These JS midi fx use the new sysex implementation and are usable from REAPER version 3.05 and later.

The Roland JX-8P editor controls all the parameters on the JX-8P.It could be modified for use with the mks-70.At the current time all 49 parameters are not visible on most computer screens
but can be accessed using envelopes or front page knobs etc.

The first 32 patch names are what I have in my JX-8P currently and can be easily changed.

The Motif ES fx should be fairly obvious to use.They are for use in mode song or pattern.You can use 1 channel mix on each track (choose the channel) and 1 instance of the master mix (channel independant) to access other parameters.These fx are less complete than the Yamaha plugins but have the advantage of integrating well with REAPER for parameter recall.Most musically useful parameters are covered.

The 01X JS plugins also do not replace the Yamaha ones but are useful when using the 01X to mix tracks sent to the 01X,sending them back to REAPER via the 01X recording bus.Users of the 01X will most probably understand quickly the utility.

They represent also a "proof of concept" for me to learn how to program midi sysex plugins with JS.

Feel free to use and modify.Some maybe updated as I learn more about JS programming.
