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.

• Find: finds everything that matches the query and displays it in a list.

  • the order, row, and channel columns are as they say.
  • the go column of buttons will take you to the location of the result.

replace

you may select any of these to replace:

• Note: note.
• Ins: instrument.
• Volume: volume.
• Effect: effect type.
• Value: effect value.

all of these have the following choices for how they alter matches:

• set: changes matched data to this value.
• add: adds this value to matched data. it may be negative for subtraction. notes are calculated in semitones.
• add (overflow): as "add" above, but values will wrap around; for example, adding 13 to FF will result in 0C.
• scale: multiply value to this percentage; for example, scaling 1A by 150 results in 27. not available for "note".
• clear: erases matched data.

the following options also are available:

• Add effect: adds another Effect and Value to be replaced according to how they were found.

• Remove effect: removes last Effect and Value.

• Effect replace mode:

  • Replace matches only: replaces only the effect columns that match.
  • Replace matches, then free spaces: replaces matched effects; if there are effect columns without data, those will be filled in with the additional effect replacements.
  • Clear effects: overwrites effect data with replacement effects.
  • Insert in free spaces: replaces nothing; replacement effects are inserted in free effects columns when available.

• Replace: performs the query specified in the Find tab and replaces it as directed.
