Filter Patch Outputs:
-
HP output from the first filter - the 6db HP.
-
Three filter type outputs from the second filter - LP, BP, HP. The synth itself is hardwired to
output the LP filter internally.
Gate / Audio Trigger Switch: A switch to determine the source for the envelope's gate signal.
When turned off the envelope will be gated by incoming midi gate's through a connected MVC.
When turned on the envelope will be gated by incoming audio (audio triggering).
Trigger Threshold: Determines the sensitivity of the audio triggering circuit, only in use when the
envelope is in audio trigger mode.
ADSR: Controls for attack, decay, sustain and release.
Decay Mod: The depth of bipolar modulation applied to the decay of the envelope by the decay
external input.
Release Mod: The depth of bipolar modulation applied to the release of the envelope by the
release external input.
Slope: Slope control for the decay and release portions of the envelope.
Vel: Bipolar velocity control over the overall level of the envelope. Center position indicates no
modulation. The OS20 Vel input needs to be connected to an MVC's vel output in order for the
envelopes to respond to velocity.
Envelope Patch Outputs:
-
Three output points for the normal as drawn envelope shape, an inverted form of the
envelope and an output for the gate signal (as generated by incoming audio into the
external trigger input).
VCA Input Crossfade: Crossfade between the hard wired VCA input (the sound coming from the
filter section) and the VCA's external input.
VCA External Mod Switch: When turned off the VCA is hard wired to and controlled by envelope
2. When turned on the VCA is controlled by a modulation signal connected to the external mod
input.
Shape: This knob affects both the internal pulse shape as well as the internal tri saw shape. For
the pulse shape the width of the pulse is affected (center position is a square), while the tri-saw
mixes between a triangle at the left position and a saw at the right position (with a mix of both in
the middle).
Shape Mod: Depth of modulation applied to the shape parameter via modulation
Rate: The speed of the lfo when not in sync mode. From 0.01 to 400hz.
Div: The speed of the lfo when in sync mode. Measure divisions based on the device's BPM
setting. Provided are 19 divisions: 64bar, 32bar, 16bar, 8bar, 4bar, 2bar, 1bar, 1/2p, 1/2, 1/2t,
1/4p, 1/4. 1/4t, 1/8p, 1/8, 1/8t, 1/16p, 1/16, 1/32.
Sync: Turns sync mode on and off.
