RMO
Player & converter for workstation synth banks (Motif · Montage · MODX) to SoundFont
RMO reads Yamaha workstation files (Motif XF, MOXF, Montage, MODX and Montage M / MODX M — the YSFC format), extracts the Waveforms (multisample banks) and converts each one into an internal SoundFont so you can play, organize and edit it. It handles huge packs by streaming, exports .sf2 and runs as an AUv3 plug-in. All on-device; your original files stay untouched.

FAQ
What is the YSFC format?
It is the file format of Yamaha workstations (Motif, Montage, MODX and Montage M / MODX M), with extensions like .X7U, .X8U and .Y2U. RMO reads the Waveforms (multisample banks) from those files.
Which keyboards is it compatible with?
Workstations that save in the YSFC format: Motif XF, MOXF, Montage, MODX and the Montage M / MODX M lines.
Does RMO convert to SoundFont?
Yes. Each Waveform becomes an internal SoundFont (.sf2) that you play in the app and can export to other samplers.
Can it open very large files?
Yes — it reads by streaming, so hundreds-of-MB packs open without blowing up memory.
Is RMO affiliated with Yamaha?
No. RMO is an independent product. Motif, Montage and MODX are trademarks of Yamaha, used only to describe compatibility.
When does it launch?
Coming soon to the stores. Follow @rsjb_app for the launch announcement.
