... use styles for YAMAHA arranger keyboards with RMCA Pro:

RMCA Pro since 04/2016 imports and processes styles for YAMAHA arranger keyboards. Thousands of those styles with the extensions *.sty, *.psr, *.bcc and more are available on internet for free download. However, since these styles are made for many different keyboards with many different specifications, voices and so on, it is recommended to convert them with Michael P. Bedesem's fantastic MIDIPlayer into General MIDI format.

  • Simply select in the player's setup section GM Sound Card (or XG Sound Card) as instrument and GM (or XG) as voice, if you want to use YAMAHA styles with your PC.
  • Add (lots of) style files and let them be converted automatically in batch mode in no time. 
  • Within RMCA Pro, once you have loaded a style, you can combine its main parts, fills, intros and endings as you wish.
  • If you want to get out the whole potential of your work within RMCA Pro you must save your variations-sets as rcs-styles. Please note: Created styles can either be saved as *.rcs files (RMCA Pro's own style format) or as *.mid files (MIDI files), NOT as e.g. *.psr or *.sty files (YAMAHA's style formats).

... decrease dramatically latency problem by replacing the MS GS Wavetable Synth:

  • Download "VirtualMidiSynth" from http://coolsoft.altervista.org/en/virtualmidisynth (or look up the name in a search engine)
  • Download one of the free sound fonts, suggested on that same page
  • Install "VirtualMidisynth" and configure it as follows: 
       - make it the default MIDI device
       - add the soundfont you just downloaded to it
  • In the advanced options tab reduce the additional output buffer. Try to reduce it near to zero!
  • Run RMCA Pro or MAAS, select "VirtualMidiSynth" as MIDI-output and enjoy playing nearly lag-free!

... connect RMCA Pro or MAAS with a DAW:

  • Install LoopMIDI, a virtual loopback MIDI cable for Windows XP up to Windows 8, 32 and 64 bit, from http://www.tobias-erichsen.de/software/loopmidi.html (or look up the name in a search engine)
  • Configure 2 virtual MIDI-ports (e.g. loopMidiPort 1 and LoopMidiPort 2)
  • Run RMCA Pro or MAAS and select "loopMidiPort 2" as MIDI-output
  • Connect your MIDI-keyboard or your MIDI-controller with RMCA Pro or MAAS via MIDI-input
