RMCA Pro offers all available functions, while J.P. and MAAS are limited to certain uses according to their different possibilities. Songs can be recorded in real time, using the computer keyboard, a virtual keyboard, chord pads or an external MIDI controller, and can be reproduced with hundreds of free downloadable different RCS styles. RMCA Pro and Jam partner also support styles for YAMAHA® arranger keyboards. Tens of thousands of those styles are available on internet for free download. - Learn more ...

Moreover RMCA Pro and Jam partner offer a chord progressions random generator. Depending on various options it randomly chooses matching chords from specific chord groups or many common chord progressions and generates via one mouse-click complete songs from any number of measures with variations and fills. This makes the two programs ideal jamming tools and helps to practice GUITAR or BASS in each key with a backing band and countless unique backing tracks, "composed on the fly". Automatic song creation provides incomparable background music for hours!

An external MIDI keyboard isn't needed!

The DEMO versions of the programs have no time limit and generally have all the functions of the registered versions except for the saving capabilities, some special functions and the fact that only the about 35 included demo styles, several hundred downloadable so-called "1-part styles" and (- not with regard to MAAS -) styles for YAMAHA® arranger keyboards can be processed (but always only for a limited time).

All in all the MIDI programs are for you if you would like to turn
your computer into an "Entertainer Keyboard" and to ...

  • make professional music with your computer or a simple MIDI controller actively ? - (Audio & video clips)
  • let a software "compose" tasteful tracks for practicing, video clips or presentations (RMCA Pro, Jam partner) ?

Download Manager for XDigits MIDI software and other recommended programs ... 

Instead of using the download links at the top right it's also very comfortable to use the "XDigits Donwload Manager" to install, update and test the MIDI programs, as well as to delete them without leaving any traces. The manager (a single executable file of only about 340 KB) can be installed into any existing directory of your hard disk or USB stick and started from the desktop or by double-clicking. If desired, the manager can also delete himself from the system at any time.

How to use it: Simply select a software product and determine the installation path, whereby you should use the recommended paths, so that you can also execute the programs in the future without additional effort or remove them completely. That's all.

   My own private playlist: 66 instrumental

( - ???  Usable for Windows system users only  ???)

Important noteUsers of other operating systems need
perhaps an "MP3-player"
 that can handle *.m3u files (playlists),
such as for Apple users for example "Foobar2000" or "VCL media player".
In the corresponding 
players - at the configuration line
provided for it in the settings, 
e.g. under "Play location" at
"Foobar2000" or for execution with a 
suitable Internet browser the
following case-sensitive entry must be made or 
taken over by "copy & paste":


or Click herefor all tracks.

 The "special thing" about all my music files - some of which were created more
than 15 years ago - is that they are "mastered" in an optimal and modern way.
This applies to the uniform sound, regardless of when and how the recordings
were made, as well as to the frequency response, dynamics, volume and sound,
which is now essentially optimized over all years of creation and independent of
the instruments and technical possibilities used, and which corresponds to the
so-called "industry standard" (e.g. for studio recordings of drums, guitars etc.).

  Another special feature is that no permanently installed Internet connection is

required to play the music files. The files have been stored online in a format that
   allows them to be "streamed" "outdoors" as "mobile data" using e.g. LTE
(Long Term Evolution). With the cellular network, mobile data can be
transmitted in greater quantities and at higher speeds over the air interface.
Please activate your network for mobile data playback and start the playlist


in your mp3 player or within your internet browser.
