Yamaha DX11

Yamaha DX11 is one of the latest models of the legendary DX series that Yamaha produced in the 1980s. The DX11, released in 1988, four years after the DX7, offers 8-part multitimbrality, an advantage that previous DX synthesizers (like the DX7 or DX9) did not have.

The DX 11 has a polyphony of 8 voices, and contains a 4-Operator Digital FM synthesizer, like the DX9, in contrast with the DX7, which contains 6 operators), LFO, reverb, DDL delay, pan and tremolo. The DX-11's multitimbral features allow players to spread various sound patches across different "zones" of the keyboard. It also allows complex ensemble performances using external sequencers or while playing live using "Performance" patches. The "Quick Edit" function is a helpful utility for programming sounds (which more laborious on the DX7 or DX9), thus the user doesn't have to delve into the complexity of FM synthesis just to make a few simple changes on a sound. These quick edits affect the tone, envelope attack and release times. Unfortunately, there are no on-board arpeggiators or sequencers. It has 61 Keys (velocity and aftertouch sensitivity), and its memory includes 128 preset patches, 32 performance patches. It also has a slot for external cartridge memory (holds 64 patches) and cable to be connected with a cassette deck for data transmission and reception.

The DX11 is somewhat underestimated in that while it could not boast the huge selling success of its counterpart, and stocked only 4 instead of 6 operators, it is a fully upgraded version of previous DX models.
