Are you really sure you don’t want to use them ?
.ot files add +12db by default for recordings, so you loose 12db.
From my experience and some tests, if you want to add +12db to your record, you can set the track you want to record (T1) Amp Vol at +63.
You can decrease Level, it won’t change recording level. Level 64 is -12db compared to Level 127.
You can hear the same level with Main out if you set either :
- Level 127 / Vol 0
- Level 64 / Vol +63
- Level 64 / Vol 0 /+12db in Attributes.
Recording level depends on Vol (and attributes, Fx), not on Level.
