Connecting from the ULTRA-CURVE PRO AES/EBU output to an S/PDIF input will probably not work, because the copy prohibit function present at the S/PDIF device will be triggered by a channel status bit, or possibly another AES/EBU defined bit, preventing data transfer.

6.4 MIDI connections

The MIDI (Musical Instruments Digital Interface) standard was developed in the early 1980s to allow electronic musical instruments from different manufacturers to communicate with each other. The use of MIDI has developed over the intervening years to the stage where it is now common to find complete recording studios operating entirely on a MIDI basis. The centrepiece in such a studio is usually a computer running a sequencer software which not only controls various keyboards, samplers and sound modules, but can also run the programming of outboard effect devices, typically digital reverberation and delay units. The ULTRA-CURVE PRO may be controlled in real time in this studio environment.

The MIDI connectors found on the rear panel are of the universally used 5 pin DIN type. You require suitable MIDI cables to connect the ULTRA-CURVE PRO to other MIDI devices. Normally complete cables will be purchased for this use, you can of course make your own, using a high quality cable with two cores and shielding (like microphone cable), with as connectors two good 180 degree DIN plugs. Pin 2 (center) is connected to the cable's shield, pins 4 and 5 (left and right next to 2) carry the two cores, pins 1 and 3 are not used. MIDI cables should have a maximum length not exceeding 45 feet.
