Der Chroma-Editor (Chroma Editor)

Oliver Kirschning <>

The author writes, "Let me say a few words about why I made the Chroma Editor. First of all, I have to admit, I don't own a Chroma, and I never did! Neither a Chroma nor any other synthesizer. I can play drums and piano, but I am not experienced with sequencers etc. It was my uncle who had a Chroma. He was unsatisfied with the rather uncomfortable operation and tried to take advantage of my programming skills. So I started programming, for the most part for fun, and a little for the chance to earn some money (must have been around 1988, I think; I was still in school!). The project kept growing for a long time, I added the bank loader/sound libraries. I took endless hours to get it running, and sometimes even more time to 'debug the documentation' which had some little but important errors. We also talked to Wischiolek, who built the MIDI-Interfaces. When I think of 'money per hour,' it definitely was NOT worth it. But it was fun and I improved my programming significantly, so I don't want to miss that experience." [September 2004]

This picture "shows the opening screen with the copyright notes. As you can see, this copy that I have bought only a week ago has the serial number 31." [June 1999]

The File menu contains two items: Delete File and Quit. "The next menu allows to program a small sequencer. The memory space (Speicherplatz) indicator shows how much time is left for the sequence. You can use the recorded sequence to play through all sounds of a bank."

With the Bank menu "you can load or save a bank or you can send to or receive a bank from the synthesizer. You can change the name of the bank or play all sounds through. And you can display additional information on each sound. ... [When renaming a bank] you can store additional information on the sound bank. If you look at the screen layout you will notice the grids right to the sound names. There you can determine which audio output (0 to 3) should be used. When you double click the sound number, the patch editing screen will appear."

"There you have direct access to all sound parameters. You can change any parameter just by clicking on it with either the left (count down) or the right (count up) mouse button."
