what?

Oilcan is a monophonic digital-style percussion voice. At its core, Oilcan is two sine waves capable of basic FM synthesis. These operators are wavefolded, then mixed into two stages of clipping.
Oilcan is arranged in timbres. You can think of each timbre as its own drum. Each time Oilcan triggers, it picks a timbre based on the note you're sending.
You can find all of Oilcan's params in the OILCAN > param group.

Change SELECTED TIMBRE to edit different timbres. The selected timbre's params will populate below.
Below the timbre params is the MACROS section. These params non-destructively multiply timbre params as they're played, acting as performance controls.
Below MACROS, you can find trigger params for temp-saving and temp-loading timbres or macro settings. This can be used as a performance control, or to copy timbres to new slots.
Below temp controls is the save system. Everything is saved with your psets - this is for sharing sounds with other norns.

signal flow

param name	description
`FREQ`	Base frequency
`SWEEP TIME`	Percentage of release time spent sweeping towards base frequency
`SWEEP INDEX`	Depth of pitch sweep
`ATTACK`	Rise time. Affects all envelopes.
`RELEASE`	Fall time to silence. All other envelopes use this time as a reference - changing this param affects all envelopes.
`MODULATOR RELEASE`	Percentage of release time spent releasing the modulation operator to silence.
`MODULATOR LEVEL`	Multiplier for the modulator envelope height.
`MODULATOR RATIO`	Multiplier for the modulator's frequency relative to base frequency.
`FEEDBACK`	Modulator FM feedback. 0 is a sine wave, 10 is tuned noise.
`FOLD`	Amount of wavefolding applied to operators at start of signal chain
`HEADROOM`	Amount of headroom before the signal hard-clips. Lowering `HEADROOM` applies a filthy compression effect.
`GAIN`	Signal multiplier into a soft-clipping waveshaper.
`ROUTING`	Linearly pan the modulator between 0 (carrier modulation only) and 1 (mix with carrier for output)
`LEVEL`	Clean level control.
