The SD-1 comes from a long line of Ensoniq's evolving TransewaveTM wavetable digitalsynthesizers. It began with Ensoniq's earliest synthesizer, the. That led tothe, then the and (the latter featuring an on-board sequencer) and then to theSD-1 (and it eventually led to the ). The SD-1 allows for additive synthesisusing waveform modulation, a sort of wavetable synthesis.
This puts itinto a unique class of digital synthesizers along with the series and Waldorf series.The SD-1 can create all sorts of acoustic, electric, digital, andanalog-like sounds. Its piano sound has over 1 MB of 16-bit waveforms togive it a full and rich realistic tone not found in other digitalsynthesizers of the time. That piano sound was just the beginning ofwhat would become the 'Perfect Piano' used in Ensoniq's and E-mu/Ensoniq's series 'Sounds of the ZR'ROM expansion soundset.The SD-1 has 21 voices of polyphony just like its predecessor, the VFX (a 32 voice version later became available).A single patch can contain up to 6 of the 168 waves in its ROM memorythat can be combined and layered. Patch for lotr bfme2. Advanced and analog-like synthparameters including its dual multi-mode digital filters, three 11-stageenvelopes, LFO, and 15 modulation sources allow you to further shape andmorph your sounds. There's even a built-in 24-bit VLSI dual effectsprocessor with reverb, chorus, flanging and delay. The SD-1 also has astandard 61-note keyboard with velocity sensitivity, polyphonic aftertouch andfull MIDI implementation with 12 channels for multitimbral functions as well asfour 16-bit DAC outputs.Like the VFX-SD, the SD-1 has a professional quality on-board sequencermaking it a complete all-in-one music production workstation. This is a24-track sequencer with 25,000 note capacity andit holds up to 60 sequences and 20 songs.
There is quantization (96 ppqn),real-time or step entry, looped or linear mode, and auto-punch in/out.Tracks can be set to control the SD-1's internal voices or external MIDIequipment, or both at the same time! An on-board 3.5' disk drive allowsyou to store your programs, sequences, songs, and even MIDI SysEx data.The SD-1 is compatible with all VFX and VFX-SD program librarys too. An optionalSQX-70 Sequencer Expander upgrades the sequencer memory from 25,000 toover 75,000 notes. Related Forum Topics.
