Here is a vintage Yamaha DX7IID vintage Synthesizer / Keyboard with expansion "E! Card" modification. I tested the synthesizer for sound (see video). Buyer welcome to test / inspect. Rough shape keyboard case is free, if wanted. Synthesizer sold As-Is with no warranty or guarantee. https://offerup.com/redirect/?o=d3d3Lm11emluZXMuY28udWs= DX7 II D (D stands for dual timbres/outputs). The bitimbrality allows for using layer and split modes for a two-part multitimbral performance. Overview E! CONSISTS OF a single circuit board that is installed neatly inside the DX7. All E!'s functions are accessed directly from the DX's existing front panel by means of five special software "pages": Memory, Function, MIDI, Scales and Physical Control. In practice, the system behaves as if it were a part of the DX7 way of life from day one. Memory E! STARTS OUT by adding lots of memory: enough RAM for up to 320 sounds - or voices, as Yamaha call them - in 10 banks of 32. To save you the maths, that's ten times the memory of the standard DX7. Things look even better when you consider that unlike a standard DX, E!'s RAM is capable of storing function parameters with each voice. And because E!'s function parameters include everything Yamaha's do plus programmable volume, note ranges, and a host of other setup features, you'll be getting a lot of new features not previously available. Performance There are no fewer than five keyboard modes available to let you play your DX and a slave in different configurations. Normal Mode behaves like a regular DX. Rolling Mode alternates notes between the DX and the slave to produce interesting results when playing chords: some notes sound on the DX while others sound on the slave. Float Hi Mode lets you play the DX with your right hand while playing the slave with your left; E! keeps track of which is which on its own. Track Hi Mode sends only the highest note currently being played to the slave, while the DX sounds all notes. And Local Off Mode simply severs the direct connection that otherwise exists between the DX's keyboard and its own sounds - especially useful if you use your DX as a controller for a MIDI sequencer. E! also features a key limit function that lets you define upper and lower note limits within which both the DX voice and the MIDI slave will respond. A complete set of MIDI data filters are available for both incoming and outgoing MIDI data. SysEx, Sustain Pedal, After Touch, Mod Wheel, Breath Controller, Foot Controller, Pitch Bend and Program Changes may be ignored (with "In Filters") and simultaneously blocked from transmission (with "Out Filters") in any combination. E! also provides a series of Local Filters that mimic Local Off Mode. But rather than blocking the DX from responding to notes played on its own keyboard, these Local Filters block the DX from responding to its own controllers. This lets you send a patch change to the system without changing the sound you're playing on the DX, for example. IF YOU'RE PLANNING on holding on to that old DX or perhaps picking up a used one cheap, E! is definitely a worthwhile investment. Considering the price tag, E! would be a pretty good deal if all it did was store 320 sounds. From https://offerup.com/redirect/?o=d3d3LnZpbnRhZ2VzeW50aC5jb20=: The DX7, a classic FM synth, gets a make-over with three significant updates. The updated models feature a more sturdy chassis with actual push-buttons replacing the cheaper and less reliable membrane buttons of the original DX7. The two real time sliders (that allow for control of user-programmable parameters in real time) are larger than before. Internally, the biggest improvement is the updated 16-bit digital circuitry for cleaner and much less noisy sound quality. Patch memory has also been doubled from 32 to 64 voices. Additional general improvements include enhanced MIDI support, micro-tuning capabilities, aftertouch controlled pitch bending, and multiple LFOs. DX7IID models also added bi-timbrality with keyboard split and layering capabilities. This allows two voices to be layered in dual mode, providing very rich combinations of sounds that would otherwise be impossible with the original DX7. Voices could also be split across the keyboard, for a two part multi-timbral performance capability Like the DX7, these updated models may have been used by Kraftwerk, Talking Heads, Brian Eno, Depeche Mode, The Cure. https://offerup.com/redirect/?o=d3d3LnZpbnRhZ2VzeW50aC5jb20= A third party expansion called the "E! Card" added 8 voices layering, 4 banks of internal memory, and a full sequencer, turning the DX7 mk2 in a machine perfectly able to compete with the workstations of the following decade. Features 2-channel 6-operator 32-algorithm FM tone generator. Improved FM technology delivers superior sound quality. Full compatibility with existing 6-operator FM voices. Dual, split and single play modes. Stereo outputs. Dual continuous sliders for data entry and rea
