====== Korg Electribe ES-1 ======
{{ :media:image:hardware:es-1.jpg}}
Cool sampler and sequencer. Comes with lots of sounds, patterns, and songs built-in, and it's pretty fun just messing with those, or replacing the samples and hearing the existing patterns with new sounds.

Only downsides for me are that I can't freely play a sample across the notes of a connected [[MIDI controller]], and that loading samples is a bit tedious.

===== Loading Samples =====

Loading samples from a [[SmartMedia]] card has a few restrictions:

  * Files need to be named in order, EG: 00.WAV 01.WAV 02.WAV 03.WAV 04.WAV (extension can be upper- or lowercase)
  * 100 files max in the root directory. Dunno about using subdirectories.
    * You don't need to keep you samples here, it's more a temp space as you'll move the individual samples into sets/banks and save those back onto the card.
  * 8- or 16-bit, 32KHz. .WAV or .AIFF. If you use a rate other than 32KHz playback speed will be distorted.
  * You can format the card in the ES-1. It's [[wp>File_Allocation_Table#FAT12|FAT-12]].
  * If you get ''Er.3'' when loading samples that means you're out of space.
    * Actual sample space seems to be ~2.2MiB in my experience.
  * You have to load each sample one-by-one!

==== Renaming ====

I use [[wp>GPRename]], which I have hooked into my file manager, so I can select a directory and launch it.

  - Go to the 'Numerical' tab
  - Set 'Add numbers starting at' to '0'
  - Make sure 'increment by' is '1' (should be default)
  - 'and after' field needs to have your file extension; so '.wav'
  - Make sure 'Keep existing names' is set to 'No' (should be default)
  - Hit 'Preview' to make sure things look right, then hit 'Rename' if they do.

It'd be nice to script the whole renaming and converting process, so I'll add a command line renaming guide at some point maybe.

==== Converting ====

With [[Audacity]]:

  * Select all audio, Tracks > Resample... select or enter '32000'.
  * If you want to make it mono: Tracks > Mix > Mix Stereo Down to Mono.
  * File > Export > Export as WAV and set encoding to 'Signed 16-bit PCM' or 'Unsigned 8-bit PCM'

With [[ffmpeg]]:

...

With [[SoX]] (and [[bash]]):

''for file in *.wav; do sox $file -r 32000 -b [8|16] -c [1|2] [optional output directory/]$(basename $file); done''

  * ''-r'' is sample rate
  * ''-c'' is channels
  * ''-b'' is bit depth
  * 'optional output directory' has to already exist

===== MIDI =====

Default mapping for a keyboard is (copied from the manual):

^ Part      ^ Note name ^ Note number ^
| Sample 1  | C2        | 36 |
| Sample 2  | D2        | 38 |
| Sample 3  | E2        | 40 |
| Sample 4  | F2        | 41 |
| Sample 5  | G2        | 43 |
| Sample 6A | C4        | 60 |
| Sample 6B | C♯4       | 61 |
| Sample 7A | F♯2       | 42 |
| Sample 7B | A♯2       | 46 |
| Slice Sample | B2     | 47 |
| Audio In  | A2        | 45 |

I would like to be able to take a sample and play it across the whole keyboard, but you can't. It doesn't even respond to a controller's pitch wheel.

You do have access to all the knobs via MIDI [[MIDI#NRPN|NRPN]] messages (which, to summarise, are just groups of regular MIDI CC messages), except for the effects section and the accent button for some reason. NRPN is annoying to do in [[Reaper]], and the instructions in [[https://files.ryliejamesthomas.net/manuals/korg_electribe_es-1.pdf|the ES-1 manual]] are obtuse, so I haven't tried this yet, but changing the Pitch/Speed would be useful. Theoretically with the right software, you could map keyboard keys to NRPN messages.
