Overview

SF2S1 is a tool to convert SoundFont files (version 2 and above) to S1-format, the file format of the Yamaha EX5/7 synthesizer.

There are many electronic instruments and samples in the public SoundFont format, that can be downloaded from the internet.
Getting the samples out of the SoundFont file, loading these samples by hand into the EX5/7, setting all the parameters and building it to waves and voices again is a tedious job, and can be done in a more easy way.

This version of the program is a preliminairy release that is restricted to converting one SoundFont instrument and its samples to an EX5/7 wave and samples.
Parameters that are converted in this version are

Use SF2S1 in 3 easy steps:

  1. Open a soundfont file (extension: SF2)
  2. Select an instrument in the TreeView
  3. Choose 'Copy Instrument' from the Element menu

The program writes a S1M file that you can feed into your EX5/7 (Disk - Load - Wave)
To play the wave initiate a Voice, in the oscillator menu choose RAM as source bank and the Wave that you just read. 

Have fun!
