OA (Open Architecture) Synthesis System
OASYS 88 88 key Real Weighted Hammer Action (RH2)
* The key weight of the RH2 keyboard differs in four stages across the pitch range (with low notes
being heavier, and high notes being lighter), delivering a playing feel similar to that of a grand
piano.
OASYS 76 76 key synth-action keyboard
Synthesis Types HD-1 (High Definition Synthesizer)
EXi (Expansion Instruments)
Maximum Polyphony Maximum polyphony varies depending on the synthesis type, as shown below. The actual polyphony
will vary depending on the synthesis types and effects being used.
HD-1
AL-1
CX-3
STR-1
MS-20EX
PolysixEX
MOD-7
Dynamic voice allocation between synthesis types: exclusive system intelligently allocates resources as
necessary, so that the user does not need to specify fixed numbers of voices for each type.
Preset PCM 314MB (1,505 Multi Samples and 1,388 Drum Samples).
Bundled EXs PCM Libraries 313MB: ROM Expansion EXs1 (229 Multi Samples and 1,483 Drum Samples; lossless compression
reduces RAM size to 284 MB).
503MB: Concert Grand EXs2 (10 Multi Samples; lossless compression reduces RAM size to 464 MB).
PCM RAM 500MB
* The amount of PCM RAM will change depending on how you use the included EXs, system
software, and options.
Wave Sequences User Memory
Preload
New Wave Sequence features include support for stereo multisamples, enhanced tempo
synchronization, real-time modulation, dual AMS outputs per step, crossfade shapes, and more.
Advanced Vector Synthesis Control oscillator volumes and synthesis & effects parameters via the Vector Joystick and the tempo-
synchronized Vector Envelope.
Single/Double Structure Single = OSC1 only; Double = OSC1 & OSC2. Double mode lets you layer two completely separate
synth voices, each with their own velocity-switched oscillator, dual filters, EGs, LFOs, etc.
Oscillator 4 velocity zones per oscillator, with switching, crossfades and layers.
Each zone can play mono or stereo Multisamples or Wave Sequences.
Filters Dual resonant filters per voice.
Single, Serial, Parallel, and 24dB(4-Pole) configurations.
Low Pass, High Pass, Band Pass, and Band Reject modes.
Driver Per-voice nonlinear driver and low boost.
EQ Three bands, with sweepable mid.
Modulation 3 Envelopes, 2 per-voice LFOs, Common LFO, 4 Key Tracking generators.
AMS - modulate a large number of synthesis parameters via LFOs, Envelopes, and real-time
controllers.
2 AMS Mixers - combine and process AMS sources. Add, multiply, smooth, quantize, and more.
Advanced Vector Synthesis Control oscillator volumes and synthesis & effects parameters via the Vector Joystick and the tempo-
synchronized Vector Envelope.
Modulation Common Step Sequencer: 32-step sequencer with smoothing, adjustable step duration, and tempo
synchronization.
AMS - modulate a large number of synthesis parameters via LFOs, Envelopes, and real-time
controllers.
Common LFO, 2 Key Tracking Generators.
EQ Three bands, with sweepable mid.
