==== Multimode ====

In addition to the outdated sysex documentation, at least in firmware 1.15, a protocol for the multimode is implemented

^ Label ^ Value ^ Description   ^
| MULR  | 01h   | Multi Request |
| MULD  | 11h   | Multi Dump    |

==== User Wavetables ====

^ Label ^ Value ^ Description    ^
| WTBD  | 12h   | Wavetable Dump |

A wavetable dump is used to transfer wavetable data to the Blofeld. Each wavetable is transferred as 64 consecutive wave dumps.

^ WT ^ WN     ^ Location                  ^
| 50 | 00..3F | Wavetable 80, Wave 1..64  |
| 76 | 00..3F | Wavetable 118, Wave 1..64 |

==== Sample Code ====

Convert a 21 bit signed integer (provided in three 7-bit characters) into a 32 bit signed integer
