Tune your 808 in REAPER

Drop the 808 you load into ReaSamplOmatic5000. Read its note here, save it tuned, then set the sampler so every key plays its own note. RS5K has no root key field; Pitch@start does the job, and this page gives you the number.

Mika, the resident

Mika counts the semitones down from note zero, so you don't have to. REAPER takes the number.Pick a WAV, AIFF or MP3 of one hit. It is read in this browser.

In REAPER, step by step

  1. Read the 808 above. Leave the target on the nearest note and save the tuned WAV: the cents are gone, the length is the same.
  2. Put ReaSamplOmatic5000 on a track and drag the tuned WAV onto its black waveform area.
  3. Set Mode to Note (semitone shifted): each key now moves the sample by a semitone.
  4. Leave Note start at 0 and set Pitch@start to the number in the line under the result: minus the note's MIDI number. Note start then plays the sample that many semitones down, and the note itself plays it at its own pitch.
  5. Play the note in a MIDI item. ReaTune on the track shows whether it lands.

Pitch offset moves the sample in semitones on top of that mapping. With the tuned WAV it stays at 0.

Checked against the REAPER User Guide (Media/MIDI preferences: middle C, MIDI note 60, labelled C4 by default, and the octave name display offset; ReaSamplomatic5000 instances for kits) and the REAPER Effects Guide (ReaSamplomatic5000: Mode, Note start, Pitch@start, Pitch offset, Portamento, Obey note-offs; ReaTune), with the REAPER Blog's RS5K tutorial.

REAPER and this page count the same octaves

REAPER labels middle C, MIDI note 60, C4 by default, as this page does, with A4 at 440 Hz. So the note above the graph is the note REAPER shows: an 808 at F1 (43.65 Hz) is F1 in REAPER's piano roll, MIDI note 29.

Unless someone changed it: Preferences, Media/MIDI, MIDI octave name display offset. At −1, REAPER says C3 for middle C and every name moves down an octave; the MIDI number, and so Pitch@start, stays the same.

Slides and the 808 in RS5K

RS5K has Portamento for slides between notes, Pitch bend for how far a bend may move it, and Obey note-offs, which stops the sample when the key is let go instead of letting the tail ring.

One RS5K per sound: a kit is several instances, each with its own note range. Only the 808's instance needs the note mapping; a kick or a clap stays in Sample mode, which ignores the note.

Then make something of it

The note goes into Brumm as a bassline on an 808, in a running club track. The WAV is yours: 24-bit, mono; a WAV keeps its sample rate.
