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 find term 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.
  • -: remove find term. if only one find term exists, it is cleared.
  • Add effect: adds another Effect and Value to the term, each set representing additional effects columns.
  • Remove effect: removes last Effect and Value from the term.
• +: adds another find term.
• Search range: restricts the find to the whole Song, the current Selection, or the currently viewed Pattern.
• Confine to channels: restricts the find 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 terms and displays it in a list.
  • the order, row, and channel columns are as they say.
  • the go column of buttons will snap the pattern cursor to the location of the find.

replace

• the replacement term contains:
  • Note: note.
    Ins: instrument.
    Volume: volume.
    Effect: effect type.
    Value: effect value. all of these have the following choices for how they alter the found data:
    • set: changes found data to this value.
    • add: adds this value to the found 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 data.
  • 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: finds everything from the "Find" tab and replaces it as directed.
