Dennis,
I will be glad to clarify the situation. The G1000 has "one-touch memory", which is unusable. This is a single button which only works for the built-in styles. Pressing it has an effect of setting a fixed right hand lead voice. I am not sure what other parameters it sets or clears, but with its sound selections not being programmable I had never used it (I tried 8 years ago, when I first got my G1000, but quickly gave up).
The G70 has 4 buttons which recall user-programmable sounds for all the solo parts, right and left. This works for all the preset and custom styles, so to me this is a great improvement in being able to quickly select sounds for a currently playing style.
Roland documents which parameters are supposed to be memorized and recalled by this OTS function. Unfortunately, while recalling these parameters, it also forces the arranger chord recognition to Intelligent (that's Single finger in plain language) setting. That is where my problem is.
I contend that in proper operation this function should allow you to memorize the user-desired setting for the Arranger chord recognition, or better yet, it should stick to memorizing the documented parameters, but when invoked, only recall those parameters, and no others. In either case, the OTS memory should only recall what it has memorized, no more and no less.
I don't know if you use the OTS on your Tyros, but higher-end Yamaha keyboards have had this for years. I was certainly looking forward to using this facility on the G70, but with the keyboard unexplicably changing the chord recognition type each time I press an OTS button, I can not use it.
I don't care whether it is called a bug, a design flaw, "product anomaly" or any other name, but this operation in its present form makes no sense whatsoever. I hope that Roland addresses it soon.
Regards,
Alex
