Riccardo Loi (born December 5th, 1999), mainly known by his alias, KaleidonKep99 (or Keppy), is an Italian member of the Black MIDI Team who occasionally creates MIDIs, develops SoundFonts, and maintains comprehensive programs. He has been in the Black MIDI Team for well over a year and has been a very influential member in the community.

Although he is not an explicitly exclusive MIDI maker, he has blackened some MIDIs in his very early days, some of which are Bad Apple!! and Plain Asia, both part of the Touhou Project soundtrack. He is one of the iconic SoundFont makers of the team proficient in programs such as Viena and Polyphone; some of the SoundFonts he created in his early days are Riky's Ultra-HD Piano (known today as Keppy's Steinway Piano), Farfisa (many versions), Bosendorfer, and Steinway ERxx/EVx9.

His first channel, Riccardo Loi, was removed after copyright infringement, while the second one, Keppy Studios, was deleted by himself in early 2015. He occasionally uploads on his current channel. 

Personal Life

Loi has played the piano since he was 4 years old for nearly for ten years. He devoted himself to music from middle school until high school, after which he devoted himself to information technology (IT).

He regained interest in piano during 2012 when he saw some of Gingeas' videos about black MIDIs, and began producing his own videos on his computer.


KaleidonKep99 is well-liked by many people in the team as opposed to a few years ago where he had some internal conflicts with a few members.

Keppy's Steinway Piano

This is his main project.
Around the end of 2014, KaleidonKep99 developed a soundfont called Riky's Ultra-HD Piano. After he got banned from the BMT in November 27th, 2014 (which was not lifted until September 7th 2015), he began to dedicate his time to the SoundFont, lately renaming it to "Keppy's Steinway Piano".

This SoundFont is one of the best projects he ever made, followed by the Farfisa Grand Piano. It was the first of his SoundFonts that used the open-source SFZ format, instead of the outdated SF2 (closed-source, owned by E-mu Systems) format.

It can be downloaded here: Keppy's Steinway Piano

Farfisa Grand Piano Series

This soundfont is not supported anymore, since the release of the Keppy's Steinway Piano.
In the 2013, KaleidonKep99 started a soundfont series (that was also ported to FL Keys) called "Farfisa Grand Piano," now dedicated to classical music and not to Black MIDIs.


The logo used for the series since the release of the 4.1 version.

"The first version is, really, the last version able to play Black MIDIs, but sadly isn't able to play The Anti-Chlorobenzene 8.1 or Bad Apple 5.1 without skipping notes.

The second version was a failed version of the first one, bass boosted, the third version too. Now the Farfisa Series is on the 5th generation, with the 5.0 available on my website. These two versions are intended to play classical music or to be used for remixes on FL Studio." - Kep (Actually, the 5.0 was a fail too, now SynthFont distributes the 4.01)

Now the project is being developed by SynthFont Ltd.
