Audity Zero Project - Keyboard and Sequencer
 Circuit Description
The original Audity sequencer never happened.
It was due to be developed as an expansion of the 4070 polyphonic keyboard, with a CRT and 8" floppy diskette storage. It was even
advertised separately in the Autumn of 1980. However by this time the Audity project was slowing down, as the Emulator project was taking off, and Scott Wedge simply didn't have the time to develop the sequencer code for the new keyboard.
 The Cloned Sequencer
With nothing to base the design on, I have instead taken an existing MIDI hardware sequencer and built it into the Audity Zero keyboard unit. I have chosen a Roland MC500 MkII as it has 8 tracks and floppy diskette storage. |
