(Designed for Windows but will run on a Mac using Oracle's VirtualBox...)
Freeware for most Windows versions that allows you to send WAV files from your computer to an Akai S900/S950 MIDI digital sampler (no other models are supported). Can send WAV files, either mono or stereo, left or right channel, from 8-64 bits. S950rs.exe is RS-232 only and does not support MIDI at this time! Sample-transfer speeds up to 57600 baud (using a USB cable with a Prolific chipset, running Windows XP in Oracle VirtualBox on Apple Mac Sierra 10.12.6).

You will need a USB to DB-9 male cable: DTECH 10 Feet USB 2.0 to RS232 DB9 Serial Port Adapter Cable with FTDI Chipset Supports Windows 10 8 7 and Mac Linux. and a DB-9 female to DB-25 male adaptor (you need one without hex nuts or they get in the way): DB9 Female to DB25 Male, Adapter, (Serial Port) Molded.
