EES MIDI Retrofit

EES Technik für Musik ·

This kit is quite rare. See also EES Instructions, and David Clarke's patch conversion tools for EES, which convert back and forth to Syntech/Chroma Cult format; and discussions on EES sysex format in ChromaTalk Archives December 2003 (threads midi sysex, midi sysex - EES Decode, midi sysex - EES Decode(d), and SYX2EES).

Benjamin Fehr writes: "The EES-MIDI Interface is an external box which gets connected with the Chroma by the RS-232 Interface. The box itself contains 3 switches on the front end. Two of them are considered to do the multi-timbral assign (1, 2, 3 or 8 channels/different sounds), the third changes the keyboard 1 octave up. Beside them are two MIDI-connecteurs for IN & OUT. On the rear of the box a switch changes the MIDI channels from #1-8 to #9-16, a temporary switch starts the MIDI data dump." [April 1999]

Here's a picture from Marc Günzel [21010086]:


Jesper Ödemark [21010135] writes, "it seems to be trustworthy indeed. Failed me once, but that was me having forgotten to switch on the SidStation that is on the midi chain between the Atari and the Chroma." [March 2005] Ernst Eimer [21010299] writes, "The interface is connected to the 'computer interface' 25-pin connector. It offers MIDI In/Out/Thru and can be programmed with switches on its housing. The most important feature is: MIDI SysEx! The interface comes with a bank loader/manager and a sound editing program [the Kirschning Chroma-Editor] which is very useful, since the Chroma isn't easy to program. The sound editor shows all parameters graphically on the screen, i.e. the 'patch' parameter uses the block diagrams that appear in the Chroma's manual (parallel filters, ring modulator etc.). The program was designed for the Atari ST, but it also runs on my PC with the 'PaCifiST' emulator. The emulator only provides MIDI out, but that's better than nothing. With the bank loader came the two factory preset banks and some other banks." [March 1999]

Joachim Farbowsky writes, "It supports some kind of a Midi-multi-mode in which up to four voices can be addressed indepenently." [February 2000]
