Can I use a Casio DH Digital Horn such as the DH-100 or DH-200 with the TURBO VL chip?
A.) Yes but you will need to use a mapper to map the DH-100’s Aftertouch data into breath controller (CC#2) data. Midi Solutions makes a device called the MIDI Solutions Event Processor that will do the trick. Also, Anatek made the “Pocket Mapper” but they are no longer in business. These can sometimes be found on the used market.
