What’s “Keppy’s Software”?

This is the name I use for publishing my software, targeted towards professionals.



OmniMIDI (Formerly known as Keppy’s Synthesizer) is a MIDI driver for professional use.
It is a fork of the original BASSMIDI Driver by Kode54.

Its main features are:

Source code: OmniMIDI source
Releases: OmniMIDI releases

Keppy’s MIDI Converter

Keppy’s MIDI Converter (Formerly known as Keppy’s Spartan MIDI Converter) is a freeware, fully functional MIDI to WAV converter.

Its main features are:

Source code: KMC source
Releases: KMC releases


An extension of OmniMIDI’s engine.
It allows developers to directly interface their application with the driver, to get rid of the latency and unresponsiveness introduced by Windows Multimedia.
