find/replace
Furnace has a powerful find-and-replace function that can take the repetitive work out of mass editing.
find

all data that can be found within a pattern can be searched for here.
a query contains:
- Note: note.
- Ins: instrument.
- Volume: volume.
- Effect: effect type.
- Value: effect value.
all of these have the following choices for what data will be found:
- ignore: ignore this.
- equals: match the given value exactly.
- not equal: match everything but the given value.
- between: match anything between and including the given values.
- not between: match anything outside the given range of values.
- any: match all values.
- none: match blanks only.
the following options also are available:
- -: remove query. if only one query exists, it is cleared.
- Add effect: adds another Effect and Value to the query, each set representing additional effects columns.
- Remove effect: removes last Effect and Value from the query.
-
+: adds another query.
-
Search range: restricts search range to the whole Song, the current Selection, or the currently viewed Pattern.
- Confine to channels: restricts to the selected channels and the channels between them.
- Match effect position: chooses how the order of effect types and effect values will matter when finding them.
- No: no attention is paid to what order the effects appear in.
- Lax: matches effects if they appear in the same order as selected above.
-
Strict: effects may only match in their correponding effects columns.
