@Diegodj > Thanks for your comments and suggestions. I've provided answers and comments to each of the items below.
1) Sorry, unfortunately this isn't possible for the R1.
2) This is not something that can be adjusted by software, it has to do primarily with the hardware.
3) I don't understand what you mean by "live hotcues" ?
4) With an MP3, the maximum "wide" is 70%, this is due to compression and artifacting of the audio when stretched beyond that amount.
5) Unfortunately the processing limitations of the hardware won't allow this.
