Autodafe has released the Cynthcart MIDI Controller, a free MIDI editor for the Cynthcart on the Commodore 64.
Cynthcart is a popular cartridge for the Commodore 64/128 that turns the computer into a standalone analog synthesizer, using the onboard SID chip(s).
With Cynthcart and a MIDI interface you can hook the Commodore to your Mac or PC and/or play it from an external MIDI keyboard.
This MIDI Editor allows to easily edit and automate most of the synth parameters using MIDI-CC commands, such as Cutoff and Resonance of the filter, Attack and Release of the Oscillators, LFO rate and Depth as well as PWM and other parameters.
Cynthcart MIDI Controller is available as a free download in VST an AU plugin formats and standalone software for Windows and Mac.
