Perfect condition Roland Super JD-990 with Roland Memory Card. Widely considered Roland’s best-sounding digital synth because of its high-grade digital-to-analog converters (DACs), individual tone panning, and flexible deep-architecture design that creates a rich, expansive stereo image

Sound Architecture & Synthesis

• Polyphony & Multitimbral: 24 voices; 6 parts plus a rhythm/drum part.
• Patch Structure: Up to 4 tones (waveforms) per patch combined via flexible "Structures".
• Waveforms: 195 base PCM waveforms built-in, compatible with JV-80 and JD-800 data cards/expansions.
• Advanced Synthesis Tools: Includes ring modulation, oscillator sync, and Frequency Cross Modulation (FXM) for an aggressive, analog-like bite.

Effects & Connections

• Onboard Effects: Simultaneous multi-effects processor including chorus, delay, reverb, phaser, distortion, spectrum/enhancer, and a 3-band mix output EQ.
• Audio Outputs: 8 total outputs organized as 4 stereo pairs (Mix Out L/R plus 3 Direct Output pairs).
• Display: Large 320 x 80-dot backlit graphical LCD screen displaying real-time envelope shapes and parameter values.

Filters & Modulation

• TVF (Time Variant Filter): Resonant low-pass, high-pass, and band-pass filters with dedicated multi-stage envelopes.
• TVA (Time Variant Amplifier): Amplitude control with dedicated envelopes.
• LFO: 2 LFOs per patch featuring expanded wave shapes (sine, triangle, sawtooth, square, trapezoid, and random/chaos waves) with tempo sync.
