Yamaha DX21

   0 reviews  -  2484 views

    32 Performance Memory System, programmable with data on play modes, key shift, detune and pitch bend. It will automatically recall these real-time performance parameters as well as the voice or combination of voices.

    FM Digital Synthesis

    Instead of VCOs, VCAs, and VCFs, the DX21 uses "operators" (a digital sine wave generator combined with an envelope generator) to produce sound that can be used alone or in combination with other operators.

    Voice Memories

    32MB RAM (Random Access Memory) voice memories, organized in two banks of 16 voice selector keys.
    Pre-Programmed Voices Built In

    128 pre-programmed voices permanently stored in internal ROM (Read Only) memory. Organized into groups of 8, these voices can be loaded individually or in groups into the 32-voice RAM memory.

    Three Ways to Play

    Two FM Tone Generators allow voices to be selected three ways: Single, Dual, or Split play modes.

    MIDI Functions

    A broad range of MIDI functions make the DX21 exceptionally useful in virtually any MIDI system application.

    Cassette Storage

    A built in cassette interface allows an unlimited number of voices to be programmed and stored on cassette tape. Cassette voices can then be loaded into RAM memory when need
