The programs were an experiment for me and the vidoes were to show what you could do with a BC.
The software is written just for the Korg DW6000 and there is another video for a Yamaha TQ5.
The Korg one only works on the DW6k, but as there was a lot of common sysex messages with the 4 op synths like the DX21 etc a lot of these should also work.
Writing a generic program to cover a few synths is really difficult let alone all synths and so there needs to be a separate application for each synth.
In short, my software won't work with the ATC-1 and you would need to write a program for your ATC-1.
Will it run on a Mac... there are ways to run PC programs on the Mac if you want to try mine out, but you would need a DW6k or a 4op Yamaha..
All the best
