Ensoniq ES5506 instrument editor

The ES5506 instrument editor contains three tabs: Sample, ES5506 and Macros.

Sample

for sample settings, see the Sample instrument editor.

ES5506

ES5506 contains a filter, which is somewhat configurable. there's also a hardware envelope, but it's probably most useful for smoothing.

you may use this tab to set up ES5506-specific parameters:

• Filter Mode: sets filter mode.
  • HP/K2, HP/K2: run high-pass twice using filter K2.
  • HP/K2, LP/K1: run high-pass using filter K2, and then low-pass using filter K1.
  • LP/K2, LP/K2: run low-pass twice using filter K2.
  • LP/K2, LP/K1: run low-pass using filter K2, and then again using filter K1.
• Filter K1: set coefficient 1 (K1). effectively controls cutoff.
• Filter K2: set coefficient 2 (K2). effectively controls cutoff.
• Envelope count: set length of hardware envelope (it's very short even at highest value).
• Left Volume Ramp: how much to change left volume on every envelope step.
• Right Volume Ramp: how much to change right volume on every envelope step.
• Filter K1 Ramp: how much to change filter K1 every envelope step.
• Filter K2 Ramp: how much to change filter K2 on every envelope step.
• K1 Ramp Slowdown: increases length of K1 ramp.
• K2 Ramp Slowdown: increases length of K2 ramp.

Macros

• Volume: volume sequence.
• Arpeggio: pitch sequence.
• Filter Mode: sets filter mode.
• Panning (left): output level for left channel.
• Panning (right): output level for right channel.
• Pitch: fine pitch.
• Phase Reset: trigger restart of waveform.
• Filter K1: K1 sequence.
• Filter K2: K2 sequence.
• Outputs: ES5506 has 6 stereo output (total 12). select which pair of outputs to use.
• Control: reverse/pause sequence.
