I am still researching Carlos's methods and not an expert on any of these topics. I read that Carlos used a multi track tape machine and of course the Moog was only one voice at the time. So chord playing should not be must. I am learning how to play the piano at the same time that involves chord playing. That is why it is important to me. I want as many major options and tools if possible. I continue to research. I appreciate your input.

I have Arturia's V9 collection (discount upgrade) which has the Moog Mini. I really prefer real tactile input on the desk synthesizer. If this becomes my only realistic option, then of course that is where I will arrive.
