In your situation, it sounds like the PMA-5 is doing an excellent job at acomplishing what you need it to do. And yes, at the time the PMA-5 more than met the need for musicians to have a tool that sounded good and was cool to use. My point is this, the whole point in have a portable unit is portability. This is why it is very important for me to have access to more than one key when I'm out and about. In fact, I find the QY-70 still quite limiting at times with only two octaves. This is why I bought a second one. I hang out at coffee shops composing whole complete pieces using both QY-70's. Then I use my laptop to save all the data. This works quite well for me. If I ever need to do more I can use my studio to go even further. To be honest , the QY-70 HAS MADE MY STUDIO SEEM VERY OUT OF DATE. To sum it up in a phase. I feel that this is very simular to the monophonic and polyphonic synths. Back in the day, monophonic synths did what they were created to do. And they did it very well. Then came the Polyphonic syths more cooler and you could get what you wanted quicker. The monophonic synth didn't change in sound, they sounded as cool as they ever did. In some cases cooler. But progress always pushes envelope. In a year or even a month the QY-70 will seem very out dated. So to answer the original question I feel personally that the QY-70 would be an excellent subsitute for the PMA-5 that is, until next month/year when someththing that fits into a watch will record unlimited midi and audio tracks.
