The Yamaha REV500 uses CC/Program Change using values 0-127 for all parameters. Most parameters range from anything but 0-127 so interpolation of values is required. Program change using CC is not possible for values above 128 so PRESET patches from 29-100 cannot be selected remotely. However the panel can load preset data into temp buffer.
