A Synthesizer in VHDL emulating a Roland JP 8080
(c) 2010 Jürgen Schuhmacher
A special setup of the VHDL Synthesizer together with a virtual MIDI controller is used to emulate a vintage Roland JP 8080 Synthesizer.
Virtual MIDI Console
A Computer ( PC or NOTEBOOK) is used to run the virtual console and drive VA-Synthesizer via MIDI.
Common 8 Bit MIDI is used in this case. Control is performed with MOUSE or attached physical MIDI controller via routing. See also the Microwave Console for details: MicroWave XT-Emulation
Front End for Keyboard Control
Cinema 4D Software is used to reproduce the Roland JP 8080 Surface of the real Synthesizer. Knobs are dynamic during rendering phase and thus can be recorded at various angles to show 3D-behaviour from within the PC-program.

MIDI - Data is sent to the FPGA board which produces the sound. VA Synthesis and Wave Table Synthesis is possible. See the Audio DSP pages for details.
