Razor Edit on Env : set to MIN-0-MAX

[ferropop]

Are there any existing scripts that might achieve these 3 actions?

ORIGINAL :



MIN :



ZERO :



MAX :



I envision being able to "navigate" a Razor Edit selection over an Envelope with the arrow keys, and have quick actions to set between MIN-0-MAX and maybe actions to Expand/Compress RE, all from the keyboard.

value = 0 ------ minimum envelope value
value = 1 ------ maximum envelope value
value = (0, 1) - all the values between (ie. 0.5 will be halfway up the envelope)
It will be slightly off for track volume envelopes between (0, 1), but 0 and 1 will be accurate, requires SWS.

local value = 0.5 --tweak this

local o = 0.00001; 
reaper.Undo_BeginBlock(); reaper.PreventUIRefresh(1)
for i = 0, reaper.CountTracks(0) - 1 do
  local track = reaper.GetTrack(0, i)
  local _, re = reaper.GetSetMediaTrackInfo_String(track, 'P_RAZOREDITS', '', false)
  for s, e, GUID in string.gmatch(re, "(%S+) (%S+) (%S+)") do 
    if GUID == '""' then goto continue end
    for j = 0, reaper.CountTrackEnvelopes(track) - 1 do 
      local envelope = reaper.GetTrackEnvelope(track, j)
      local _, env_guid = reaper.GetSetEnvelopeInfo_String(envelope, 'GUID', '', false)
      local _, _, r_GUID = string.find(GUID, '%"(.+)%"')
      if r_GUID == env_guid then
        local br_env = reaper.BR_EnvAlloc(envelope, true)
        local _, _, _, _, _, _, min, max, _, _, fader_scaling, _ = reaper.BR_EnvGetProperties(br_env); reaper.BR_EnvFree(br_env, false)
        local r_val = min + (max - min)*value
        if fader_scaling then r_val = reaper.ScaleToEnvelopeMode(1, r_val) end
        
        local s, e = tonumber(s), tonumber(e)
        local _, sv = reaper.Envelope_Evaluate(envelope, s - o, 0, 0)
        local _, ev = reaper.Envelope_Evaluate(envelope, e + o, 0, 0)
        local _, pr_ev = reaper.Envelope_Evaluate(envelope, s - o, 0, 0)
        local _, n_ev = reaper.Envelope_Evaluate(envelope, e + o, 0, 0)
        reaper.DeleteEnvelopePointRange(envelope, s - o, e + o)
        if pr_ev ~= r_val then reaper.InsertEnvelopePoint(envelope, s, sv, 0, 0, false, true) end
        if n_ev ~= r_val then reaper.InsertEnvelopePoint(envelope, e, ev, 0, 0, false, true) end
        reaper.InsertEnvelopePoint(envelope, s + o, r_val, 0, 0, false, true)
        reaper.InsertEnvelopePoint(envelope, e - o, r_val, 0, 0, false, true)
        reaper.Envelope_SortPoints(envelope)
      end
    end
    ::continue::
  end
end
reaper.PreventUIRefresh(-1)
reaper.Undo_EndBlock("Set envelope range to: " .. math.floor(value*100 + 0.5) .. "%", -1)

BirBird you are a beast, thank you.

For the "0" state with envelopes like Track Volume, I'm trying to hack in a "reset points to default" line at the very end, which should properly set them to 0dB rather than being off like you mentioned.

And also gonna try to figure out "tilting" the razor selection.

Wouuld be SO fast to edit envelopes based on the grid using the numpad, 4 + 6 being L + R, 7 + 9 tilting UP the Top Left/Right respectively, 1 + 3 tilting DOWN the Botton Left/Right respectively. And with the BirdBird script above, 8 would MAX, 2 would MIN, 5 would RESET.

A complete workflow for ripping up the envelope lane with grid-based edits.

It's a start!

...now thinking the ability to Grow/Shrink the razor edit out to the next gridline, from the Num Pad (maybe with a modifier on 2+6) would complete this.

...also modifier on 8+2 (up/down) to "Shift RE contents up/down a bit" to get variations between MIN/RESET/MAX would be vibesss.

All from the numpad!
