I just started using a Roland R-05 as a replacement for an M10. In terms of sound quality, the results it produces are very close to the M10's--conceivably better in some listeners' estimation. However, in terms of operation I find myself missing several features of the M10 and wondered if, in light of them, someone could point me to a recorder that is more like the M10.
- The R-05 has a red light to signal overload, like the M10, but lacks the green light indicator for normal full levels
- Gain control on the M10 is adjusted through a knob that can be turned even when the device is off, whereas the R05 uses digital controls that won't even engage if one isn't recording and make it time-consuming to raise or lower recording level significantly.
- I really miss the T-marks on the M10. The Roland allows one to splice files on the fly while recording but not to mark them or splice them subsequently.
I don't know if at this late date anyone else is considering this substitution but if so, I hope these observations are helpful.
