Digi-Gurdy (electronic MIDI enabled Hurdy Gurdy) upgraded to include an on board sound card, thus allowing it to have a headphone socket.
Volume of all channels can be adjusted from the menus on the Digi-Gurdy screen.
It can still connect as in previous versions, via a USB cable to an iPad running a suitable soundfont player such as the Bismarck bs-16i app. It can still connect via a plug-in MIDI Bluetooth transmitter to an iPad or other device.
