Seems that ‘reeloy’ thinks differently?
Maybe he put you off!?
Another case of RTFM, clearly states midi is well implemented.
Chapter 8, USING MIDI…may have something to do with it…
• The RC-50 can receive MIDI clock from external MIDI devices
and perform at the same tempo as (be synchronized with) the
external MIDI device. This enables control of the RC-50 using
the same tempo as that of recorders and other equipment.
• Playback of the current phrase and control of All Stop can be
achieved through receipt of MIDI Start and Stop messages.
If Simul-Start (p. 50) is set, you can also start playback of any
desired phrase from an external MIDI device.
