It features 6 Mb of our highest quality 44.1 kHz waveforms, a powerful and flexible synthesizer architecture with extensive real-time control, 4 pairs of stereo outputs, and a dynamic multi-effects processor for creating stunning synth textures, as well as expressive acoustic instruments.

• Selecting Patches

The Super JD features 192 Patches - 128 Preset Patches (A/B), and 64 User Patches (1). An M-256E card can hold an additional 64 User Patches (C).

• Using Controllers with Patches

Most of the Patches in the Internal Bank are setup to respond to controllers "4 "and "1" or "11" for real-time control of various parameters. Use a controller keyboard or sequencer that can transmit one or both of these controllers to shape the sound of the JD-990 Tones in real-time.

Patch 1-11 DeepSEAmphony is a good example of how these controllers can be used. Controllers can be assigned to control a wide range of parameters including pitch, cutoff, resonance, level, and LFOs. Two controllers can be assigned for each Tone.
