I compose I can play and produce all at once, and I intend to keep it this way. Whatever changes need to be made in patches, effects, or mixing are incorporated into the pieces from the beginning.
I'm interested in the Tascam DR-100MkIII. It seems as if it would be a substantial improvement regarding audio quality, presuming I get proficient with it. But again, I'm still exploring. Whatever works best in the end, it will require some careful experimentation.
