Yamaha TG100 midi sound module

Just got myself a little half rack size little module sold early 90s, simple to use, buttons fiddly and no backlight on a tiny LCD that you can hardly see. AWM 192 voices and 10 drum kits, 28 note poly, general MIDI level 1, has digital reverb. 15 volts DC at 500 mA. Sounds are quite thin but handy to add to other sounds.

See here for more info and support.

Here is the insanely loud demo song
